Mamiya Press, good selection of lens, the Universal Multi Back allowed for 6X4.5, 6X6 or 6X9, with ground glass back and extension unit could be used for close ups, or used with 6X9 sheet film. Designed to used hand held. The Cs, I know folks rave about Rolli lens, but the TLR lens were top of the line, the 80mm was 2.8 and unless shooting with very high resolution film was as sharp as needed. Built in bellows, interchangeable finders, although the Konica Omgea Flex had interchangeable backs was almost impossible to use in landscape mode.
