This is an impressive lens considering size and performance. At full aperture overall contrast is high and very fine detail is crisply rendered with very good clarity. With these types of lenses we are in the stratosphere of optical performance and the cutting edge is redefined regularly. Quality differences between lenses of several manufacturers can be detected, but are mostly immaterial for general photographic practice. On this level of optical performance the skills of the photographer are decisive. Added advantage for this Leica lens is the mechanical stability and the precision of the mount. The lens can be used with both extenders (1.4x and 2x) giving the photographer the option to have three different focal lengths (280-400-560) with a slight drop in performance when using the extenders.
