I actually stopped just short of slicing the box and thought "Hey, I better check for vignetting before I do this". Did you already mail in the UPC? If so, I'd say call B&H and explain, then call Sony. I have to call them today and sort it out, but I'm sure Sony can send it back to them with a new UPC.

Well, now I don't need to be concerned about sending my first EX-1 (from which I had cut the serial number to obtain the "free" 8 Gb card) back to B&H (referred to two posts above, just prior to Sean's kind reply).

I received the replacement EX-1 from B&H today, put it through its paces, and it is also mush regarding backfocus, at Clear, ND-1, and ND-2. So the replacement, rather than the orignal is going back to B&H. The serial number of the latest was 104003. The software version on both the old and new was V1.03-0351.

Again, B&H certainly tops out on customer service! Since I have a shoot coming up in NYC in early May, I may try the FB adjustment and see if that does any good in each of the 3 ND settings, and if not, call Sony immediately for a software update and adequate repair. Thanks to you all for the tremendous and learned amount of information about this camera!

But what is the point with the vignetting issue ? :)
You're right, it has nothing to do with vignetting... but backfocus issues are also non related to vignetting! I though that it was not the wrong place, since all three issues are related to the lens of the camera.

Maybe this thread should change his title from "Vignette problem" to "Lens problems".

That's weird. My s/n is 4700 and I got the new FW number.

Well the sony tech says based on my pics he is not sure there is a problem with my ex1! Please take a look and see if I just need new glasses.

He gave me an 800 number I called and they say I will have to pay shipping to send it in. Have they done the same for you?

Chuck,
its pretty obvious that your camera has a problem. Thats the typical backfocus problem. No new glasses needed ;-)

Guys tell me, it's obviously soft - but where is it's focal point now, at min. dist. or nowhere? It looks like someone smeared a thin film of vasoline on the lens...

Back focus is out.
Do you have the latest firmware?
It's been shared to several that this firmware is needed to adjust the problem.
The image contrast is different, but it's still soft.

Just recieved a message from Sony tech reports that the latest firmware update does NOT solve any backfocus issues that he is aware of but that they will recalibrate the lens after performing the update..

"To my knowledge the firmware update doesn't address your issue per se
but it may still be a good course of action. After updating the firmware
they will also re-calibrate the lens. "

Guess it will be a crap shoot but something has to be done.

I will send it out and see how it comes back.

Not knowing Chuck's settings, it _could_ be that engaging ND filters and opening the iris accordingly, narrowed his DOF enough for the scene to stay out of it (with the focus plane being very close, or in infinity).

Camera set up was as follows

iris wide open shutter used to stop down the light for non ND. Zoomed to center of tree trunk, focused and zoomed back wide with iris wide.

Then I switched in ND filters and changed shutter to a lower setting for
ND1 and then off for ND2.

Ach, OK - so you basically didn't open iris while engaging ND. My theory is not valid - back focus is bad.

Chuck,
I have read several responses between this board and another mentioning that their back focus issue was fixed. So, if it's not the new firmware, it's something else.

According to Adam Wilt, the back focus adjustment in the service menu appears to only correct back focus at a given condition, ND OFF, ND1 ON, or ND2 ON. He mentioned it will only correct for one at a time.

Having said that, my camera does not have the BF issue regarding ND position. If it does, it's real small and not that noticeable.

Steven

I am wondering if only the cams that had the vignette issue also suffer from the backfocus problem. My cam was sent back in early Jan for that problem.

I just completed the back focus adjustment myself because I'm not able to have Sony do it until the 2nd week in April. Thank goodness I only live 15 min. away from our western Sony repair facility!

The back focus adjustment seems to have worked. I did it without any ND filters then did another test outside using ND1 and the image does appear to still be a little softer than with ND Clear, but even with the ND filter it now seems to be better than it was before the adjustment.
