e-mount

The E-mount is a lens mount designed by Sony for their NEX ("New E-mount eXperience") and ILCE series of camcorders and mirrorless cameras. The E-mount supplements Sony's A-mount, allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:

Minimizing mechanical complexity, removing mechanical aperture and focus drive.
Shortening the flange focal distance to 18 mm compared with earlier offerings from Sony which used 44.5 mm.
Reducing the radius of the flange.The short flange focal distance prohibits the use of an optical viewfinder as a mirror box mechanism cannot be included in this reduced distance. Therefore all E-mount cameras use an electronic viewfinder.
