Zeiss-Ikon Nettar 517/16 lens mount_Leica Thread Mount but it beats carrying aroundThe Zeiss Ikon 517 16 is a compact folding camera that shoots 6x6cm exposures on 120 rollfilm. It's equipped with a scale focusing 75mm f6. 3 Novar Anastigmat lens in a three speed Vario shutter. This Nettar is in good condition, with typical paint loss on some of the aluminum trim. Lens is clean, bellows are good, and the shutter works well. About as close to pocketable as medium format gets.
