Vignette problem

Phil Bloom posted this as part of a series of frame grabs.

In the upper left you can see the vignetting.

Maybe it's just my eyes but I also see a slight grey/blue cast on the side of the vignette and that's something I've seen to varying degrees on some of the other exhibits as well as on the camera I checked directly.

I'm beginning to think all the cameras exhibit this although apparently not with the same setup and severity.

I do wish Sony what say something even it were only, "We see it and we're looking at it."

I'm stating the obvious, but the more cameras they send out, the greater costs to them to fix, assuming it's fixable.

Called the Sony number and reported . I was the fifth person who's called the guy I talked to (Lou). He assured me that the Sony engineers were on this, considered it serious and would fix it. He said it was not on all the cameras.

Do they ask people to send back the camera or . . . ?

Hi

The indicated that the will contact me via phone when they have a solution.

Thanks Chuck. That's an important bit of info for all of us.

So it seems the best course of action is when you get your camera, check it out, notify Sony, hang tight.

BTW did you send them a test clip or frame grab or did they just take your word for it?

FYI, I saw a faint example of vignetting on the EX1 I had this weekend using the testing procedure recommended here on DVinfo, but haven't seen any sign of it so far in any footage I recorded under normal circumstances. For my purposes I wouldn't call this a significant problem, but I would want to know what Sony's response is going to be if I was planning to buy the camera.

Chuck Wall · December 3rd, 2007, 03:10 PM

They had other reports and took my word for it. They did let me know that Sony Japan was working on the issue. I agree with Kevin, just doing some testing I did not even notice it with moving images and various zoom settings. I suppose if I were to sit on the "bad" spot I would pick up on it.

Wow - and here I was all excited to replace my beloved JVC 100... Not yet baby!

All joking aside, is this a worse problem then the SSE on the JVC? I still get the effect every now and again, but I work around it and get as much as I can out of that cool camera. But still, on paper, the EX-1 would appear to be the better camera...

But this vingetting would appear (and please correct me if I'm wrong) to be exhibited under almost all types of shooting conditions, thus a much worse problem then the dreaded SSE.

Am I wrong about this?

For me it is only during the middle range of the zoom and while it is there it is not seen on either my plasma or lcd HDTV. If I can get some time I will post a clip with the zoom in the most noticable position.

John,
the EX1 vignetting issue is seen between 10-25mm focal length at or near open aperture.

John Vincent · December 3rd, 2007, 03:55 PM

So, it's kinda similar to the SSE problem in that it seems to be previlent on some cameras and that it (generally speaking) only happens unly certain conditions.

Will it always occur (with the cams that have the problem) in that 10-25 mm range?

If it has the problem, this is the focal range it's been seen.
Oddly, we have not seen the problem at full wide.

Craig Seeman · December 3rd, 2007, 04:12 PM

Doesn't this seem wider than 25mm?

My vignette is worst at 10mm.

That shot could easily be 10mm.

If you read the earlier postings on this thread, this is all covered. There are also several frame grabs of "typical" vignetting problem (including mine).

Eric Pascarelli · December 4th, 2007, 10:43 AM

My dealer just wrote me and told me that Sony had "figured out" the vignetting problem, and that he had no further information at this time, but would let me know when he did.

FWIW.
