Balancing a super-wide focal length with a compact form factor, the silver Biogon T* 21mm f/2.8 ZM from ZEISS is a versatile lens designed for M-mount rangefinder cameras. Its wide-angle design is complemented by a Biogon optical concept, which nearly eliminates distortion for well-corrected, accurate rendering. A T* anti-reflective coating has also been applied to individual elements to reduce lens flare and ghosting for greater color accuracy and contrast in strong lighting conditions. Additionally, the lens's manual focus design permits working with subjects as close as 1.6' away.

I have number of Japanese Zeiss lenses and a German made 15mm . The fit, finish and optical design is excellent on all of them. The only complaint is some of the lenses have excess grease oozing out of the rear portion of the lens. I have had to clean this up with a toothpick and lens tissue. The 21mm is one of my favorites of the Zeiss line. Beautiful IQ. The attached photo was taken with a 6mp Epson RD1.
