Additional information:
Carl Zeiss Distagon 21 mm f/ 2.8 C/Y - a new design and is a gem wide-angle lens for Contax/Yahica mount.
It is a long lens for a wide angle - about four inches (an inch longer than the Zeiss 135).
It uses low dispersion glass and controls distortion well cause that was the thing Carl Zeiss engineers mostly worked with. This is the best Zeiss wide angle lens in my opinion.
Known analog: Leica Elmarit-R 19 mm f/2.8
