----- Original Message ----- From: Vic Subject: Tokina AT-X 90/2.5 acting up
Vic: My Tokina 400mm did the same thing to me a few years ago when we were in Kodachrome Basin. I pulled the lens mount off and the aperture worked fine, so I put the mount back on, and it has continued to work fine. I don't know why. I do know that if the lens has an A setting, I wouldn't be pulling the mount off. A series lenses have small explosive charges in them that detonate when the mount is removed, sending small bits of shrapnel like lens bits all over the place.
