Looks like the Chinese have finally reversed engineered 2.4ghz triggers. They should do a better job at translating the Chinese to English though, the description is hard to understand.

Questions I have would be "What is the fastest sync speed these can operate at?", and does the statement "It can trigger two flashed at the same time just use one receiver." mean the trigger is limited to only two receivers?

Anyways nice find Leon, I will be following this thread...

CotswoldPhoto says:

A few answers. Max sync speed is 1/250

Max range is 100m.

Transmitter uses CR2 (claimed up to 20,000 releases)

Receiver uses 2 x AAA (up to 45 hours on standby).

Frequency is 2.4GHz

Many versions for different cameras (for use a remote shutter release).

The package blurb says:

Yong Nuo new 2.4GHz wireless remote controls are the advanced design of CTR-301 and YN-128

I got a blurb picture from China:

I also found this link that gives some additional information.
Hong Kong Yong Nuo Photographic Equipment Co. Ltd

This is the first "poverty wizard" radio flash trigger not based on a 433Mhz signal that I have seen. I purchased the ISHOOT IS PT04 system a couple of weeks ago. If I had I known about these I would have purchased them instead given they are 2.4Ghz.

As for cost, the closest 2.4Ghz competitor would be the CyberSyncs but they are three times the price.

It will be interesting to see how these perform.

ive been stuck since getting the canon 5d, the triggers i currently have create banding on my sensor. hopefully these work just as well, less the sensor noise.

someone buy them already

Here are some general benefits of 2.4Ghz over 433Mhz.
2.4 GHz uses 7X smaller antenna than 433 MHz because the wavelength is 10 cm vs 69 cm for 433MHz.
2.4 GHz is legal more places worldwide.

I am not sure of any other benefits...

kenkyee says:

"No lock down on the transmitter."

Kris: if this is like their other wireless triggers, what you do is hold the transmitter button down, then wait for the light on the receiver to change color. When it does this, you can release it. The next time you press the transmitter, it'll close the shutter.
I used it that way for long exposures (>30sec)...

The transmitter is kinda ugly though :-)

sune: let us know how well yours work. At these frequencies, they should be a lot more reliable than even the V4 fleabay triggers. And where did you find a way to buy receivers separately? I couldn't find it in the stuff they posted for sale. I need a wireless shutter release anyways, so this looks like a good option for me...

Kenkyee - when I said lockdown I actually meant that there is no nut that can be locked down on to the hotshoe of the camera - the skyport also has this design failing and are prone to falling off the camera.

I was just about to pull the trigger (no pun intended) on Cybersyncs (1 transmitter, 2 Receivers). I guess I'll wait on a few reviews on these new 2.4G YongNuo ones.

I know the CyberSyncs are rock solid and it almost seems too much to hope that the 1st gen Chinese 2.4G triggers will be problem free but fingers crossed. I have a Cactus V2s set which are failing me badly.

There are 2 reasons why I am waiting, one is that the triggers will be a belated birthday present so if possible I want to reduce the cost to the giver, and two while I don't think the 230USD for the cybersyncs (Intl order) is expensive for what you get, I am thinking of getting more triggers in the future. Adding 2 more triggers would drive the total cost to over 400USD as opposed to 110USD for the YongNuos.

kenkyee says:

Kris: guess you run Canon gear? I've never needed any sort of locking nut for the hotshoe mount on my Pentax gear.

BTW, I emailed them and asked if they could do a package of one transmitter and 4 receivers and they said they'd put one up for $99. Doesn't sound bad at all if they're reliable and I need a wireless shutter trigger anyways.
When someone gets it, could you confirm that pressing and holding the trigger will lock the shutter open so you can do something else for 5-30min exposures? A 2nd press should release it. That's how it used to work...

CotswoldPhoto says:

Well, first looks are positive. I didn't want to use this as a camera shutter trigger, so bought the C1 version, as that has shutter cables with the 2.5mm jack for the Canon 400D etc.

The cables you get are:

#1. Coiled Rx to stereo 2.5mm. The Rx end is a little 3 pin female connector with red aluminum screwlock. Stretched length is 1 meter.

#2. Coiled Rx to mono 6.35mm (1/4"). The Rx end is a little 3 pin female connector with red aluminum screwlock. Stretched length is 1 meter.

#3. Straight PC to mono 2.5mm. PC isn't screwlock. Length is 0.25m.

#4. Coiled screwlock PC to screwlock PC. 1 meter.

Battery bays are easy to access.

The Rx hotshoe for the flash is nicely made. My SB-900's fit nicely. The pins all match up and the locking pin works a treat. The mount under the Rx is a plastic coldshoe with metal 1/4" x 20 thread.

The Tx hotshoe for the camera is metal. It fits my D200 nice and snug. It does not have a ring to tighten it, but it seems quite tight. The pop-up flash won't lift. The PC socket is on the front and is screwlock.

As for tests, I wanted to do that outside, but this is Britain, and it is summer, so it is raining - hard.

I'm taking my bits up to my dad's house.

It's a massive 16th century stone farmhouse (once the Earl of Warwick's farm estate house, hence the size). That'll test it!

I'll take my little Kodak P20's too, coz they wouldn't fire with other remotes and have no sync port. Got my cellphone too.

kenkyee says:

or just give a flash to a neighbor down the block that you can see from the window, then point your camera and fire to make sure the flashes show up.
I'm curious how the shutter release works as well. I'm fairly certain that if you hold the transmitter down long enough, it'll change color and the shutter will be locked open like their previous version.
Another quick test would be putting the camera w/ transmitter near the flash (e.g., at half arm's length) and see if it still fires (the V2s triggers get pretty flaky when this happens. I hit this occasionally doing product photography w/ the V2s...

p.s., your dad's house sounds like a great location for model shots :-)

OK.

