David,
Oooh! The Contaflex TLR. A magnificent piece of engineering. A 35mm
TLR with interchangeable taking lenses and a fixed focal length viewing
lens. The Albada finder alone was worth the price of admission.
Zeiss used that type of sports finder on the Ikoflex III, which was the
only real competition that the Rolleiflex ever had.
