It'll probably end up in Indonesia! At least I know which one to look for :)

Hello, when you yuse a 35mm adapter, is cheaper when you "take the distance of the object and set it on the focus ring".

Observation on Vignette Problem
 

I took a clip (X02_0039_01.MP4 - indoor tennis) that was posted on this forum and played it in slow motion with the VLC player. There are a couple of places where you can clearly see the problem in the upper left corner. It shows up most prominently when the camera begins or ends a fairly rapid pan movement. It appears that the OIS is on, and is creating the vignette by trying to compensate beyond the capability of the lens. That's my best guess with the limited amount of video available.

If anyone has tested their EX1 and found no problem, it would be nice if they posted here so we can see the magnitude of the vignette problem.

Possible, but can you provide the actual frame grabs. This type of info really doesn't mean much to anyone without supporting it.

May I please have the link to the tennis footage? Thanks.

It's gone...
His host shut him off.

Thanks Steven. I hope someone has permission and puts up a mirror...

*sigh*

This is exactly the reason why I offered to host it for him here on DV Info Net in the first place.

It's really too bad for everyone that he wouldn't take me up on it.

*shrug*

Thanks Chris,
I'm not sure why he was hesitant with your offer.

Since he lost his host, maybe he'll change his mind

I have posted two grabs of the tennis clip a couple of posts before.

Speculating further on the OIS thing, I must admit when I first read it has just ON/OFF settings (rather than the Standard, Soft, Hard etc) I thought Sony was compromising on this for whatever reason - now we can guess the 77mm lens might be just too tight for 1/2" chips...

If this is true, I wonder what Sony is going to do about it. And how long we'll be waiting!

But nobody ever answered my question: does it also show without the lens hood attached? If it's the lens hood vignetting, setting up the new moulding for a bigger one could be the simplest solution! Much simpler than designing a whole new, 82mm lens...

If this turns out to be the case, it could mean a VERY long wait, right? Surely they won't just tell us to deal with it?

There was a lot of controversy over the 25p capability of the V1 in PAL countries at this time last year and we were told to more or less deal with it.

I hope Sony really, truly fixes this to the best outcome.

There aren't enough users with cameras out there to test if there really is an actual problem.

Although I still don't have mine, I am hoping to have some free time on Monday to go to my dealer and really put their demo unit through a thorough test, including 35mm adaptor test.

Perhaps we could hear from all the EX1 owners out there if they have come across it or not...

Hi Piotr, I tried removing the lens hood assembly / matte box and it makes no difference, it's not that.

I don't know enough about the way lenses function to fully understand what this problem involves, my guess is that it's more than just making the lens barrel wider though. I would have thought that lens element placement / shape will be the primary control over presenting a correct image to the sensor block, either that or the distance between the lens and the sensor block itself. I guess this could be solved by enlarging the visible area presented to the sensors with optic placement, I can't imagine Sony would go back to fujinon and ask for a bigger lens though.

Adam Wilt mentions in his review that he was told by Sony that the vignetting in the camera he tested was caused by the auto-focus system, as that's the only real comment we've heard about the problem that comes directly from Sony it's more likely that this is still the issue, and we still don't know if there really is an issue. It would be great to to hear from other owners, but we only know of four cameras delivered so far.

Paul.

I have yet to see anything posted other than Paul's camera that actually "really" shows a vignetting problem. I've seen nothing convincing
from the tennis footage and the guy that owns the camera has never mentioned a problem.
Several days ago I asked him when he gets a chance to run the test.
He said he would when he finds the time.

My guess is there might be a mechanical adjustment that might be out of spec within Paul's camera.
I can't imagine Sony would of let a problem like this released. This is a defect, or a misadjustment.
IMO, this problem is not across all EX1 cameras.
