Can you get to the sensor on a G9? On my XTi, I remove the lens and have easy access.
If not, How would you get dust inside...that looks like a huge dust spec.

Nope, sensor is rather unaccessible on the G9. Should be all but impossible to get dust inside unless infared modifications or such were made... I imagine if something that large were on the front element, you'd easily have seen and cleaned it. Maybe try taking it to a trustworthy cam shop?

I think that's definitely on the lens.Even if the camera is no longer under warranty i would still send it direct to Canon and not via a camera shop.You may find that Canon won't charge for cleaning it as that makes for good PR.

No mods ;) actually, it's had the adaptor with at least a uv filter over the lens since new, partly for this reason.
It shows up pretty bad on the LCD and generally becomes less apparent when the camera focuses. Only on telephoto with the flex zone focus over the spot on a clear background does it come up this sharp. It shows on the LCD regardless of lens or focus settings ? I'm confused as to where it would be in the focal plane to always appear in the LCD?
Purchased in Nov... looks like spring break at canon service... It might be good Pr for Canon to clean it. It would be much better if a fixed lens camera that has been well cared for didn't have garbage inside the lens. grrr...
Thanks,
jeff

Canon service has always been good to me. If you have owned the camera less than a year, it's still under warranty. Send them an email, get a claim #, and send it in. I'm sure they'll take care of you.
Something else you might want to consider: I have an insurance policy on all of my camera gear that covers it against everything from theft to damage on my own account. I've had this policy on my 20d for some time now, but never added my point-and-shoot cameras. This bit me in the @$$ when the screen on my S3 went sour, so I'll be adding my new g9 to it today.
It's through my regular insurance agent and costs about 10% of the cost of the equipment per year. If anything gets stolen or damaged, though, you get a replacement with no deductible.

Hi All,
To update the saga... I got a claim # from Canon and gave them a call. Unfortunately, My original receipt is with my accountant... and usually, the first thing I do is photograph receipts... not this one...DOH!
Not to be outwitted by a piece of dust... I went at it with a new air can. Seems like a good blow into the battery compartment, usb door, around the lens etc has at least dislodged the crud from the field of view. I just hope it doesn't decide to re attach itself to the lens. It took a couple tries, almost the whole can...but at this point is certainly a happier ending than having to pay for shipping at the least.
@macwagen, might I ask which agency writes your policy. both loss and insurance are a write off for tax purps... given this experience, I think I might go the insurance route...

I have Erie Insurance, but I think most carriers will offer this sort of insurance. It's the same type that women will sometimes use to insure jewelry.

@Nolavox, don't use compressed air to clean cameras, ever!
All it does is move dust ,that was happily out the way and hard to dislodge to blow all around the camera. it can also smear lenses by dust which was in contact with lubricant (shutter, iris etc) being blown across lenses/sensors. This info I was told by several people who repair cameras over the years

@ Radical... I fully agree in the digital realm with an ostensibly sealed camera. I have a feeling that mine will need to go in for a periodic cleaning as i will bet the offending clod got sucked inside during lens extension/retraction. I have some nikon lenses that are not internal focusing and they tend to suck dust into the lens. as well. I'm just surprised by how visible this one was.
Although, I agree that compressed air can cause the problems you mention, I,ve been using it for 25+ years. For me the camera is a tool to be used in whatever conditions...if it breaks, thats the breaks (literally;0)
Sometimes in the field... a good sprritz along with the right brushes, fluids, prayer etc. is the only option... I do use a rocket and have used canned air (Co2) for years on motion film and video cams.. so far...
dotlinecorp.net/index.php?main_page=product_info&cPat...
I would say never used that canned stuff for computers.

I had the same problem with my first and now second G9. The first one was changed after tree weeks by the seller when presenting him such a bad area (but it looked more like dirt anywhere inside). No with my second G9 after two month there was the same. This time the seller had sent it to Canon for repair. They returned it with the note "optic changed" (whatever that means). The seller (from Saturn - a local store) told me that the will not repair it again (without comment) - without telling me what the problem caused.
What can be done against that - whatever this is? From Canon there is no answer and no suggestion what to do.
Had someone else such problems and got some more concrete answer from Canon?

