Notes: 15mm f/2.8 Distagon
The Zeiss ZM 15mm f/2.8 Distagon (about $4600) is a super-exotic ultra-wide-angle rectilinear lens for the Leica M9/M8/M or Zeiss Ikon. You’ll also need the viewfinder ZI 15mm.
Hand-built in Germany, the 15/2.8 Distagon utilizes exotic types of glass including barium dense flint with a high refractive index and fluor crown with anomalous partial dispersion, as well as an aspheric lens element (unusual for Zeiss designs). Zeiss went all out with this design, hence it is the most expensive lens in the ZM lineup, an extremely well corrected lens with a complex optical design.
