What is the difference between the Kiev 60 and the Kiev 645 cameras?
As the photo below shows, the Kiev 60 camera is a 6×6 cm (square) format taking 12 exposures on a roll of 120 film while the Kiev 645 is a 6 x 4.5 cm vertical format taking 16 exposures on each 120 roll. Otherwise these two kits are identical: both synching at 1/30th of a second (and slower), both accepting Exacta 66 and Pentacon (Carl Zeiss) lenses, and both shooting 120 film exclusively.
