I called Sony tech support again today to check on the status of the vignetting problem and got the following info:

-I was sent the attached pdf memo from Sony discussing the problem.

-I was told that Sony support is expecting pre-paid shipping labels that will be sent to owners of cameras exhibiting the problem. These labels will ship the camera off to Sony for re-alignment of the lens. The person I spoke to said they were expecting the labels this week and would overnight them to owners.

-He took my name, address, email address, and s/n. I received the attached memo a few minutes later.

So...if one has a camera with the vignetting problem I would make sure Sony tech support knows about it so they can send you the shipping label.

To our loyal Sony PMW-EX1 Customers:

Since the launch in November, the PMW-EX1 has been received extremely well within the
market with a huge level of order commitments and very positive feedback from customers
using the product.

Sony regrets to inform you that there have been a small number of reports of a specific lens issue
with the camera, which upon further investigation by our engineering team, has been identified
as ‘unbalanced light falloff’ at the edge of the picture. The cause of this has been identified as
being a result of a mis-alignment of the center of the lens and the light axis. Sony takes such
technical matters very seriously and although this issue has only been seen on a very small
percentage of the units supplied worldwide, Sony has implemented a full review and
modification of the manufacturing process in order to alleviate any re-occurrence of this issue.
Sony will re-align any camera exhibiting the symptom described above at no charge to you at
the highest priority. If your camcorder exhibits the symptom described please call our Product
Operational Support Center at 1-800-883-6817, option 2-5-2 for advice on how to proceed.
When calling, please be prepared to supply your camcorder’s serial number, as well as place of
purchase.

Sony would like to thank you for your continued trust in our commitment to you as your vendor of
choice when investing in high quality professional video tools, and for your patience regarding
this matter.

Thank you.
