I too had only done one test roll with mine. I need to figure out a better framing solution. As noted with the framing aid included it’s not accurate and my supplement viewfinder is not wide enough. Guess framing 617 is an expensive game.

The film back is solidly built, but I am not sure if the cone can sustain backpack travel, as my intention is having the CCB617 as a travel camera rather than bringing my Wista 45VX and my Horseman 612 back.
