Talking about the old version 35-105, I had one before that had some
problem, the aperture does not close fast enough, if you stop down it
by hand it is okay, if you set the shutter speed at 1/30s or above the
aperture does not fully stop down during exposure. It was due to the
closing mechanism is linked with a spring not directly connected with
hard metal. Does your guy found the same problem?
