Leica 50mm f/2.5 Summarit-M Manual Focus Lens (Black)

BH #LE5025MB • MFR #11-644
Leica 50mm f/2.5 Summarit-M Manual Focus Lens (Black)
Key Features
  • 6-Bit Coding
The Leica 50mm f/2.5 Summarit-M Lens is the standard lens in the Summarit-M class of rangefinder lenses. These Summarit-M lenses are designed to offer traditional Leica optical and mechanical excellence, while positioned at a price level below the current M ASPH lenses. With a maximum aperture of f/2.5, and by applying classical and proven spherical lens designs, these lenses provide excellent quality. These features also result in a very compact design.

This lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software based vignetting correction (for RAW images the lens used is simply recorded, no change is made).

Leica 11-644 Overview

The Leica 50mm f/2.5 Summarit-M Lens is the standard lens in the Summarit-M class of rangefinder lenses. These Summarit-M lenses are designed to offer traditional Leica optical and mechanical excellence, while positioned at a price level below the current M ASPH lenses.

This lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software based vignetting correction (for RAW images the lens used is simply recorded, no change is made).

All letter and number engravings will be made using the traditional "Leitz-Norm" font as originally used by Leitz Wetzlar during the 1960's, and the red button on the lens mount will be true to the original color used on lenses produced since the introduction of the M mount through the 1970's.
Includes "6-bit code" which allows the digital M8 camera to identify which lens is being used, and also to store this information in image metadata.
High quality, fast, compact and lightweight.
The 9-bladed circular aperture creates a shallow depth-of-field that brings attention to the subject and blurs the background, which is ideal for portraits and weddings.
Manufactured and marked "Made in Germany".
