Vignetting on one side
on Dec 14, 2011 at 8:20:58 pm

I was filming something recently and I noticed some vignetting on the ride top and bottom corners. This was using the AF-100 with the 14-140mm lens. Later I switched out the lens with a 50-250mm and still had the same effect while the 14-140mm did not have this effect on another AF-100. So fairly certain it is the camera.

When I tried it hours later it disappeared.

Anyone know possible reasons for this and if I should send it in? Only three months old.

Sometimes the ND Filter wheel will get bumped and be turned just slightly creating the same effect. I've had it happen a couple of times when changing lenses on the AF100.

Agreed, the ND filter wheel is the likely culprit.
Especially if it was not there a while later.

Gotcha. Thanks for the help. Ironically I asked my boss and she said the same thing. Then she found my post and your answers she forwarded them to me as a "see, I was right." Well played boss, well played.
