Carl Zeiss Biogon T* 21mm f2.8
Designed by Dr. Ludwig Bertele, the Biogon lens formulation exerts a powerful hold on the hearts of photographic fans around the world. Especially for use with the CONTAX G series, the T* 21mm f2.8 was perfected by Carl Zeiss using the latest in optical technology. Although the Biogon T* 21mm has an ultra-wide angle of view of 90 degreess, distortion is very low. High contrast is achieved even with the f stop wide open.
The Biogon T* 21mm lens combines rich gradation, clear, three-dimensional reproduction along with high colour saturation. This lens responds well to a wide variety of photographic applications from astistic expression to architectural photography.
The Biogon T* 21mm f2.8 lens uses a supplied optical viewfinder with a cross-hair reticle to provide an accurate ultra-wide angle view.
