This means that the Summicron-SL lenses achieve values that are among the best in the full-frame system segment in terms of speed, precision, and operating noise. Thanks to these, the entire focusing range can be traveled completely in fractions of a second. In the Summicron-SL lenses, the drive units installed are extremely powerful and robust stepping motors with Dual Syncro Drive™. This requires a dynamic drive system without any room for error. In this procedure, the focusing lens elements must be moved rapidly in accordance with the speed specifications of the contrast AF system.

Several contrast measurements at various focusing positions must be made before the correct direction for focusing can be determined and followed by precise focusing. While being able to work within tight space constraints, the drive motors used must maintain peak performance in all situations to be chosen for such a cutting-edge camera system. This system, comprising two especially light focusing lenses, allows the construction of particularly small and compact drive systems.

Specialists from the areas of optical engineering, mechanical engineering and electronics worked together as an interdisciplinary team on the development of a unique lens concept based on double internal focusing.
