Leica 50mm f1.4 Summilux-M Asph Lens: Lenses At Ace Cameras

A combination of the know-how of Leica's engineers and the latest developments in manufacturing technology has resulted in this outstanding standard lens. It delivers high-contrast images, with high-resolution detail, even at its widest aperture, and down to its minimum focusing distance. This is made possible by a number of factors including the use of a floating element, special glass types with unique refraction properties, and elements with aspherical surfaces. The properties of this lens not only make it ideal for any photo situation demanding a handy all-rounder with the natural image angle of the 50 mm standard focal length, but also for available light situations, selective-focus shots, and even fine art photography - usually the preserve of much larger formats. Its wide-ranging versatility also makes it a top choice in assembling a Leica M lens outfit.
