Carl Zeiss Biogon

A lens with an angle of view so wide that it can capture very much of the life around us in a single frame – this is what the name originally means.

Typical Biogon® lenses:

A focal lenght 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 documentation tool.

Biogon T* 4.5/38 lens for the Hasselblad SWC Superwide Camera.

This is exactly what is needed in aerial mapping photography, a field where Carl Zeiss has played a leading – even revolutionizing – role worldwide for almost a century, hence the expertise to design and manufacture such an outstanding high-performance lens like the Biogon T* 4.5/38 lens, invented by Dr. Ludwig Bertele at Carl Zeiss in 1953.
Since the last vertex is located only 18.8 mm away from the film plane, no viewfinder-mirror can be placed 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 so outstanding, that this lens is worth a precision 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.
