Behind the scenes pic from last weekend's testing. Mamiya 645, 5DII, Canon Canonet QL17 GIII, Olympus OM-1N, Olympus OM10
I just acquired another Mamiya 645. The one I have has some issues with the cable release adapter. While I was sitting there waiting for the exposures, it spontaneously started over, so I have no idea how long its exposure was.

Added Ektachrome 100G and 100VS to the testing pool.
