The Apo-Sironar-Digital is the ideal starter lens for the world of digital photography in the studio.  Optimised for digital photography, the Apo-Sironar-Digital provides exceptional imaging performance.

With an image circle of 140 mm, the Apo-Sironar-Digital always allows sufficiant movements for the current digital camera backs.  These are much smaller than the classical film sizes in professional photography.  As a result, the lenses for digital photography must also provide a much finer resolution which, in turn can only be achieved with larger working diaphragms.  The Apo-Sironar-Digital is therefore designed for use from a working stop of 8.

The lens features include apochromatic correction, freedom from distortion, high resoluton and uniform illumination.

The focal length of 90 mm allows favourable taking distances and angles especially in the studio: converging verticals can be corrected easily.

In addition, the Apo-Sironar-Digital can be used without restriction as a universal lens for film sizes up to 6 x 12 cm in conventional photography.
