| Carl Zeiss BiogonŽ lens goes digital |
| |
The Carl Zeiss BiogonŽ T* 4.5/38 lens, the most appreciated lens available for the Swiss Alpa camera, the only interchangeable version of this well-reputed lens, was taken to test recently by Swiss precision product companies Alpa and Sinar. Alpa adapted the new Sinarback 54, a 22 Megapixel digital back for professional medium format cameras. With the Sinarback 54 attached to an Alpa camera, several high performance lenses were compared for effective image quality, among them new digital high resolution lenses from other lensmakers, and the famous Carl Zeiss BiogonŽ T* 4.5/38 lens in its newest configuration, featuring the new formula using the eco-friendly glasses. The purpose of this test was to find the best lens to deliver very high detail content in the images with very low distortion for a photogrammetric application.
According to Thomas Weber-Capaul of Alpa, the BiogonŽ lens once again lived up to its reputation of being arguably ”the best wide-angle lens in the world”: it came out the best of them all. The BiogonŽ lens, based on an optical formula developed by Dr. Ludwig Bertele in the early 1950s, proved to be better corrected against color fringing than the most recent competing ”apo” and ”digi” lenses. At Carl Zeiss, we were pleased to hear about this positive real world evaluation and we are proud to share this information with the readers of CLN. It gives further support to our claim that investing in Carl Zeiss lenses is future-proof, when it comes to image quality and optical performance.
