You know what radio triggers need?

Yes
AF Assist.

I would really like a RF-602 compatible trigger with an AF assist beam right now.

Anything of the sort exist?
 
I'm not getting this...

You want an AF assist beam AND a trigger which is RF602 compatible....

So why not just get a flash with AF assist and attach a trigger via a sync cable ?

Because that would cost more AND weigh more.
All I need is the radio with AF assist.
 
Huh... AF assist is a beam that is on-axis to the camera. Once you go off camera, you have no ability to ensure the beam can be seen. Surely this is something quite specialised (hence why you can't get one)...

You realise that the transmitter sits on top of the camera where the flash usually goes? :thinking:
 
Doh... I was thinking you wanting the flash on the receiver sending the AF beam...
 
You will not find one because they are two unrelated and separate items hence my advice on how to do it using those two separate items. That is the only way you will do it other than Nikons CLS system but then that is proprietary and not RF602 compatible anyway.
 
My Canon EOS 10 (pre digital) had one built into the body of the camera by the grip...

Progress eh.....
 
I suppose you could use ST-E2 infrared trigger if you shoot with Canon.
It would be fine inside a room etc but might be difficult to trigger flashguns outside.
If you need only improved AF beam that is what ST-E2 night be used for, so not only as flash trigger.
that is as far as I understand it.
 
the only thing radio triggers need - is radio receivers!
 
The AF assist light is visible red light so it would have to somehow automatically turn off after focus was achieved or it would show up in the final image..

Get a torch :)

Yes, AF assist lights are made to turn off when you take a photo.
The RF-602s know the difference between half press and full press so it's very possible.
A torch would work if I had an extra free hand ;)
Which isn't always the case!

ok, how about: "You know what cameras need? An AF assist light"

Well, all this has told me is another reason I should have chosen Nikon -.-

I have a Nikon but regularly still use a big torch too! Trying to take photos in a dark alley at midnight etc...

I have AF assist on my Nikon too, but also regularly use a small LED torch instead as it's got more range. Cost a couple of quid, is under my control and I can use it for finding stuff in the bag at night too.

I have done some shoots in the pitch blackness, but I had some assistants to hold some keyring torches I usually carry around.

I won't always get the luxury of having assistants and I may have to hold my own light, which means holding a torch in addition to the camera and light becomes.. "difficult".

Surely it can't be hard to manufacture the RF-602 with a built in assist light like the Canon brand strobes? :P

It seems I'm the only one who would find that extremely useful :shrug:

I've got a small led torch (the type that comes on a band for wearing round your head) that attaches with velcro to my lenshood. It's just strong enough to assist af without contributing noticeably to the exposure :thumbs:

Alright, I'm taping a torch to my lens hood, haha.

That is very cleaver :) I used my mobile the other day when the light was failing, was pretty much pitch black in a forest lol I think from now on i'll pack a torch :).

Nope, not the only one at all :) And it would be technically possible too. Would be dead useful.
 
Sledgehammer to crack a nut....

The Eli Quadra has an excellent, battery friendly LED modelling lamps.
 
Hmm I guess it would be an easy hack to rig a light to the shutter trigger output of the rf602 receiver.. ideal would be to project some kind of a grid only like the flashes. Maybe I'll investigate over the weekend..

I s'pose you could put it in place of the green light, since that comes on when you half-press..
 
Ok just tested it.. it's not going to work out of the box.

- When the RF602 is used as a remote shutter release, it works with half-press, so when you press the transmitter button half way, the camera focuses, meters etc.. and when you press all the way, the shutter is released.

- If you're using it as a flash trigger, it will send the half-pressed signal whenever the transmitter receives a "ready" signal from the camera.. in other words as soon as you plug it in. you can then release and half-press the shutter button as many times as you want and the green light will never go out. only if you let the camera rest for a while, then the camera will put the flash to "sleep", and the green light will go out. I guess this behaviour is for waking up remote flashes that might have gone to sleep.

So in summary, shutter half-press and release is relayed correctly only if you're manually pressing the transmitter button.. not when signaled through the hotshoe. And there's a sync port on the transmitter but no half-press through those either..

I tested this with 3 cameras, 7D , 50D and 1D.. so I had one camera with the transmitter on the hotshoe and the other with the receiver as a remote release. Same results regardless of which camera was used in either position.

A bit disappointed really, was looking forward to hacking this for you :(

How disappointing :(

Thanks for trying anyway, it's the thought that counts :)
