Leica APO-Summicron-M 50mm f/2 ASPH. Lens (Black)

BH #LE5020 • MFR #11141
Leica APO-Summicron-M 50mm f/2 ASPH. Lens (Black)
Key Features
  • Leica M-Mount Lens
  • Aperture Range: f/2 to f/16
  • Apochromatic Design
  • One Aspherical Element
Pairing the classic normal focal length with an optically refined design, the black APO-Summicron-M 50mm f/2 ASPH. Lens from Leica is a fast standard prime characterized by its apochromatic designation. Using anomalous partial dispersion and high refractive index glasses in its design, this lens is capable of focusing red, green, and blue wavelengths at the same plane in order to virtually eliminate chromatic aberrations. One aspherical element is also featured in the design, to reduce spherical aberrations, and a floating element maintains clarity and sharpness throughout the focusing range from 2.3' to infinity. This compact 50mm lens is also distinguished by its compact form factor, making it ideal for use as an everyday lens. Like all M-mount lenses, this 50mm f/2 features a manual focus design, and a convenient focusing tab for more refined control during use.

Leica APO-Summicron-M 50mm f/2 ASPH. Overview

Pairing the classic normal focal length with an optically refined design, the black APO-Summicron-M 50mm f/2 ASPH. Lens from Leica is a fast standard prime characterized by its apochromatic designation. Using anomalous partial dispersion and high refractive index glasses in its design, this lens is capable of focusing red, green, and blue wavelengths at the same plane in order to virtually eliminate chromatic aberrations. One aspherical element is also featured in the design, to reduce spherical aberrations, and a floating element maintains clarity and sharpness throughout the focusing range from 2.3' to infinity. This compact 50mm lens is also distinguished by its compact form factor, making it ideal for use as an everyday lens. Like all M-mount lenses, this 50mm f/2 features a manual focus design, and a convenient focusing tab for more refined control during use.

Apochromatic design employs three elements made from anomalous partial color dispersion glass, as well as two high refractive index elements, in order to suppress chromatic aberrations throughout the aperture range for increased color accuracy and clarity.
One aspherical element reduces spherical aberrations for improved sharpness from edge to edge.
A floating element is used to maintain clarity and sharpness throughout the focusing range, from 2.3' to infinity.
In addition to the apochromatic designation, this lens also pairs a Gaussian type optical construction in front of the aperture along with a design resembling the Summilux-M 50mm f/1.4 behind the aperture, in order to significantly reduce distortion while also increasing overall sharpness and consistent illumination.
Bright f/2 maximum aperture benefits working in difficult lighting conditions and also affords greater control over depth of field.
Compact overall design is ideal for use in everyday shooting situations.
Manual focus design provides a minimum focusing distance of 2.3' with a maximum magnification ratio of 1:11.3.
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 39mm screw-in filters.

If I shoot monochrome, do I need the extra color correction for chromatic aberrations?
Asked by: Stephen
Not necessarily. You wouldn't notice the aberrations or fringing if you're mainly shooting Monochrome.

question

When can one expect this lens to arrive in stock??
Asked by: Anonymous
With Leica it is very difficult to predict when they will stock this lens. On a back-ordered Leica lens such as this one it usually takes at least 6-8 weeks to come into stock.

question

Why is this lens more expensive than the Summilux F1.4?
Asked by: Vladimir
Because it is Leica - there is no logic. They set random price and see if you will buy it.

question

i can't tell if this lens has auto focus?
Asked by: Anonymous
If you have to ask the question, you should read more about the Leica M system. It's far more remarkable than you possibly can imagine. It's ... magic!
