I made many medium format cameras, but this one is my first 35mm format. Film is advanced from take off canister to take up canister with flipped spool. Two turns (+/-) or 15 clicks. Frame size is 24x65mm, focal length 40mm, 0,2mm pinhole size. Loading/unloading of film is easy- only threated disc and wooden element from the bottom of guides need to be removed. Samples i will upload in B&W section
