I bought these - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150600182426
a week or so ago, set them up, and im faced with two problems:-

1: half of the image is black and half is lit up, now i realise the mechanics behind this however I am unsure of how to change the settings...

2: it doesnt flash everytime, even though my enviroment needs the flash everytime, it doesnt seem like the trigger is connecting with the reciever all that well, its a bit hit and miss to be honest.

Ive got a canon eos 40d, ive looked through the books, ive looked through threads on here and cant find the answer,

any help from you all would be really appreciated.

cheers

have you checked your shutter speed? Are you synching under 1/250?
Sounds to me your ss is higher than the sync speed so you are getting half of the frame dark, if I understood correctly your problem.

I have four of those and they always connect and trigger every single time, so far
 
not sure about the second problem, but the first is most likely to you using a shutter speed faster than 1/200th sec.
Try putting the camera in manual and setting ths shutter speed to 1/160th and see if that makes a difference.

I too use RF-602s and they work really well for me
 
Flash sync is almost certainly the problem. At full battery on flash and receivers I can get away with 1 200th of a second. As they drain I have to use slower speeds. I almost always use manual mode to avoid this.

Your flash won't fire again until its fully charged. If the light on the receiver goes off and the flash does not then that's most likely your problem. Charge-up gets slower as the batteries drain.
 
+1 for synch speed.. if you're in Av mode there's an option you can set that keeps the shutter speed at the synch speed. But with an RF-602 you should really be in manual mode anyway as there's no TTL capability. So keep the shutter at 1/250 or 1/200 or slower.
 
You need to shoot manual settings for off camera flash. Sounds like you are shooting at over 1/160th (on safe side) on your shutter speed.

You say you need the flash to fire every time. If you want it to be rock solid in reliability you need to be looking at spending more money on something like pocket wizards, although these are reputedly good triggers.

ok, you were all right about the speed, now im not getting that problem however the flash is still only firing once in about 15 shots.....

Check your batteries on the remotes/flash/sender and receivers
 
May be a daft question but what flashes are you using and how quick are you shooting.
On full power some flashes can take a few seconds to recharge ready for the next flash and a very long time if the batteries are low
 
im using a speedlight ex430ii
and it doesnt seem like a recharging time thing, its taking minutes not seconds in between flash's...
 
Try changing the pin settings. sometimes you get rf interference from other things around you.

Might work, if not smash it with a hammer while taking a photo then show us :) maybe do a hdr
 
ok, seems to be exactly 1 minute between flashs
 
Is it still making that whiney recharging sound? Does it have an indicator light that will let you know when it's charged?
Even if you think the batteries are good, change them just in case you have a dud. No point speculating on faults before you've done this.
 
The transmitter doesn't have an indicator light, but the receiver does. Connect the receiver to the flash without the transmitter on the camera and press the button. When the flash doesn't go off does the light come on (or change from red to green - sorry can't remember which it is) but the flash doesn't fire?

The transmitter seems to be a loose fit to the flash gun shoe, so always make sure it's pushed on fully.

Only thing other than that is batteries or channels used (change by using the dip switches on both). The transmitter battery I always take out after use. I found it was getting flattened by leaving it in.
 
Leon.. are you firing the flash full power? what batteries are you using?

Cheap batteries and full power flash.. could easily be recharge time, or the flash protecting itself from heat build-up if you're being trigger-happy with the shutter.


Please describe exactly how you have the camera and flash set-up (modes/settings) and how you're shooting. At the moment your description is so vague it's difficult to pick out what you're doing, and the best we can offer are our most likely guesses.
