Design Details

The optical design encompasses 13 lenses in 10 groups. Multiple aspherical elements minimise spherical aberration and ensure crisp edge sharpness. Nine of the lenses are made of high-quality specialised glass elements with anomalous partial dispersion. This ensures effective compensation for chromatic aberration throughout the entire system. A floating element ensures consistent focusing performance even at a close focus distance of 24 cm. Thanks to the precise autofocus, reliable focus tracking is possible even if the subject is moving. The robust metal housing of the APO-Summicron-SL 28 f/2 ASPH. is sealed against dust and moisture, allowing it to be used in challenging environments.
