Anyone have Pentax 645 FA 300mm f5.6 lens - need dimensions
« on: October 28, 2025, 04:56:40 pm »
I just ordered a used lens from Japan and it will ship to NJ. In advance of it getting here can anyone measure the lens barrel diameter near the mount? I would like to retrofit a third party or another lens maker's rotating tripod collar. I will be using this lens with a Fringer auto focus adapter on a Fuji GFX 100S.
Thanks in advance
