At least that's the way it worked when I tried my Vivitar Series 1 600 on it. (That was before the 1.1 version of
the firmware was released).

I thought I read somewhere that it was possible to use fully manual lenses on the istD. I'm trying to use my 400mm mirrored Sigma with it. I thought it was possible to just manually set the aperture on the camera, but I can't get it to work. Any ideas on this or am I out of luck?
