Zeiss-Ikon Nettar 518/16 brand_Voigtlander ) with pretty decent buildThe Zeiss Ikon 518 16 is a compact folding camera that shoots 6x6cm exposures on 120 rollfilm. It's equipped with a scale focusing 75mm f4. 5 Novar Anastigmat lens in a five speed Velio shutter. This Nettar is in excellent condition, with only minor cosmetic wear. Lens is clean, bellows are good, and the shutter works well through the range. About as close to pocketable as medium format gets.
