Sony Corp will launch seven interchangeable lenses for its "NEX" series of mirrorless cameras until 2012.
This was announced by Masashi Imamura, president of the company's Personal Imaging & Sound Business Group, at photokina2010, which is taking place in Cologne, Germany. Currently, there are only three interchangeable lenses that are compatible with the "E-mount," a lens mount for the NEX.
When Sony asked the users of the NEX about the camera, an overwhelmingly majority of them said that they want more lenses, said Toru Katsumoto, Sony senior general manager, Imaging Division 3.
Sony will release a wide-angle single focus lens, single focus macro lens, single focus portrait lens and telephoto lens under the brand name of "Carl Zeiss" within 2011. And the company intends to launch a zoom lens, wide-angle zoom lens and single focus middle-range lens under the brand name of "G Lens" within 2012. At photokina2010, mock-ups of those lenses were exhibited along with a flash unit.
Imamura also announced that Sony started to consider disclosing the specifications of the E-mount to third-party manufacturers. Some manufacturers have already released mount adapters, and an increasing number of users are attaching the lenses of film cameras to the NEX cameras.
The specifications of the E-mount include mechanical elements such as shape and electronic elements that deal with signals. But the company has not yet decided to what extent it will disclose the specifications.
Sony will update the firmware of the NEX in mid-October 2010 and the firmware of the NEX-VG10 camcorder in mid-November 2010 to responds to the following user complaints, which were cited most frequently.
- When a lens for the A-mount is attached to the NEX by using the "LA-EA1" mount adapter, its autofocus function does not work.
- It is not possible to change ISO sensitivity, auto HDR (high dynamic range) or aperture value by pressing a single button.
- It is not possible for users to set an aperture value for shooting a movie.