I have several pieces of lint that are stuck inside the lens. I'm really disappointed, especially for a camera only 5 months old. I've never had to return a camera so soon. Canon's response to this will determine my future purchases.

I had my G9 for about a month and got exactly the same problem - a huge blob of dust right near the centre of the frame basically rendering the camera useless.
I presumed this was a manufacturing fault with the camera being supposedly sealed; however, maybe as mentioned above, the dirt was sucked in by the lens movement.
I'm pleased to say that the camera came from Amazon and they replaced it without complaint.
However, I'm worried to think that this may happen again as it's obviously a common problem according to the above comments.

I just bought the G9 at Circuit City. After a few hours I noticed it had a BIG dust thread inside the lens...I did shoot a few shots outside in a windy situation...returned it next day... Got the second G9 home and instantly noticed it had a crooked LCD...weird... really bugged me. Returned it yesterday...checked the 3rd G9 seems ok thus far, but I am bugged by the dust issue. I've had several Canon P/S over the years and have never had this worry...something inherent in the lens design in the G9? Chime in...

I have a A620 for 2 years and shot 12000 pics. Noticed dirts on lens elements after a few weeks shooting but didn't show up in photos. A month ago a big black spot appeared in all my pics. Someone said that may be dirt on sensor. Googled for days and took me a couple days to take the camera apart.. The morons glued down the sensor screws and had to be cut out. Spent $15 to get a Torx T3 to unscrew the sensor. Sensor was clean but 1/2 mm dirt spot was on the piece of tiny glass in front of the sensor. Used a knife to cut one side and peeled open the glass. Cleaned it and no more spot on photos. There were still many dirts inside the lens element that I couldn't get at this time. Looks like this is a common problem with many canon point and shoot. My friends A630 has dirts in the lens elements too. Buyer beware!

I've got tha sam problem, but as i see it, dust particle are in the lense. Thi sbore me to the max as the camera is only 6 monthes old and i always carry it protected.
it's a big deception for me as i thought i had bought a very good camera, it appears that the build isn't that good.
I'll bring it to the canon center, hoping they clean it for free.

Well, got my G9 back today after taking it in for repair under the warranty.
They 'replaced the optical unit'. Anyone know what that means exactly? Is the lens the optical unit? If so, does that mean dirt got into the lens and they were unable to remove it so had to replace the whole thing?
Rinaldo W also had 'optic changed'.
The mystery deepens...

I have found pollen to be a culprit for me... When extending the lens, the air volume inside has to increase... if there are particles small enough on the lens barrel... they will be sucked into the lens. I'm just keeping mine brushed or blown with co2 and it seems to be ok. I have some older nikkor prime lenses that have extending barrels for focus. They have visible crud inside of them... it does not show at their focal lengths in the final product... I believe the design fault is where this stuff is landing inside the g9 zoom lens.
The "optical unit" would be an engineers term for a "lens"... or anything in front of the sensor. Who knows what happens at canon if someone needs to "take a leak"...

-------
I wouldn't pay too much attention to the comment written on the repair sheet from canon. When I got a canon G6 back from repair, it said 'replaced LCD unit', and my LCD unit was definitely not replaced.....and there was nothing wrong with my LCD display/unit in the first place, since my repair was for other things. Initially, I had thought that they gave me the wrong sheet, but I compared the reference numbers on my own customer slip with their repair sheet, and the references matched exactly. It didn't matter that much to me. They did a great job with the repairs.

@Nolavox.
Why would I be concerned if you don't take me, or what I have to say on the possible design flaw of the G9 seriously?
Don't do anything about it - but your G9 will be useless after 1 year but then you're the type of sucker that Canon loves.

@WixPix: your G9 may still be under warranty, therefore, you should be talking to canon for a replacement.
Heaven forbid that I have similar experience within or after the warranty period then Canon will be hearing from the Court if they do not replace my gear + costs. Talking about it here in flikr won't help that much, litigation is what is needed.
Having said that, the guys at Canon are always willing to listen to customers' concern about their product and will hardly renege to fix your G9/G?.
Short and simple: if you have any issue with your G9, talk to Canon. If anyone can help "Canon Can".

