Comments about Leica Leica 50mm f/1.4 SUMMILUX-M Aspherical -Black - Standard Manual Focus Lens for M System - USA:

The new Leica 50mm 1.4 m lens ASPH is one of the top performing 50mm lenses I have ever used. Sharpness is superb, contrast is excellent, and the bokeh (background blur) at 1.4 is smooth with an individual characteristic to it. I really like the fact that the built in pull out shade locks in place if you rotate the shade a quarter turn. Focusing can be accomplished either by rotating the focus ring, or using the finger tab which enables a more balanced hold of an M body since only one fingered is required to focus. This lens feels like a high quality product and the images that it is capable of producing is astonishing.
