I just developed a Medium Format Pro 160S which I shot with an old Franka Solida II and boy that lens is sharp! I am also extremely happy with the outcome. I was curious to see how would a 60?? odd year old camera would perform. I used a Kalimar light meter and ran a roll of 160S in the summer.They still need some cleaning (scratches) but here's one:

Again, I kinda extended the processing time as the concentration of developer was slightly less (yes, I still haven't got those storage bottles so I get rid of the chemistry in the end

) but the grain is very very fine and the colours are amazing. I am happier with these than with the ones from the 35mm even though I only got about 3 good ones, as the Franka has no frame stop, so I ended up overlapping a few.