Sorry cjb22... I'm in new orleans, work in news, and have heard a lot of negative speculation about a lot of things for the last few years. IMO Multiple threads about the same thing, just stir up the pot of opinion and speculation. Sure it's disappointing and I'm confident that if it is a real design defect canon will make it right. Although a bit sarcastic... a "disappointed" owners Gripe group on the interweb will get most any manufacturers attention... I don't have the time or inclination as I have bigger fish to fry right now... but I would join, just to put my name in the hat.
My G9 will go back to Canon before Nov... with maybe a link to this thread and yours as well... If the G9 proves to be "useless" after a year or two... I'll just go back to using my 34 year old Pentax Spotmatic...which has always made better images than the G9...dirt, water, Fungii and all... ;)

My Canon G9 is only 6 months old and already shows 4 visible dust particles behind the front lens of which one is located in the center of the lens. The comment of the Canon service center is that this is quite normal and acceptable and I really should not worry about this. My comment that a compact of this quality should be dust proof was directly moved into a dustbin, I just have to accept this 'feature'.
I noticed the dust because the autofocus is hunting when I try to focus a very close object with aperture set to maximal depth of field (f. 8.0). Since the dust is troubling the functionality of the camera (the litteral comment of the service person) I can send the camera to a local repair center to clean the lens.
I am worried is that the dust will enter the lens again very soon and I'm not very amused to send the camera (for a period of some weeks?) to a service center with an interval of 6 months. I think that Canon should solve this problem.
By the way, before the G9 I used a Canon 650 which could not be used in full sunlight, so this is my second Canon problem within about 8 months ..... with my very good experiences with several EOS versions in mind I get a little bit tired.

Hi guys, Im new to the group, I bought a used G9, I thought this was a G7 problem that would have been fixed. Now what Im wondering is
Has the problem happened again to anyone who has sent it in to Canon to fix the problem once already? Can Canon permanently fix the problem?

Thank you, did not find this via Google (or overlooked it). What did Canon since the first messages appeared on the web .... nothing?? According to the call center of Canon, Canon only cleanses the lens, with no guarantees that the problem will be gone (partially or fully) because no modifications are scheduled.

Mine is only 5 months old.
Have one visible dust. Gets darker, sharper & smaller when going min to max zoom. But it is still there in every configuration. Any ideas if dust is on the lens or on the sensor?
Dropped on purpose to table from 2in height two times to get rid of the dust. That made two of them! Dropped again and was able to get rid of the new one but the old one still remains there. Will never try the same as it can make 5 of them :)
Checked interior with a flashlight, several dusts are visible behind the first lens. Several 10s of them visible at the sides (on the black part) as well. :(
Does anybody have a Canon G9 Service Manual or dismantling procedures? The best solution seems to me that we have to learn how to dismantle and clean it on our own as it may and surely will repeat the same problem after warranty period.

[Dropped on purpose to table from 2in height two times to get rid of the dust.]
I think that 2 inches might not be enough. 2 metres should do the trick.
Only kidding hehe. Actually, I'd be extremely interested to know of dismantling procedures for the G9 as well. Is the G7 body just like the G9? If I ever needed to do it, if all other options failed, then I'd do a dismantling of the G9......but only if the procedures are for a G9 itself, and only if the procedures are really detailed.

As far as I know G9 and G7 shares the same body except minor differences as grip etc. My warranty is valid only in US where I've bought it and I'm not in position to send the camera to US from Europe. I will be sucking dust by a vacuum first. If not solved then I guess I've no option to go for a disassembly as I've done on notebooks many times. I hope that won't lead me to drop it from 20m. :)

I have the same problem with my G9
don't try to drop it - it will break. don't try to suck - this will only pull in more dust (most probably pollen). don't try to blow - this will force in moisture and dust.
My G9 is away at a Canon Service Centre. It is still under Warranty,
(its 3 months old)
I was told they will "clean it" once under warranty and was quoted
£ 40 to clean it if was out of warranty
"cbj22" has a point this is a serious design fault ,Canon should be doing somthing
Ive had 3 digital compacts and have never had this kind of problem

I still use an OM2n I've had this 20 years - I expect to have it another 20 years without a problem -
While I dont expect my G9 to last this long, I do expect it to last a reasonable amount of time - dust in the lens after 18 months perhaps is acceptable but not after 3 months - this is Canons top of the range Compact and they have screwed up
anyone know a camera tech - ask them why the G9 seems to suffer from this so badly

Hello,
I think it's time to call Canon for a official response to dust problem.
G9 it's a great camera, but the dust it's a great and real problem.
I think that as "Flicker group G9 users" Canon must respond....

