Chad...............

Did you do a back focus on the camera when you first got it?

Ryan,

I was told that I didn't have to adjust the back focus unless I had problems. This was the first problem that I have had with the camera. I did read a little about setting it up and its going to be the next thing that I try.

Chad, checking backfocus is easy, on all my pro lenses you simply setup a test image

http://www.dsclabs.com/

http://www.bealecorner.org/red/test-patterns/\

zoom in and focus...zoom wide and if out of focus (manual focus)

loosen the backfocus screw and adjust

p.s. shoot wide open and Don't over tighten( I onced cracked my back focus ring on a jvc-3)

also a long time ago on a old tube camera my backfocus screw loosened up on me and didn't realize untill 10 minutes later, so it is good to know where that adjustment is and check occasionaly

any chance of uploading footage with multiple flashes going off
thnx steve

Yeah...... the lens comes attatched so i would have assumed that you didn't have too............ but it's worth trying anyway.

Edit:-
Oh........ and i'm pretty sure that a test pattern comes with the camera..... did yours?

Both of them came with the test pattern. A previous post suggested that I should remove the UV filters and see if that helps. We have 5 weddings this weekend, so I'm gonna give that a shot. I'll keep you guys updated on what happens.

That looks like the autofocus went haywire, has nothing to do with back focus.

Hello,
There is no backfocus ring on the Z7 lens to adjust the backfocus.
We have just to focus in tight shot then adjust the focus in wide shot.
It's clearly impossible to adjust a focus on the shorter focal lenght because the focus stands still from 2m to infinity... So the auto mode seems to be the more appropriate.
On my own experience, I 've never achieved a correct back flange on my Z7, using manual or auto mode.
