Re: Sounds like sticky aperture blades

Well, I move the lever to fully open, and release my finger, and I see the lever snap back, but I can see the aperture is not fully closed.

The blades will never close completely because they set to the smallest f stop ~ f32 when removed from the camera body.

Check for dirty connectors on the lens mount as some sensors may not function properly if they are dirty.

Hope this helps!