It's a faulty design from the start. They should have put a controlled air inlet with a particle filter.
Solution: Free of charge cleaning for a lifetime & available worldwide no matter which country you bought the product.
Let's get together on a website to get the attention of Canon. Anyone have an idea where to host such webpage for free?

@Makrossi?
Did you call them?
Im still waiting for a response from Canon. I called their tech support line 10 days ago and received an email stating that Canon will try to answer the question - ('is it a possibility that due to the G9's design and engineering, dust is sucked in through the len/bellows mechanism to such an extent that shortly after the expiration of the warranty the Camera will become unusable without an expensive cleaning operation) - within 5 working days.

It 'a big problem!
I imagine that for Canon is a difficult problem to manage.
They could do a census identifying the machine with the serial number and ensure repair interventions lifetime.
I think it would be the best publicity may be with costs not excessive (knowing that the optical system is modular and building a good standard repair procedure).
Knowing to buy a machine who can assist you in an optimum manner makes the real difference!
In the event that Canon does not answer or did not provide the intervention I think that sales of this machine could fall dramatically.
We could prepare a standard email for require the repair.

Got the same problem here. The dark spot did start appearing yesterday. It's just so weird that I had been taking photographs like hour ago and then, after turning the camera on, *bang* - there it is. :(
Oh well, I bought the camera a few weeks ago, so I might just try my luck and take the camera to the service.

I haven't got dust in my fairly new G9, and I'm hoping that I don't encounter this issue. I'm thinking of getting a lense adapter, for preventative measures, but that might interfere with the onboard flash......plus it would turn the G9 into something else that it really isn't.

If I may chime in with the tale of my experience...
From day one my G9 had a speck of foreign matter on one of the inner lens elements. Fortunately this one did not show up in photos.
Roughly 3-4 months later I started seeing a spot on images, mostly at longer zoom lengths and under brighter shooting conditions. The spot gained a friend, and both spots started becoming more prominent.
Sent the camera back to Canon for repair and they "replaced the optical unit" as with others. But the original speck of dirt on the inner lens element was still there as were both spots showing up in images.
Made a phone call to Canon and sent the camera back again with sample photos marked up to point out the spots. At least this time shipping was on their dime.
The original speck on the lens is gone this time, and the absence of a tiny scratch on the black ring at the end of the lens indicates that this time the assembly really was replaced.
So far so good, but I must wonder "for how long"?

That was fast. Took my G9 to service at Monday and yesterday got a message it's repaired. Going to see if it's truly repaired in few hours. :-)
Don't know if the Canon Service Center got their hands dirty with my camera as I took it to InfoCare (Powermill), which handles all the services from the retailer I bought the camera from.

