Adapts Leica M Mount Lenses to fit on Sony E Mount NEX 

• The E-mount is a lens mount designed by Sony for their NEX ("New E-mount eXperience") series of camcorders and mirrorless cameras.
• Due to the short flange focal distance of the Sony E-mount, many lenses can be adapted to be used on the Sony E-mount, although a crop factor will have to be taken into account for all cameras with APS-C or Super-35mm sensor format.
• These adapters do not allow for autofocus, however automatic exposure is possible in the aperature priority mode.

• The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M series up to the current film Leica M7 and digital Leica M.

• This lens mount has also been used by Minolta on the Minolta CLE rangefinder camera, by Konica on the Hexar RF, by Voigtländer (Cosina) on the late models of the Bessa range, by Rollei on the Rollei 35RF and very recently by Zeiss Ikon on the latest Zeiss Ikon rangefinder camera and by Ricoh in the GXR system.
