Why is it that if I change built in flash setting on camera to ETTL, the flash fires when I stop down (which I thought fixed my problem) but the photo is totally under exposed?. I thought the yn560 is a fully manual speedlite.

You are mixing Canon's coded light pulses with Yongnuo's simple optical slave system, and they are not compatible. The YN-560 is firing when it see the series of flashes from your camera but it is either firing too soon or too late to be visible in the photo. (probably too soon)

When you change the aperture, the coded light signals must change as well so that probably explains why you are getting variable results.

Thanks CCF. In regards to the high key shots, I have been playing around today and have run into a problem. Using my 24-105 with the yn560 works fine at the widest aperture-f4. The problem is that if I try to stop the lens down at all, the yn560 will not fire at all. I tested this with my 50mm 1.8 and got the same result, fine wide open at 1.8 but stop it down at all and the yn560 won't fire. I played around with shutter and iso settings but nothing changed.

Am I missing something here?

Thanks

Im not an expert but I don't think aperture setting would have something to do in firing a slave flash -?... RF 603s are your best options I guess.... I do have the 605s and 603s and I enjoy using them, even with my strobes.
