Leica Summilux-M 50mm f/1.4 ASPH. Overview

Designed as a reference lens for the M-mount system, the black Summilux-M 50mm f/1.4 ASPH. from Leica is a versatile normal-length prime characterized by its bright maximum aperture and sophisticated optical design. Comprising eight elements in five groups, the lens features one aspherical element to reduce spherical aberrations and both anomalous partial dispersion and high refractive index glasses are used to control color fringing and chromatic aberrations for improved clarity. Additionally, a floating elements system is used to maintain consistent image quality throughout the focusing range, down to 2.3'. Additionally, the lens features a built-in extendable lens hood and is threaded to accept 46mm screw-in filters.

Versatile normal-length prime lens is characterized by a bright, fast f/1.4 maximum aperture to control depth of field for selective focus techniques, as well as to benefit working in low-light conditions.
One aspherical element is incorporated within the optical design, along with anomalous partial dispersion and high refractive index glass elements, to control aberrations and distortions at all aperture and focus positions.
A rear floating element is employed to maintain consistent performance throughout the focusing range, even at the minimum focusing distance of 2.3'.
Built-in extendable lens hood shades and protects the front element to reduce lens flare and ghosting. Additionally, the front of the lens is threaded to accept 46mm screw-in filters.

When does this lens was launched?
Asked by: JZE
According to Ken Rockwell it was 2004. I have had one since 2011, I believe it might be the best portrait lens ever made by anyone due to its incredibly realistic drawing and equally incredible bokeh.

Is there a protective filter that will fit this lens and still allow you to use the lens hood?
Asked by: Robert
Yes. Any of Leica's 46mm filters work perfectly with it and do not impede with pulling out the lens hood. For the UVa II filter, that would be B&H # LEUVAIIE46B, Leica cat# 13033 in black.

question

what lens filter can I use?
Asked by: Allen M.
One drawback about this incredible lens is that you cannot mount the lens hood with a 43mm filter attached to the lens. I have suggested a solution to Leica, which they are considering, but in the meantime, you can do the following. From B&H, order a Heliopan 40.5-43mm step-up ring (#270). It is 4mm x 45mm. Lay it flat on a piece of medium grit sand paper so that you can sand it to the finished size of 3mm x 45mm, and it will fit perfectly inside the outer prongs lens hood. You can now screw any 43mm filter into the Heliopan step up ring. Screw the filter into the step-up ring mounted on the lens hood before you mount the lens hood on the lens itself so you do not damage the front element of the lens. This may sound complicated, but it's not. I will post some photographs on the Leica Forum website.

question

Can this lens be mounted on a Canon 5D Mark II?What will be the differences in colors from this lens and characteristics compared to a Canon?
Asked by: Jane s.
Unfortunately, no, we do not carry any lens mount adapters that would allow you to attach a Leica M-mount lens onto the Canon EF lens mount.
