Sony E-mount

Sony NEX-C3

Sony NEX-5 E-mount

The E-mount is a lens mount designed by Sony for their NEX ("New E-mount eXperience") series of camcorders and mirrorless cameras.^[1]
Initially this mount is implemented in Sony Alpha NEX-3 and NEX-5 with APS-C sensor size.^[2] E-mount integration into Sony camcorder products is provided with the Sony Handycam NEX-VG10.^[3] On 24 August 2011 new products were announced, specifically the NEX-5N as a successor for the NEX-5, the NEX-7 as a prosumer product,^[4] as well as the NEX-VG20 as the successor to the NEX-VG10. The Sony E-mount is also implemented on 35 milimeter video camera of Sony FS-100.^[5] The successor to the NEX-3 named NEX-C3 was released a few weeks earlier. The NEX-C3 was replaced by the NEX-F3 in June 2012, which was succeeded by the NEX-3N in March 2013. The first third-party camera to use the E-mount is the Hasselblad Lunar, announced at photokina on 18 September 2012 and expected to be released in early 2013.^[6]

In September 2013, Sony announced the first model from new ILCE series, the ILCE-3000. In October 2013, the first models with full-frame sensor size were released as Sony α7 and Sony α7R.

Available adapters

The Sony LA-EA4 adapter

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.
Any A-mount lenses can be used via the Sony LA-EA1,^[25] LA-EA2, LA-EA3, or LA-EA4 mount adapters which provide electronic contacts and electro-mechanical diaphragm control. They allow the body to control the aperture of the lens and provide automatic exposure and Exif data support. The LA-EA1 and LA-EA3 only able to autofocus motor lenses (SSM and SAM), screw driven lenses can be used with manual focus only. ^[26] Older samples of the LA-EA1, NEX-3 and NEX-5 require a firmware update for this to work. The LA-EA2 and LA-EA4 adapters support fast phase-detection autofocus with all A-mount lenses (except for the few dedicated manual focus A-mount lenses), including screw-driven AF lenses. However, their translucent-mirror design requires an optical element in the light path and thus causes a light fall-off of about 30% for the autofocus to work. Also, it slightly decreases image quality. The LA-EA1 and LA-EA3 do not need optical elements in the light path and thus will not change image quality in any way. The LA-EA1 and LA-EA2 are designed to cover the APS-C format only, whereas the LA-EA3 and LA-EA4 are full-frame capable (when used on a full-frame camera).

Techart offers unique autofocusing adapter which has motor which moves adapter flange along optical axis. It has Leica M-mount on the lens side, but via stacking additional adapter almost any SLR lens can be mounted. ^[27]