Below is the Canon's response to my email:
Thank you for contacting Canon product support. We value you as a Canon customer and appreciate the opportunity to assist you. I am sorry to hear that your G9 camera appears to have dust inside the lens.
Unfortunately, to have the camera serviced under the original Canon one year warranty it would require sending the camera to the service center in the USA. Canon does not offer an international warranty for its digital cameras. The camera is covered under warranty in the US if it is purchased in the US. If anything happens to the camera while it is in another country, we recommend mailing the camera to a contact in the states that can mail the camera for you to our Factory Service Center.
If you wish to get the camera repaired outside the US, the service facility will charge for the repairs. We apologize greatly for any inconvenience this may cause.
Please mail your digital camera to a US contact who can forward it to the Factory Service Center shown below. When shipping your camera, please be sure to remove the memory card and batteries. You are not required to send any accessories or manuals when shipping the camera.
Be sure to include your name, street address (no P.O. boxes, please), telephone number, and a letter describing the issue with the product.
Since it has been less than one year since the camera was purchased, we ask that you also include proof of warranty in the form of a copy of your sales receipt.
As we do not provide RMA numbers for service, we suggest using a trackable and insurable service (i.e. UPS, Federal Express, Priority
Mail) to ship your camera. Please package the camera very securely in a sturdy shipping box to prevent damage during shipment.
Please send your camera to the following address:
Canon Factory Service
1440 Chase Ave.
Elk Grove Village, IL 60007
Telephone: (800) 828-4040
Business Hours: Monday - Friday 8:00 a.m. - 12:00 midnight ET, and Saturday 10:00 a.m. - 8:00 p.m. ET (excluding holidays)
Upon arrival at the Factory Service Center, your camera will be logged in to our repair database and assigned a repair number. Next, the camera will be examined and you will be advised of the findings. If the required repairs are covered by the warranty, the repairs will begin immediately, and you will not be contacted. When the repairs are complete, the camera will be shipped back to you via Federal Express.
The length of time for the repair will be dependent upon the nature of the repair and availability of parts, if needed. Usually, warranted repairs are completed within approximately ten to fourteen business days of the camera's arrival at the Factory Service Center.
All decisions regarding warranty coverage are made by the Factory Service Center at the time of repair. If the repair entails something that is not covered in warranty, a written estimate will be sent to you at the address that you have provided. The repairs to your camera will not begin until you approve this estimate and make payment arrangements.
If, after receiving the estimate, you do not wish to have the camera repaired, please inform the Factory Service Center of your decision as soon as possible. If you decline the estimate, the camera will be shipped back to you unrepaired.
Once you have confirmed with your shipper that the camera has been delivered, you are more than welcome to contact us for repair updates.
Please include your name, address, and telephone number, as well as the serial number of the camera, in all repair status inquiries. If you prefer to check the repair status by phone, please see the above contact information.
Please note that our U.S. Factory Service Centers are unable to accept packages from or return equipment to addresses outside the United States.
We hope this information is helpful to you. Please let us know if we can be of any further assistance with your G9 camera.
Thank you for choosing Canon.

Yes, that response means nothing at all. It's really a case of the representative saying 'ahh....let me see, which category of automatic response button should I select?....ahhh...this one. Done! Sent!'.

This one is the latest response:
Thank you for writing, I am sorry to hear that the issue continues to persist with the dust inside your PowerShot G9.
Canon USA has made no announcements regarding any "known issues" or "defects" with the PowerShot G9. This camera has not been recalled, and no service notifications were issued for this model.
As with any manufactured product, from time to time there are circumstances that require technical support or perhaps even repairs.
From what you have described, it sounds like a camera malfunction, the dust should not have been able to get inside the camera.
I really wish that there was more I could suggest, I am sincerely sorry for the inconvenience this may have caused you. Please let me know if we can be of any further assistance with your Canon G9.
Thank you for choosing Canon.

VERY BAD RESPONSE!!
He said basically 'Ehi, i'm sleeping do not disturb!'
Maybe it's time for a small class action?
I think I will not buy another Canon camera.

There is another note on this problem in this forum. I had planned to buy a G9 until I read the complaint about bad noise above ISO 400 ... so I waited! Then this problem showed up .... I am still waiting to buy a p&s. I have a couple of dslr and several lenses but am looking a p&s when I don't want to mess with 50 lbs of equipment.
Seems like Canon has stopped releasing new cameras. Perhaps they are trying to solve some of these problems?

It's obvious that G7 has the same dust problem. So, I don't think they are trying to solve at least this one. Except this dust issue I was happy with my G9.

Thank you for this very useful information. I just got my G9 for a few days and now this dirt issue started to worry me. So my question is how likely is this problem would happen to all G9 cameras? 10, 20, 50 percent or higher? Since it sounds like it is a defective engineering design, would this be something that would happen sooner or later?
I have 30 days return policy, so I'd appreciate your advice. If I return G9, do you think Canon S5 IS would be a good alternative.
Thanks!

Had the same issue with my one month / 3000 shots G9. amazing camera that suck all the dust around it . They are cleaning it right now under warranty. My advice - buy one and use it ONLY with the lensemate adaptor and the UV filter to protect it from all the dust.

I heard that they will clean it only once! No word on any recall from this design defect!

