Let´s do something that can be easier for the people searching info about this radio trigger, post a reply with your camera brand, model, hot shoe flash brand and model, max sync speed you can achieve and distance.

Good Examples:
(not actual data it is just an example of how to present your info)

Nikon D300
Nikon SB 900 and SB 600
Max sync1/250th
No problems as a remote for the camera
Issues: none 50 feet tested


Canon EOS 5D
AB 800, Vivitar 285v,
Max sync 1/200th
No problems as a remote for the camera
Issues: no banding, no misfires, 100 feet tested


Pentax K20D
Elinchrom RX 600
Max sync 1/100th
No problems as a remote for the camera
Issues: can´t get the camera´s max speed, no misfires, 20 feet tested
(again this are only samples of what should be written, not actual data)

Bad Example:

My uber Nikon D3x was connected to the RF603, I was using a super great SB800 which is super awesome, but my cat got in front of the receiver and the static interference did something, blah, blah, blah, blah...

Please don´t do this:

"I don´t know how to connect it to my camera?"
"How do I change the batteries?"
"(input question answered in strobist 101)"

If you have questions about RF 602 do them in another thread please :).

Edit: thanks for adding your info the more the merrier :), Now you can do ctrl + F and type your camera brand and model to search info about it.

Pentax *istDL
Bought the Canon style Tx unit recommended for Pentax
Works fine as a shutter trigger.
My Tx wasnt wired correctly as recieved, so I took it apart and fixed it.
Cameras max sync is 1/180 but I catch the second curtain a fraction at that speed.
Best so far with RF-602 is 1/125 - green light doesnt come on with the half press which is likley why I dont get max sync
going to try a Nikon Tx and rewire if needed.
No misfires.
Used friends RF-602's. Mine are still in the mail.

- Canon 40D
- Nikon SB28 and Vivitar 285HV
- Max Sync: 1/200 (Same with PT-04 on my camera)
- 100% within studio range, haven't tested extremes but don't really feel the need to as I'll never be shooting football fields away. My friend tested it in his house and it still triggered through 3 walls and the length of his house.

only real issues i had is they sent me 4 shutter release cords??

***EDIT: I just tried the shutter release cord today on my D90, worked flawlessly, as everything has for me with this product. I'm so impressed by these triggers.

I modified 2 of my cables with 3.5mm mono plugs (you want the red wire and the screen/ground), since their choice of cables is a bit... non-practical (4 remote cables, one with a huge 6.35mm jack and an adapter to 3.5mm)

On to the testing:

Nikon SB-800 + LumoPro LP120
Max sync - 1/250 (D200's limit)
Problem - The Tx stays on sometimes even if the camera is off, this might be a faulty Tx.

I also tested using this as a repeater. I took the RF-602 Rx, and added an old PT-04 Tx on the hotshoe of the RF-602 Rx, and added a corresponding PT-04 Rx attached to an LP120, and it works. There is a small decrease in max shutter speed though.

my safesync not working(need help with them, different topic) so i didn't test my other HiVol Flashes.
distance: ? not tested
Issues: one of the receivers was DOA, talking to YN about that.
besides that everything is nice and dandy
samples: ( I was too excited when I received the set so I didn't setup my camera's WB and flash level was @full blast)

EDIT: after carefully looking at some photos taken in near darkness I found out that even @1/200 still gets a little banding, almost unnoticeable.
so I guess max sync speed on D90 is 1/160.

Nissin 360TW, 1 attatched to hotshoe, 1 using cable to miniphone plug.
Nissin 3200GT (hammerhead style) using safe sync to miniphone plug.
Max Sync - 1/200 with no banding, 1/250 with around 2mm of banding which is easily cropped out.
Will keep up with max frame rate of 3.6fps. Will be trying 50D soon to test max frame rate.
Range is around 250 feet at the moment, haven't found anywhere big enough to test further. No issues with interference, even tested with my IPhone strapped to the flash.

