Plasmat Roland 6x4.5 was introduced in 1933 by Plasmat (renamed as Rudolph & Co. Kamerabau in 1936) located in Berlin, Germany. Roland is a 120mm film rangefinder camera which film sized 6x4.5cm and 16 photos can be shot per film roll. The initial fast shutter speed of the camera was 1/250s, however, it was later replaced by shutter of 1/400s so as to produce a crisper image of a moving subject.
On the other hand, Roland was equipped with the Plasmat 70mm f/2.7 lens that constructed by ZEISS’s former Director of Optical Design, Dr. Paul Rudolph. The Plasmat 70mm f/2.7 lens was one of the 120mm film rangefinder cameras’ lenses designated after Dr. Rudolph’s transfer to Hugo Meyer. Some of Plasmat lenses were even used to film cameras including Kino-Plasmat, Makro-Plasmat. In particular, Roland’s Makro-Plasmat 70mm F2.7 fast lens accompanied with 6 elements 5 groups mixed structure (Gauss and Plasmat), deliver excellent quality of imaging.
The lens coupled with rangefinder, so users can easily turn the lens ring to focus. In addition, Roland's telescopic lens is a value-added design for users due to greater convenience and better protection.