So eventually I spoke to a very friendly lady called Jackie Prentice based in Ellstree, UK in 2nd level support and although she was unable to comment on the issues of dust being sucked into the G9 lens mechanism she recommended that I write or send an email to MAUREEN ROLLS, Complaints Co-ordinator beyond 3rd level of support, based in Ellstree, who has direct communication with the Managing Director of Canon Consumer Imaging Centre:-
Canon Consumer Imaging Centre, Unit 130 Centennial Park, Centennial Avenue, Elstree Hill South, Borehamwood, Elstree, Herts, WD6 3SE, UK
Or email, and mark to the attention of Maureen Rolls (and Im assured she will read it) :-

Sprengstoff772- how long did it take for the process to send, have the lens cleaned and camera returned? I am so upset that my camera started showing this big spot of dust on the lens today and there is nothing i can do about it. This is prime season to be taking photos and I hate the thought of sending my camera off for over a month.

Hello, everyone. I've been keeping an eye on this thread for months and I'd like to share my recent experience with the G9.
After 4 months of use with no problems whatsoever, I took the camera with me to the kiteboarding pro world tour in Paros. Sand + Wind = the ultimate test to find out if the G9 is weather proof at all.
Turns out the test failed. I got 2 blobs of dust and one piece of fiber on the sensor after 2 days in the event; needless to say I was mad at how poorly constructed the camera was. Note that I have a lens adapter and a UV filter always ON the camera.
Of course, there was no way to send the camera back while on vacation, so I decided to take matters into my own hands. After a close examination of the images posted at qman.fotokala.ee/Kaamerad/PowerShotG7/index.html (thans to tngsrk for the link), I dismantled only the parts that revealed the sensor and cleaned that up. I also took the chance to remove the hot mirror filter inside the camera. The process is really easy if you're careful and methodical.
So I guess there IS a way to take care of your G9 after the warranty period expires; as it has been stressed by others (sometimes in a very vocal way) the problem will not go away, so instead of paying canon to clean your sensor, you should be able to do it yourself by using ONE screwdriver.
Unless the lens is packed with dust, you are never going to notice that on your shots. On the contrary, the slightest particle of dust on the sensor is going to ruin them. As I said, it's really easy to get to the sensor, but it's really hard to dismantle the lens completely.
My point: Don't worry about dust in the lens - it's dust sitting between the sensor and the diaphragm that ruins everything. Remove the sensor, blow in the exposed area and you'll be set.
If you also feel like removing the hot mirror filter, be warned that the white balance presets will be useless. You will have to set that yourself.
I have no idea if there's any other side effect related to this conversion. The camera will be able to capture great infrared shots with a proper filter, without having to stick to huge exposure times.
But I'd like to hear other reasons why it might be a bad idea to shoot normal stuff without the internal (or an external) hot mirror filter, apart from the WB issue.

Is there some advantage in removing the hot mirror filter?

I'm pretty angry at the moment, because the dust spot is back... Just after three weeks from service. Don't know what I'm doing wrong in handling the camera... I always have it in the case when I'm not using it. :/
It's quite unnoticeable at the moment, so I'm not going to take it to the service just yet. But I must say I'm quite disappointed to the camera because of this issue. :/

southparkbucket:
The world of infrared photography opens up if you attach an external filter that blocks non IR, visible light. Otherwise, you would have to use huge exposure times.
The thing is the camera will afterwards capture a great deal of IR light. The white balance presets will be useless, and apart from that, the colors will be distorted... so you will have to use an external filter similar to the internal one. Still, I guess the camera will be out of spec, since the new external filter will not be exactly the same as the internal one installed by canon.
I'm willing to hear other people's opinions on the matter, but this is going to get out of topic, so please just pm me. I would like to know if this is in any way bad for the sensor or something. Any comment is welcome.

Some time ago I contacted Canon because I observed focussing problems due to dust in my G9 lens. The Canon reponse was that I could send the camera to a service center and if they could reproduce my problem the lens should be cleansed - with a turn around time of about three weeks. My problem only occured when making macro shots, so the problem did not hurt me too much and I postponed sending the camera without any certainty that the problem should be solved. But hurray! Thanks to dust in the lens, and/or on the sensor, I have a black spot of about two by four millimeter (on the rear display), on each photo. Now I can be shure that the service center will clean my lens! And this result is achieved within 9 month after I bought it. Thank you Canon for your assist!

I had the same ting happen to my G9, it was just a few months old. Canon changed the lens assembly, everything ok now. Just hope nothing gets sucked in again, that lens is like a pump, and dust can easily get sucked into it. A design flaw if you ask me.