NB - blown one r/x due to using on an older Sunpak minilight, ested around 14volt output, so guessing 12v is max limit on r/x's.

SB-800 wakes up fine in standby mode. Shutter release works great.

Issues: I first tried using my SB-600, but it didn't work. Then I realized my SB-600 won't even fire on my camera! I don't know if these caused the problem or not. But the flash had been working fine until now.

I also tried a SB-25 that has some issues itself, but it doesn't fire with the RF-602s. It seems to "lock up" after I try to fire it. The buttons on the back won't resond until I push the red flash button on the SB-24. Even if I turn the flash off, it will stay on until I push that red button.

Just had an opportunity to really torture-test my set of RF-602s, so here goes:

Nikon D700
SB-800, SB-600, SB-26, and SB-24
Sync @ 1/250th

SB-600 doesn't wake from standby, but the others do.

Had my range-related first issues since I've been using these triggers: shooting at about 100 ft, through a stone-and-metal bridge over a river, I got about 60% misfires. The receivers were directly on the stone floor of the bridge, behind the stone side walls, so probably any receiver would've struggled. FWIW, my shooting buddy was using Elinchrom Skyport receivers in the same location, and got a similar mis-fire rate. I think if the receivers were separated a little bit from the ground (ie on light stands or something), it would've worked correctly at this range - certainly it does in open ground at 200-300 ft.

(Although I had previously considered it unnecessary, I'm going to have a go at some antenna modifications after this experience :-)

Also, I had a few instances over the several-hour shoot where the transmitter fell off the hotshoe of my D700, when it was slung off my shoulder. (Again, the Skyport transmitter had the same problem).

Also, we tried a ghetto-repeater setup (a second transmitter on a different channel slaved to a receiver on the first channel), which worked, but it dropped the sync speed to about 1/80-1/125 (unreliable timing).

Nikon D-40
Sync at 1/800 1/4 power or less, drops to 1/640 at 1/2, checked twice.
Wakes the flash from standby, no misfires in @ 600 shots, except some testing around 200'.

Haven't needed to use it through walls, but it has done fine inside when hidden in fridge, etc.

No cables sold for D40 remote, so none used. Still on original batts.
I do remove the battery from the Tx while it is in the camera bag, since there is no switch.

Canon5D Mk I
550EX, 430EX, Vivitar 283
max sync of 1/160th at close range for all flashes.

Tried fresh CR2 in the transmitter to no avail. I have 4 receivers and they all max out at 1/160th. The 5D is capable of 1/200th and both the hot shoe and PC cord pass that sync speed test with flying colors.

A bit disappointed.

Also, one of the shoes was mis molded, so it causes a flash to sit wonky when it's mounted to a stud or stand. I'm seeing if I can get that replaced.



for examples.

YN-460, 465, SB-28DX, Metz 54MZ-4i, 40MZ-2, 32CT-2, Braun 370BVC, Soligor TIF-380LCD.

wakeup works only with SB-28DX, even YN-465 does not work. I'm trying to understand the wakeup feature by analyzing the hardware ATM but I need to do some more research.

As the S5pro ist identical to Nikon D200 in camera part the max sync is the same.

If you have 2 sets and like to have more than 100m in distance: just put a trigger on the receiver to work as a repeater. Will work with mixed dedication (you can mix canon and nikon triggers, RX are suitable for all) and will do both steps as well as wakeup feature.
This works both for camera and flash triggering.

Also possible: syncro triggering of 2 and more cameras. The triggering camera must have TTL flash contacts if AF triggering is needed (so eg a FM2 does shutter release only), my S5pro could be focused and triggered by F-301 without problems.
scubajunkie PRO 6 years ago
I've done a little cross-brand testing recently... at least between Nikon and Canon. The transmitter foot pin arrangement is very different between the Nikon and Canon variants, just like one would expect when comparing the feet of a Nikon and Canon TTL flash. The receiver, on the other hand is identical for Nikon and Canon RF-602s. I had no problem waking Nikon or Canon flashes from either Nikon or Canon bodies so long as I used a Nikon transmitter on a Nikon body or a Canon transmitter on a Canon body.

