The Leica Summilux-M 90mm f/1.5 ASPH. lens is a prime lens that boosts both speed and excellent optics and is ideal for portraiture and mid-length images. Its impressively fast and bright f/1.5 maximum aperture enables marked control over depth of field when employing selective focus shooting, and also benefits working handheld in dim conditions. The distinguished optics features a pair of large-diameter aspherical elements to achieve impressive sharpness and low dispersion. The optical design also employs a floating element system for maintaining a consistent high image quality throughout the focusing range from 1m to infinity. An 11-blade diaphragm produces a very pleasing and rounded bokeh quality while a built-in lens hood reduces lens flare and ghosting.