I have had to send my G9 to Canon Service for the second time in three months for sensor dirt problems. They've cleaned it twice under warranty. Here is a link to the sensor blob:

Here's a link to a picture taken at f8 of a white screen with my G9 - uncropped. About to send it to one of Canon's authorized "local" service centres - 100 miles away. I don't hold out a lot of hope for this ending well.....

How anything that size got in there I don't know. Anyone got a bigger one?!

This same exact thing has happened to me in addition to a nice little scrape on the front of the lens where the door rubs against when it closes. Ill try my luck with a can of air tonight.

This inevitable problem occurred with my G9 several weeks ago while I was camping. I sent back to Canon, and got it back earlier this week. They replaced the lens assembly on mine as well...looks like the problem is fixed for now, but it's bound to happen again. Anyone know if this design flaw is addressed with the G10? Next time this happens, the g9 may not be under warranty, and so I'll pretty much scrap it and buy another point and shoot...won't be sending this back again and again.

G10 is exactly the same on this issue, as i understood from its descriptions.The only way out i can see is a replaceable lens assembly. Not difficult or too pricey, but maybe with the addition one would be within the dslr price range.
Caps and extensions do not help, forcing the lens to suck dust from its back.

I just don't get why all the cheapo digital cameras that are out there don't have this same issue...I mean, I bought my wife a $200 Panasonic Lumix and she doesn't take nearly the same care to keep it out of elements or out of situations where dust may creep in, and it's been three years with no problems. I, on the other hand, bought the underwater case for the g9 so that when it's raining or snowing, or when I'm in a dusty area, I can have the camera protected, and a lot of good it did me.
*sigh*

Yes my G9 is the same, you can see several pieces of dust and lint on the back (inside) of the outer lens. When viewing with screed you can see a dark spot in the bottom left hand corner and the more you zoom in the darker it becomes. The spot only shows if the spot is over a plane or sky part of the photo but it is so anoying. I could not send the camera back to Canon as I was just about to go to Europe and deeded to take the G9 with me. The G9 is a fantastic camera but the dust problem is very anoying.

After 13 months of faithful service it seem that a tiny piece of fiber is now a permanent resident on my sensor. I just found that thread and I am happy to see that " I am not alone..". I will soon visit my friendly Montreal Canon service center and see what the outcome will be. Stay tuned.

I am thinking.. how much would a thread cost to Canon, so that the lens part would be removable... I bet it would much less than 5$...

I am already worred everytime I get my camera out and use it! I blow off all dust, but really it seems a joke of a camera in the dust aspects of it.
To carry the exact same problem over to the next model is also a massive failure on Canons half. If mine gets dust inside, well I would never buy another Canon in my life.

Use it at your own risk. I tried it, it worked for me!

Haha sucking it out seems odd, but if it works . Maybe a hoover would do a better job mind you. All risky I guess, but cheaper then a repair job thats for sure :)

I did use a hoover (actually a large shop vac)... but it was not until I tried a "blow job" that the blob dissapeared and has not come back...
at least, I did do a thourough job of cleaning the exterior before I vacumed and then blowed the lens...
apologies in advance....

Ahhh, at least you fixed yours :)
Keeping the G9 clean from dust I find fairly hard, it seems to be a dust magnet. The metal body just seems to have more than a plastic body attracts. Still I always blow away dust before I close the lens, so hopefully it will keep clean.

Strange, I was reading an article on this subject just today. It seems that this is a common problem with the G9 & G10. Do a search on google and you will see how common it is.

To my experience it is not only a G9 problem. It is only that in a dust-full world, such as in and near big cities or construction sites or... etc, there are millions of dust particles unseen from the eye. The lens compartment of all is not air tight (with the probable exception of the waterproof cams). So here is the problem.
It is not cleanable also. But i have seen none else being. Maybe a marketing policy, so as to make you buy a new one after some years, as the previous would become useless, or to make the dslr's more attractive.
Another interesting point is that they (Canon etc) never say a word anywhere about the issue. Probably out of touch with their customers. As they were on the ISO-sensitivity issue and suddenly they all hurried to show up more. As they were on the dynamic range issue and now more are interested.
