SWC camera – a super wide speciality
The Zeiss Biogon® T* 4.5/38 CFi lens is a super wide angle lens of stunning performance. Its rear element is located very close to the film. Therefore it is not possible to use this lens with the mirror of an SLR viewfinder moving between lens and film. To make the outstanding performance of this lens available to demanding medium format photographers, Hasselblad built the SWC camera, a special very compact camera body which integrates this Biogon® super wide angle lens, equipped with the battery-independant Prontor CFi central shutter, into the Hasselblad camera system.
The legendary, high-performance, super wide-angle lens in the Hasselblad superwide camera
- Super wide-angle images, free from geometric distortion
- Small, light, high resolution
- For architects, demanding interior photography, industry, journalism, travel, aerial photography, particularly detail-rich snapshots
90 degrees angle of view, a focal length only half the diagonal of the film frame, produced with an almost symmetric lens design of surprising compactness, featuring the typical advantages of symmetrical lens designs: distortion is extremely well controlled, and so is color correction and image field flatness. Combined with extreme precise manufacturing these properties make for an outstanding wide angle optic with high resolution, an excellent documentention tool. This is exactly what is needed in aerial mapping photography, a field where Carl Zeiss has played a leading role worldwide for almost a century, hence the expertise to design and manufacture such an outstanding high-performance lens like the Biogon® lens. Since the last vertex is located only 18.8 mm away from the film plane, no viewfinder-mirror can be used between Biogon® lens and film. So Biogon® lenses cannot be used with SLR type cameras. On the other hand is the performance of the Biogon® lens so outstanding, that this lens is worth a camera body of its own: The famous Hasselblad Superwide Camera SWC, the state-of-the-art wide angle device in medium format for almost 50 years and the premium choice for those who demand the utmost in wide angle performance on earth and in space.
The Hasselblad SWC with the Biogon® lens is a powerful and fast tool for architecture, demanding interiors, documentation, industrial photography. Combined with current high resolution films the SWC and the Biogon can easily replace view cameras in many situations: It is much faster, smaller, more convenient (no cassette loading in the dark) and more portable; film and processing are much more economic. With the focusing screen adapter 41050 precision focusing is possible down to 20 cm in front of the lens. |
