Per my email to you, I thought I fixed this -- you may need to log out and back in again -- if you don't see a "manage attachments" button below the text input area when making a reply, please let me know by email. It may have something to do with forum permissions in that case.

Here are two full size grabs.

The soft one is deep focus, the sharp one is close focus.

Don't be alarmed by the noise - I had gain maxed and the 6-stop ND filter on to home in on a good wide-open exposure.

It beats me how something like this could have passed the QC.

Eric, judging from those stills it also exhibits a blueish hue on the right side. It though I saw that on Paul Joy's shots although it was on the left.

Try OIS off.
I thought Adam Wilt believe the issue was related to the focus mechanism rather than OIS.

Eric you are right, my monitor is underscanned. Not by much though, not as much as the safe area on the EX1 LCD outlines. At least using the component inputs. Although the camera's LCD is small, I see no issues. I will capture a test soon.

Eric, you examples are not as bad compared to Paul's.

I wonder if this issue is similar to the inconsistency we found in the HVX imaging blocks not always being centered on the lens. This didn't show up until we started focusing in on 35mm adapters on the HVX.
In the Panny case it sounds like it was due to manufacturing tolerances not being strict enough. Similar issue perhaps?

OK...
Here's the deal.
I've got it... vignetting
Now I'm wondering if they all have it and some are not looking hard enough for it.
Hmm...
Is it bad enough to return, will it effect normal shots, it's hard to say.
I know one thing, Sony is going to have their "ear full" on this one.
This should of NEVER left QC!

Sorry to see you've got the same problem guys, I really hoped mine was a one off . Please let us know how you get on if you go the Sony support route, I'm interested to know if Sony are going to fix it or just decide that it's within tolerances.

what a shame!

Paul.

Thanks Paul.
Good question.
I'm not sure if I want to give the camera up.
When they figure out how to address this situation.
I will send it to them.
It's now aparent, you just can't order another camera.
I believe the percentage pf cams with an issue here are probably 75%.
I have a feeling it may be higher as everyone gets theirs.

Here's a quick look at my vignetting.
Please overlook focus and white balance. I was focus at a far distance near the end.
Also, to make the vignetting more obvious, I only reduced the image brightness.
It only happens between 10mm - 25mm.

Yours doesn't look so bad Steven, it seems the sensors are biased to the right side and hence only showing the effect on the right. Eric's on the other hand looks almost as bad as the one I had.

In both cases the OIS will definitely make it worse, I looked over some of the hand held footage I shot and I can see the vignetting moving around in the corners.

I didn't go through this entire thread but has anyone talked to Sony about this yet? Has there been a response?

I don't have one to play with, and I hate to toss in an idea where I can't test it myself but...

my question is... could this be sensor heat noise??

The way I check the Canon 1Ds is to just put the cam on a tri-pod, open the shutter for a couple minutes with the lens cap on and let the camera take a picture... The picture comes out as black and if the camera suffers from
thermal noise the noise shows up as a purple vignett where the sensor is
suffering from heat....

If the sensor is OK then the picture just stays as black .....

Just maybe a test needs to be done on the EX1 to make sure its not thermal
related...

might even slightly warm the camera up with a hair dryer from about a foot away from the camera during the test??

I captured it after the camera was only on for two minutes.
I don't believe it is due to heat.