All tests with D200 on manual and 1/250, tested with SB-900 and Kodak P20 flashes on manual. Tests repeated loads of times.

Next to each other (literally 3 inches apart from camera to flash). 100% pass.

Amazingly, it fired the P20 (now these things are cheap on eBay), and I haven't been able to do that before because it was designed for a Kodak camera and the shoe is odd.

20m test (that's the length of my Dad's house. All passed

Next to a cell phone in use. No misfires. Next to a wireless router (same frequency - 2.4GHz). No problem.

Walls. It managed 3 walls (all about 2 feet thick ironstone).

It is still a torrential storm outside, so I'm not up for that! The next door neighbour is too far away across the fields.

One thing that is annoying is the lack of locking wheel on the Rx cold shoe to mount it. You need an adapter/mount with a 1/4" thread top (like the D Type ones in my stream), or a clamp (Stroboframe) type cold shoe.

The on/off switch for the Rx is good.

60 meters was as far as I could go and still see the flash. I placed it my dad's house that has a corridor running the whole way (20m) East/West at the West end. Then I walked (under an umbrella) to the bottom of his garden (East), so about 70 meters in total.

No problem.

I have a friend down the road with a Canon and 430 and 580's. I'll ring him tomorrow.

I took it into some woods too. About 100 meters with all the trees in the way. It's real dark (10pm here) and spooky with a half moon shining through the fast moving clouds and the water dripping off the trees and wildlife emerging after 12 hours of non-stop rain.

Looking good and we really appreciate your efforts. I'm more concerned that they fire 100% of the time at distances of 5-15m. But 200m is impressive. A few more positive reviews or impressions from others here and I'll probably place an order.

Jaroslav,
I would be happy enough with 1/250th but this is a strobist forum. Some have D70s, the fairly old but still on sale D40, or cameras like the G10. There are definitely occasions when a trigger capable of faster than 1/250th fire are handy.

blndcat: I am completely aware about the cameras with electronic shutter with superfast sync times.

I was just explaining that the performance of both triggers (the delay) will be very similiar, those two different times thet were mentioned will probably be the same for both of the cameras.


So far it looks we're saved - they seem to work perfectly. Yesss.
Posted 46 months ago. (permalink)

blndcat says:

jebx,
thanks, definitely useful to know! I think that one line supports what Jaroslav was saying. :D


Jaroslav,
Thanks, I guess I was wrong to compare the two different specs but they were presented as the same spec.

I get what you're saying about the theoretical delay/performance being similar, but without testing we don't know if it is. Stated spec from YongNuo Max Range: 100m, tested range: 200m (and so on)

The original Cactus V2 models were never reliable after around 1/250th. And sometimes better with the pc port than the hotshoe, super-fresh batteries etc.

These 2.4GHz seem to be reliable off the bat and across the board. One or two more reviews will be good, if nothing else than to see if there are any quality control issues. Fingers crossed!

No, but there is an adapter to allow Sony flashes to connect to a standard hot shoe. The V4s will only work if you first fire the flash on camera, and then attach it to the receiver. Not sure if it's something to do with the flash itself or the V4s, but apparently Cybersyncs work fine.

If these Yongnuo triggers work reliably with the Sony flash then I might pick up a set.

Wait a sec...a while back I asked YongNuo about interference problems between their old shutter release and the V2s transmitters when using offcam flash and they released the initial version of this (sold on dealxtreme). AFAIK, this type of design is supposed to allow you to do wireless shutter release and flash at the same time...
Are you guys sure you need two transmitters? i.e., you can't press the one transmitter w/ a receiver on the camera and one under a flash?
Posted 46 months ago. (permalink)

CotswoldPhoto says:

kenkyee I had some of those dealextreme ones. They were the YN-16. Inside they were essentially still cheap and nasty. And you did need two sets to do as you want. If you used one Tx, the shutter would lift as the flash went off. There are timing delays in the shutter which would mean the flash would always fire too early.

Hi friend,

Thank you for your letter.

Yes, you can use those function in the same time.
When you press the shutter button in the transmitter, you can take a picture and make the flashes fire.

hkyongnuophotoequipment
==================
I want to use this as a shutter release and wireless trigger at the same time like this:

rf-602 receiver -> camera shutter release
rf-602 receiver -> flash #1
rf-602 receiver -> flash #2

rf-602 transmitter in my hand so when I press the shutter button, the camera takes a picture and the flashes fire.

Is this possible?
Posted 46 months ago. (permalink)

elv0000 says:

I'm guessing there would be a delay on the shutter while the flashes fire straight away.

But even if it can work just by using an extra transmitter on the hotshoe on a different channel, thats pretty handy atleast you've got a back up transmitter instead of different gear for a shutter remote.
Posted 46 months ago. (permalink)

CotswoldPhoto says:

In any event, the difference in price between one set plus an extra transmitter and two sets is about $6-8. Not bank breaking.

On a mechanical shutter there will be a delay, maybe not on an electronic shutter.

I did test this on my D200 quite a while ago.

bluecoaster72 says:

@kenkyee - I got mine Thursday evening and just tested it for you. I only have one receiver right now, but what I did was put the flash in the hotshoe and connected the 3-pin out of the receiver to my 50D shutter release. When i triggered the receiver from the transmitter both the flash and camera would fire but the camera didn't capture the flash output. It appears that the flash is firing before the shutter opens.

I think everyone that ordered these will be pleasantly surprised. I have a set of PT-04s and these are much better then those. The build is pretty good, they don't feel as rugged as CyberSyncs (I have a set of them), but they are pretty close. Only real negative is no lock down wheel on the transmitter or receiver.
