Lately seems I've been having a hard time balancing my lens. I had it tweaked perfectly using the 1d mark II with flash arm bracket; etc. with and w/o 1.4x tc (my 500 4.0L)
but with the lighter 40d i'm having issues. I connected the plate to the lens as directed, but it seems I run out of room sometimes. and rather than spending a few minutes, I'm there for a while trying to get the **** thing to balance.
For some reason, I used to be able to get it to stay fixed in any position I put it. Now when loosened, it doesn't.
it also doesn't help that I can't find the instructions that came with the head (doh!) ...
also, the flash bracket ... is it better to lock it towards the back or the front of the plate? i've been locking it on the back of the plate to help the balance cause if in the front, I run out of room to slide the lens.
suggestions? what should I be doing?
