Hi there

I am trying to get my Canon 5d MK111 bodies to fire my Lencarta Safari 600 Classic battery lights, using two Yongnuo RF603C transceivers. The two transceivers seem to talk to each other, as when I press the fire/test button on top of the transceiver, it fires the lights - but I can't seem to get it to fire through the camera.

I have a PC sync cable and have tried plugging it in to all ports that look like it might fit!

Can anyone tell me if the RF603C transceivers are compatible before I go nuts?!

Thanks!

Have you tried syncing them at say 1/160th 1/125th?

I don't see how the shutter speed can be relevant here. I had a detailed phone conversation with the OP this morning. The problem seems to be a bad contact between the camera hotshoe and the trigger. Neither of us can think of any reason why this should be so, her post is to see whether anyone knows of any conflict problems
 
I don't think its a compatibility problem, have you tried shorting the hotshoe with a paper clip? That'll tell you whether it's a fault with the shoe on the trigger or if it's the camera hotshoe.
Can you fire a flashgun OK on the hotshoe?

If the answer to both of those is Yes, then it's possibly a physical fit thing.
 
I had read that sometimes the 603 can be a little slow on the 5Diii and people got round it by dropping the shutter speed down. Granted others said it worked at 1/200
 
I noticed a lot more misfires and lots more shutter sync problems when I switched from 602's to 603's using the 5Dmk3.....I have six 603's and every combination of those six triggers have shown faults. No idea if more recently made 603's are any better than older ones as I bought my 603's straight after they were available in the UK.

I'm going down the ST-E3 route. The 603's will mock me no more!!
 
Hmmm, interesting, thanks guys!

The camera hotshoe itself is fine as it will fire my speedlites each and every time when they're mounted. I've also tried to use the 603s to fire speedlites remotely as well as the Lencartas, and the two transceivers just won't talk to each other when I press the shutter - and actually when on the speedlite, they won't even talk to each other in test mode, which they do when on the Lencarta. I'm firing at 1/125, so not too fast.

Maybe it's the shoe on the trigger in that case, as Phil V suggested. More investigation!
 
i was aving major issues with my 603's in the past. miss firing etc not working right.

turned out to be the batteries even tho the led's are on they was playing up.

changed them worked spot on 1st time.

also make sure they are all on the same channel under the batteries?
 
Good advice with yongnuo triggers is to throw away (I mean, recycle!) the batteries they came with immediately as they are invariably cr*p, and replace with duracell/energiser. Interesting to hear about 603s being less reliable than 602s. My duracell powered 602s are very reliable indeed (but I'm using a 5D II, not a 5D III).

i've had this issue in the past with yongnuo triggers and most of the time it's batteries like Simmy said, make sure the batteries are charged fully up.

Don't use rechargeable batteries in triggers, especially the newer 622s. They have sensitive low battery warning that 'trigger' at not far below the standing holding charge of rechargeables.
 
A PC sync cable won't help, there is a different little jack cable that goes from the 603 to a small socket on the camera i think. This is how it works on an old 1000d. One 603 on camera with this small mike jack like cable connected to the camera, the other 603 anywhere you like with a pc connector between it and the light.

As in this kit http://www.amazon.co.uk/YONGNUO-Wir...F8&qid=1398114711&sr=8-5&keywords=yongnuo+603

I think I got that right ??

I'm using Eneloop rechargeables on my 622C's with no problems. I just recharge them at the same time I recharge the flash batteries, also Eneloop.

The ST-E3 infrared is fine for most situations, but not as versatile as a radio trigger. Infrared needs line of sight and may not be so reliable in bright sun light.

The ST-E3 is radio, not just infrared. (y)

There are several reports of users having sporadic problems with 622s that have been solved by using non-rechargeable batteries and their higher holding charge. YN don't recommend them.

But hey, it's your choice.

Still getting used to this Chromebook chicklet keyboard thingy. Might need a heavier touch on the CTRL key. Weird bloody things....

Ooh .. I sit corrected .... thanks!

But somewhat confusingly, the 600EX-RT gun supports both radio and optical mastering.

Indeed. <dream>Wouldn't it be nice if there was one standard system all brands support.</dream>