If I put a Canon transmitter on a Nikon body, or a Nikon transmitter on a Canon body, I can still trigger and sync the flashes, but they do not honor the wake up. So in this cross brand configuration, if a flash goes into standby, half press will not wake it, full press will only wake a Nikon flash (but flash does not fire), full press will wake and fire the Canon flash, but it does not sync). Then the next time the shutter is fired, flashes will fire and sync correctly.
microbug_de 6 years ago
sure, this could not work, but if you trigger the first step manually per Tx button press it will also wake up all flashes.

ATM I do not know exactly how the wakeup works electronically, I only found out that on Nikon it uses the pin on the upper rigt side for this, not the TTL pin. I'll go deeper in that next time:)

hadai You sure you have a Canon Transmitter ? With a Nikon transmitter on a Canon 5D you only get 1/160 and not 1/200.

Yes, I'm sure. Verified by the seller and pin arrangement. Turns out it syncs fine with my wifes XSi, so... After I've lived with these for awhile, I've tempered my disappointment. For what I do, a third of a stop of extra ambient occasionally isn't the end of the world. Overall, I'm pleased with the radio performance. The only minor complaints are two-fold; first, the on/off switch (it's buried under a 550EX, so a bit difficult to turn it off when I want to leave everything set up overnight or something). The second minor complaint is how the male shoes on the receivers are a bit thinner than the little flash stand's receptacle. Need to put a piece of paper or tape in there to it doesn't fall off.

scubajunkie PRO 6 years ago
Here's a little trick I learned to "thicken" plastic. WARNING: I have used this technique a number of times, but not for this particular application. I have not tried this on any of my RF-602s as I either screw into the bottom of the receiver or use stroboframe shoe clamps. (But I may give this a try tonight)

Get a little clear fingernail polish and apply a thin layer to the bottom of the foot on the receiver. Let it dry thoroughly before attempting to mount it in a shoe of some sort. Repeat this process again until the shoe fits snugly in your foot of choice. If you decide to remove it, you can usually peel it off with a razor blade. With use, it may come off by itself. Don't use nail polish remover, it might eat the plastic.

A word of caution, try the polish on a small part of the plastic first to make sure the polish you are using does not deteriorate the plastic. I'd use the middle of the inside of the battery cover. (But I've yet to have a problem)

Trigger: Canon RF-602 to 1/4" jack.
Flash: Flashpoint 320A mono

Monolight set up in living room. Walked outside, shot thru one thin wall, till misfires. Consistent in four trys to about 25 yds, the distance across a small swimming pool or banquet hall.

Issues: ~100% to 25 yds. Short of 300 ft specs but better than I had expected.

Had to do several tests because I started testing using my *backup* flash I've only used a couple of times this year. The *got flash* signal fired but the flash itself didn't. Good thing I tried it out! It needs further checking, probably easier handling also.

I had the same results with eneloop AAA as with alkalines. Except for longer life will any other battery (lithium?) make any difference? I tried to find a AAA size niZn for just a *kiss* more voltage, but amazon doesn't have them.

edit: Both my Flashpoint monolights work 100% with Cybersyncs. Don't know why the one didn't like the RF-602. Hmmmm.

Range Tested: 100 + feet. It was cold out!

The only issue I've seen so far is that sometimes the Zeikos flash unit won't wake up. But that is more of an issue with that flash unit. Sometimes it won't even wake up while on the camera. ??? New batteries in the flash seem to help. So far so good. I love using these little buggers. And for the price, For get about it! They get tested for real this coming Friday night at their first Basketball game! We'll see how the do there. That's really why I got them.

Max sync 250

Haven't tested max distance as I'm just playing around with them indoors.

Wakes the Canon strobes from standby.

