Glass · Medium format

Cameras for 120 film: the Hasselblad, Mamiya and Pentax systems, with their leaf-shutter and focal-plane lenses. 156 families across 3 systems.

Mamiya

Sekor glass for eight mounts that share a name and nothing else: leaf-shutter lenses for the RB67 and RZ67, the 645 bayonet and its 1999 autofocus successor, the paired lenses of the C-series twin-lens reflexes, and the rangefinder lenses of the Mamiya 6 and 7 that reviewers still put beside anything made for 120 film.

Hasselblad

Everything Hasselblad built for 120 film: the 6×6 V system from the 1600F of 1948 onward with its Zeiss and Schneider glass, the Ross-built military cameras of 1940–45 where the company began, and the autofocus H system of 2002.
