Zeiss ZM 21mm F/2.8 Biogon For Leica

The Zeiss ZM 21mm f/2.8 Biogon for Leica is a very wide-angle lens with a reasonably fast aperture. Key features include:

• Great for architectural, landscape, and product photography

• 1.8-foot minimum focusing distance

• Ten-blade curved aperture

Its flare control and lack of geometric distortion provides useful accuracy for architectural, landscape, and product photography.

In this focal length I think the Zeiss is a superb value: as sharp as you could dream, very well made. The aperture ring adjusts very distinctly by feel and the focusing ring is quite smooth.

Honestly, for the price difference I’d go with the Zeiss.