Compared to my old cactus/pt-04's, these have been very consistent.

Also if I put the receiver on my 580EX II, I can then just use the 580EX II as master to control the 430EX as slave (without receiver) and have the ability to set the 430EX manual power from the 580EX II. I can't recall if the old cactus/ pt04's allowed that since I didn't use the shoe mounts then.

"Sometimes almost" at 1/200
"variable" at 1/160
Reliable at 1/125

Needless to say I'm underwhelmed - and scratching my head. At 1/160, a couple of frames are good then the banding in one frame was just a sliver, in the next it was half the frame.

What I do know is that I was testing very near a bunch of wifi devices, wifi networks, dect phones and bluetooth devices. I'm going to test this in a field soon, with my iPhone in flight mode. See what happens.
On a PC cable, the 430EX will sync to 1/250

You guys need to try the half-press-on-transmitter trick to try to boost max sync speed.

I pointed this out to a photographer in the Yongnuo group who only got 1/125 sync with his RF-602 set and his Sony camera. With the half-press trick he got up to full sync speed of 1/250s.

I am able to boost my camera's 1/400s max sync speed to 1/640s.

Read the details here.

So? The poster prior to me doesn't seem to know about it, so I put a pointer in the spot where it would help the most.

Camera is supposed to synch up to 500
Max sync without banding was 800.
Totally blacked out banding at 1000.
Issues: none discovered

No, I didn't know about it - thank you. With half-press, 1/200th is reliable, 1/250th shows consistent banding.

So, either the cheap stuff is slow in waking up or the 5D2 triggers relatively late. Well, I knew I was buying cheap stuff. Reliability is very, very good though. No misfires yet.

Max Sync: 1/200

Fired all 4 flashes simultaneously without flaws. After a month, one of the transmitters just stopped working. A little while later one of the receivers stopped working after I tested it with a flash I was thinking of purchasing. These aren't the toughest units around, I guess.

Not that happy with these, honestly. Seriously considering PW's.

max sync - 1/200 (which is also what the manual states)

strange problem? (its not really a problem) - these are "have" branded rf-602's and when the transmitter is attached to the hotshoe it won't let me go above the cameras max sync speed. however, with a trigger purchased from the same seller one month earlier (i first bought rf-602's as a gift for someone, liked them so much i purchased a set for myself to replace my cactus v4), i can use any shutter speed i want (although i'll get banding above 1/200)
I have 2 receivers and one transmitter. Can i put a receiver on my camera, and one on the flash and use the transmitter as a remote shutter and flash trigger? I noticed when i did hook it up like that, the flash and the camera would both go off at the same time, but i guess the timing was off and the picture wouldn't capture the flash. Anyway to make it work for self portraits or somethin like that.

Pentax K100D, SB-900 (2), Pentax AF540 FGZ.

The banding (a dark stripe or band at the bottom of the image) has occurred with sync faster than 1/125 AND FULL FLASH POWER (at full power, the flash duration is the longest: 1.1ms for SB-900, for example). The banding has not occurred with sync up to 1/180 at lower flash power, or at full power when the flash has been fired directly from the hotshoe.

The banding occurs as the first shutter curtain is fully opened and the flash fires when the second shutter had already started to close, blocking part of the sensor. So the dark strip is underexposed due not being exposed to the flash.

It occurs because of a serious delay in propagating the wireless signal from the RF-602 transmitter to RF-602 receivers.

If there is the need to shoot at full power faster than 1/1/25 with RF-602, there is no solution rather than use another remote control (at least I can't thing of any at the moment).

max sync speed: 1/250, but when flashes are with half-power or full-power, i got a dark area on the bottom, so must use 1/200.

anyone got the same problems with half and full power?

your canon 400d's max sync is actually 1/200th - thats why you get banding at 1/250th.

I have just received a pair of RF-602 TX and RX, to add to my year-old TX and 2x RX.

