| Production of Sinaron Digital AF has started! |
| |
 |  | On Monday, 22nd of August 2005, series production of digital lenses for Sinar m started at Carl Zeiss, while a group of 50 journalists and Sinar dealers from North America visited the factory in Oberkochen, Germany. The Sinar m is the only digital medium format camera today which is designed from scratch solely for professional photography.

 | | Sinar avoids the usual compromises with which other medium format autofocus cameras try to appeal to amateur photographers and thus maximise production numbers.
The 4 new sinaron digital AF lenses feature fully electrical focus and iris control. Thus, autofocus is possible as well as remote controlled focusing for positioning the focus precisely where the photographer wants it, a fully professional feature not available in other medium format autofocus cameras which were designed with amateur horizons in mind.
The 4 sinaron digital AF lenses from Carl Zeiss are:
- the retrofocus wide angle lens Distagon T* 4/40,
- the standard lens Planar T* 2,8/80,
- the macro lens Makro-Planar T* 4/120, and
- the telephoto lens Sonnar T* 4/180.
The optical design of these lenses takes into account the aberrations caused by the filters in front of the digital imaging sensor. Since digital imaging sensors show better flatness than silver halide film in most medium format film magazines, the Carl Zeiss sinaron digital AF lenses also are designed and adjusted for superior flat field characteristics. This leads to a superior detail definition from center to corner, compared to other medium format lenses. |
