Leica APO-Summicron-SL 28mm F2 ASPH Wide Angle Prime Lens for L Mount

With the APO-Summicron-SL 28mm F2 ASPH, Leica Camera AG is introducing another wide angle lens for the Leica SL system. The prime lens is the youngest member of the APO-Summicron-SL lenses, which stand for high light intensity and extremely fast autofocus.

After the 35, 50, 75, and 90 mm focal lengths, the APO-Summicron-SL 28mm F2 ASPH is the first true wide angle in this series that, thanks to exactly the same dimensions of each focal length, also has the same filter diameter feature. The angle of view of the lens predestines it for use in reports, indoors, and in architectural photography. It’s initial opening, which is large for this focal length and can be used without any loss of performance, enables additional design options through the targeted play with sharpness and blurring. Thanks to the L-Mount connection, the Leica lens is fully compatible with cameras from other partners of the L-Mount Alliance, which also have the lens connection developed by Leica.

13 elements – three of them with aspherical surfaces on both sides – in 10 groups contribute to a high image quality even with the aperture fully open. Natural skin tones, soft transitions into the bokeh, a high level of detail contrast, and sharpness right into the edges of the distortion-free images should further distinguish the lens qualitatively. A special feature of the APO-Summicron-SL 28mm F2 ASPH is the high apochromatic correction with this focal length. For the correction of chromatic aberrations, most of the built-in lens elements have an abnormal partial dispersion and are made of high-quality special glasses.

Powerful and robust stepper motors with DSD (Dual Syncro Drive) are used in the Summicron SL lenses for particularly fast autofocus. With these, the entire focusing range can be covered in just 250 milliseconds. In addition to autofocus, Leica is also breaking new ground with manual focusing: Summicron SL lenses use a new type of manual focus ring design. A ring magnet with alternating north-south polarization is embedded in this. If the ring is turned, the magnetic field changes. A sensor evaluates the magnetic field and sends its measurement signals to the main processor. Depending on the angle of rotation and the speed of rotation, the focus position is approached accordingly – according to Leica, manual focusing is even faster and more precise.

Price and availability

The Leica APO-Summicron-SL 28mm F2 ASPH is now available to pre-order on the Bhphotovideo.com web store for $5,195.
