This is an artistic lens therfore this review is very subjective. I love the way the Zeiss lenses draw and this one draws beautifully. I own the 85mm f/1.4 for my canon and I was looking for something similar for my Leica. This one hit the mark.

The Zeiss 50mm f/1.5 Sonnar ZM lens for LEICA is an unusually compact, high-speed lens. It is superb for people pictures.

There are few lenses that are more hated and more loved than the Zeiss Sonnar C 50mm. Some photographers love the lens for its smooth bokeh and great 3D images, some hate it for its soft edges when shot wide open, and for its focus shift issues. I have been in both those categories.
