Fotodiox Lens Adapter with Leica 6-Bit M-Coding - Compatible with Leica R SLR Lenses to Leica M Mount Rangefinder Cameras

Mirrorless cameras aren't only revolutionary because of their compact size; they're even more versatile for mounting lenses than their full-sized counterparts! Whether you're shooting digitally or on film, Fotodiox offers the world's largest selection of lens adapters with strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Mix camera/lens platforms or reinvigorate vintage glass; our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality.

Putting old lenses onto new, high-performance DSLR or mirrorless cameras seems counter-intuitive so why would anyone want to? The simple answer is that many older lenses can capture images that have that elusive quality known as character. For photographers or videographers who want to create unique images that express their personal style, character can be even more important than resolution numbers, corner-to-corner sharpness, and other advantages of the near perfect lenses that are quite common today.

The imperfections and aberrations of older lenses are the very strengths that set them apart from modern lenses. Additionally, a fully mechanical lens is likely repairable longer and less expensively than modern focus-by-wire lenses. Old lenses also let you change camera systems, or your mount can get retired and your lenses won’t be bricked. At the extreme case, some mirrorless lenses require firmware updates for every new body, so even if the mount stays around lenses won't stay on that update list forever (for instance Nikon's new E lenses are incompatible with cameras just two generations old).

The Fotodiox standard adapter is the perfect purchase for anyone who’s new to using adapter systems or doesn’t switch their lenses often or are using off brand lenses that may not have been machined to the exacting specs of the mount they were designed for. An affordable alternative to our Pro adapter, these adapters can be adjusted to prevent light leaks and ensure the perfect fit.

The Leica M 6-bit lens coding system works together with firmware in the newer camera bodies (starting with M8) to correct for various lenses. The lens coding is called ‘6-bit coding‘ because six fields in the bayonet ring are marked in black or white to represent a number from 1 to 64 in binary code. The information on the lens is used to help the camera to optimize image quality and this information is also written into the EXIF image file.

More information along with a list of the coding sequences can be found on the Leica Camera Forum Wiki - Leica 6-Bit M-Coding Page.
