Flash synch problem with 250mm C lens


New Member
I was recently trying to take a polaroid with my 250mm C lens in a studio setup. When I pulled the polaroid, it was straight black... when I used the old 120mm C lens for the same shot, the polaroid came out fine.

I just got this lens and this was my first experience with it, is this a common problem with old C lenses, it appears to be fine other than the flash synch problem, the shutter fires, and the shutter speeds all sound pretty accurate.
