Problem Focusing an EX1
I have 2 sony EX 1 Cameras – and just recently i am having a very dificult time getting my #2 Camera to be in focus – is there a back focus on the ex1? I cannot depend on it being focused though it looks focused in view finder and foldout screen? any ideas? Any known problem?

Yes, there is a way to adjust the back focus (called flange back adjustment) on an EX1. You need to get a proper test chart first though. Then you need to mount the chart on a wall and your camera on a tripod. Then you need good lighting.
Then turn on your camera, press and hold the Menu and the SEL/SET buttons at the same time and then press the CANCEL button. In the viewfinder the Maintenance menu will appear. Scroll down to “FB Adjust” and hit enter. The letters “FB” stand for “Flange Back” which is the official terminology for adjusting back focus. Make sure your camera is in full auto focus mode. Zoom in to the test chart so that it fills the screen and then hit “Execute” in the menu. The rest is all automatic and takes about 15 seconds.

The flangeback adjustment process is a lot more involved than that – the full answer is on Don’s website, though. Sorry, Don!

The Flange Back adjustment procedure described on my site is for an EX1R only, which is quite a different animal than a straight EX1 which is what the O.P. asked for.

I should’ve known better than to doubt you!
