Re: EX1 Backfocus Issues - I've sent two cameras back now

I think there is definitely an endemic problem with back focus on these cameras. I sent the first one I purchased back to Sony and they replaced it.

The replacement had excellent back focus on the clear filter, but filters 1 and 2 were soft. I've read several other posts that have had the same problem. Fortunately I found a post on the DVXuser.com site that at least shows you how to set back focus. This operation fixed or rather set, the back focus on all three settings and it looks great.

Open the maintenance menu, which of course Sony doesn't tell you how to find. Mark & Mary Ann Weiss on the DVXuser.com forum gave me instructions on getting to the menu. You get to it by pressing Menu sel/set and the Cancel buttons simultaneously.
Then using a back focus chart at sbout 9 feet distance zoom in and focus on the chart, then zoom out to wide with the aperture wide open. You can use the shutter to control the f-stop.

In the maintenance menu choose backfocus adjustment (FB).

When it finishes leave the menu, then put in ND 1 and do the same thing and then do it with ND-2.

Worked great on my camera.