There was a manual wih the new ones! And the 6.5mm connector is replaced with a 3.5mm one - much more useful. The Shutter Release cable for 50D etc did not have a clutch, as my two earlier ones have, and the plug sits very loose in the camera as a result. Not well done.

I tried an old RX with the new shutter release cable, and found that it would not activate the shutter. The second old RX did not work either. Both had been fine during the last year, used mainly for shutter operation. A flash would not fire using the cable, but would on the RX shoe, in both cases.

Inspection revealed that on one, the YN 3-pin socket had one pin (Earth) pushed back into the plastic. There was also suspect soldering on the wires. I reworked the soldering and moved the pin back into position and applied superglue. Then I inspected the new cables - the shutter release one had one of the three holes in the YN 3-pin plug only partly formed. That is what pushed the pin through to the back! Cleaned up the hole, and all worked well.

The second RX had the pins ok, but suspect soldering. When reworking, the earth wire revealed only one strand left - careless wire-stripping probably. Reworked the insulation stripping and resoldered. Problem fixed.

Apart from the blocked plug hole, the new units worked fine.

Now that I have two TX, I will use these more. I like to have a spare TX for emergencies, and to have in the pocket for testing. I also want to test interference using one channel for shutter an another for flashes. My Cactus RF616 series triggers interfered too much with each other to be practical in that configuration.

No problems at 1/90th sec
some intermittent banding at 1/125th sec

I have two cameras, three flashes, four transmitters and eight receivers.
Obviously I have not tested all combinations.

I just play it safe and shoot at 1/90th, I will use PWII's for high sync work
I received mine today and I did a little testing.

Camera: Nikon D80
Flashes: Two Quantaray QDC-900WA's, Two Quantaray DSZ PZ-1's and One Vivitar 333
Max sync: 1/200th - Banding at 1/250th
No problems as a remote for the camera
Issues: none - Tested 100% reliable @ 100 Yards outside with cars and light poles in the path.

I purchased a 1 transmitter with 4 receivers, plus I also have a extra transmitter and receiver on the way so I will have a total of 2 transmitters and 5 receivers. That will give me a backup transmitter and a receiver for each flash.

It took almost 1 month for them to arrive, so a little slower than normal. They were purchased from mr.studio01 on eBay.

Canon PowerShot Pro1
Yongnuo 460-II at 1/2 power
Max sync 1/4000 (the camera's max shutter speed)
Tested five minutes ago from about 20m, through a double-glazed window

I still can't believe my eyes, even if I have the shot in front of me. I'll have to do more testing. I'll have to try all the receivers, at bigger distances, at lower flash power settings, etc. Now that I have something to compare against, I'll also re-check the speed of my old PT04TMs (dunno why, I never bothered until now to test the sync speed on this camera).

EDIT: Well, I was quite wise not to believe my eyes after just that sloppy test. I did some more tests today. Got confusing results, so I've started a new thread to discuss the issue.

As a side note, my older Jianisi PT04-TM syncs at 1/640 then, at higher speeds, catches some of the flash burst's tail (up to 1/1600 for a YN 460-II at full power, 1/800 at 1/4). Tested at about 1m of distance.

No problems using the transmitter on the hotshoe of one camera to trigger a receiver hooked up to another Nikon body for simultaneous shooting.

Have yet to hook up my sound trigger to the RF-602 transmitter, but have positive expectations. :)

Slightly disappointed due to loss of 1/50 s speed ...

camera: Sony A700
flash: Minolta 5400 HS
  1/200 s : ok
  1/250 s : half frame black
  1/320 s : almost whole frame black

... tried one trigger (meant for Nikon) set (with included batteries) with Minolta hot shoe adapters from Flash Zebra. Got same results with transmitter connected via Yongnou PC-PC sync cable (instead of being mounted on the camera shoe with adapter). Use of SSS did not make any difference.

I will update with results with Minolta 5600 HS D, two other receivers, & another trigger.
