interesting. can you post some examples, would love to see what sort of results you're getting. i'm thinking about getting the OM adapter for my Olympus E-330.
do you have to leave the zuiko's wide open on canon or do they function relatively normally?

In my profile the pictures named Elia & Geo are taken with a zuiko 50 1,8 on 20D, the Island and Window #4 with zuiko 85-250mm on 20D, I will post more pictures in the next days. They function normally, the diafragms and focusing are of course manual, but with the af confirm adaptor it's quite easy the focusing too. It's not so fast as with an AF lens but if you're not in a hurry there isn't all that difference. The first two pictures are original, the other two are corrected with lightroom. I really love the sharpness and the colours of the old zuikos

The OM lenses are amazingly sharp on digital (I use them on my E-500). People say that the 50mm f/1.4 is soft unless stopped down... But I think they just can't focus!
This one was shot at f/1.4:

I also use the OM 300mm f/4.5, which is hard to focus, and suffers occasional fringing issues. This one was shot at f/8:

Dozeprat, you do have to use stop-down metering, but that's really much easier than it sounds. Just mount it on the camera and set it to program. Set the aperture you want on the lens, and you'll be able to see the effect in the viewfinder, which may take a little getting used to, but it's not that different. The camera will automatically pick a shutter speed to match the light coming in. You can also operate it in Aperture priority and full Manual, I believe, not sure about shutter priority. They really work very well on the E-330.

Hello Alessandro, I bought it used from a guy in Germany on the bay, I've seen that there are many, you should look for an OM-EOS AF confirm adapter with chip, the prices are different and the quality is not granted, you can try to buy one and see how it works, with mine I've been lucky!

Yours is similar to this:
cgi.ebay.it/ADATTATORE-OLYMPUS-OM-CANON-EOS-con-MICRO-CHI...
or that:
cgi.ebay.it/AF-Confirm-OLYMPUS-OM-LENS-to-CANON-EOS-EF-RE...
?
The price is so different...

It's the first one, you may look on german and british ebay, there could be auctions that you can't see searching from Italy

nice to see that the OM Zuikos continue to be used on the digcams. It effectively doubles the focal length though, doesn't it?

i believe its 1.6x for a canon.. and maybe a bit more for the olympus due to the sensor being smaller.

tim at is right. effective focal length is doubled on a 4/3rd camera since the sensor is so small. So a 24mm lens basically gives a 'normal' field of view.
I love OM gear but am not a fan of Olympus digital: tiny viewfinders, noisy sensor, huge crop factor... but I imagine telephoto junkies might feel a little different.

You're right about telephoto junkies, fitting old lenses to a 4/3 camera doubles the focal length.
With an adaptor on my 4/3rd camera, my old lenses become the equivalent of a 100mm f1.8, a 270mm 2.8 and a 130-400m f4 zoom.
The big zoom is a bit of a handful: it wasn't built for tripod, so you end up hand-holding it, which usually means shooting wide open (or nearly).
But the quality is OK.
The 1.8 and 2.8 are brilliant, very crisp; and because they are so fast, you can shoot at lower ISOs which counters the noise issue
(If there is a noise issue: heck, you don't know what noise is until you've shot film!)

I have a Canon 30D that I'm using with a Zuiko 50/1.8, a Zuiko 50/1.4, and one or two more OM-mount lenses, as well as two M42-mount lenses: a Super MC Takumar 50mm f/1.4 and a Jupiter-9 85mm/2.0.
You can get some seriously good results from OM glass on DSLR's. Although I have to admit that the Tak takes precedence in my bag over the Zuiko 50/1.4, as it seems to be a little sharper wide open.
Good glass is still good glass even when it's old -- and for a photographer on a budget, there's nothing better. :)

Ordered an adapter off eBay last week so I'm waiting patiently for it so I can get my 55mm onto my 40D. I'm a tad worried that it'll be hard to focus properly at 1.2 though.
Why can't newer cameras have split prisms built in. =p

I have an OM-2n with the 28mm 3.5, 50mm 1.4, 100mm 2.8, and 135mm 3.5 primes.
I recently purchased a Fotodiox adapter to use the lenses on my DMC-L1 after I found out that focus confirmation was available. Even with FC, it's not a convenient experience at all.
After reading through the manual again, I eventually tried using live view and turned on the L1's manual focus assist which does a 4X or 10X digital zoom at the touch of a button. Bottomline: I'm in MF heaven now. No guessing, no eyestrain. The L1 is a fantastic option if you want to mount vintage glass and take tack sharp photos.

Matt_Lew - I believe you can swap out the 40D stock focussing screen for a split prism one.

@haphazart1 - Yeah you can, but it's an "after market" one which I'm not 100% keen to do. Maybe in the future. The EF-S screen that Canon makes does make is easier to manual focus apparently, but it still lacks the prism.

Matt_Lew - what I did was to get a split prism focusing screen for some other canon EOS camera and then grinded it down to size for the 40D!
I modified this instrucable - www.instructables.com/id/Modify-a-Canon-EOS-300-into-a-ma...
A tip for this would be to cover the screen you're going to use with a layer of sellotape (or clear packaging tape, it's called different things in different countries) and make sure you use lots of water when you're wet/dry sanding it down.
Works a treat!

To echo what Equivalence says earlier in this thread, yes, I also love the Olympus OMs but wouldn't think of buying one of their digital SLRs because of the sensor size and related noise and quality issues.
Perhaps if enough people keep saying this, Olympus will make an SLR with a larger sensor (full frame?) and an OM compatible mount .. just day dreaming ....
In the meantime, I think I may buy a Canon and a lens adapter ...

Just got my adapter today. The lens is a tad wonky on the adapter e.g. it can move a little to the left or right when I've focused to the very end of each focal point, but apart from that it works perfectly, both in Av and M.
Only annoying thing is that 1.2 is hard to focus at, but I'll practice. =]

Yeah, it can definitely take some getting used to, focusing with a relatively dark and small screen.
If you want some serious viewfinder envy, pick up any manual focus 35mm SLR and compare the viewfinders. :-)
Anyway, the focus will get easier with time. And if you haven't yet, check out this group:

More info than you can shake a stick at. :-P

Yeah I still prefer to use it on my OM-4. I'll also use it on my EOS 5 too but that also lacks a split prism. =p

I have a split prism on my 30D, but it's still a little dark for my taste.

You can't see the split prism lines in this photo, but you can see the microprism collar. Honestly though, it's just not bright enough for me to use except in daylight or indoor well-lit areas. Maybe I should have opted for the slightly more expensive, brighter version.

Has anyone experienced the dandelion focus indicator? Apparently you add to your OM adapter and it indicates when focussed. My eyes are struggling to see through the puny E-410 viewfinder.
