High performance. Compact size. Ingenious Engineering.
Prime lenses offer their own special qualities: they are compact and fast, and deliver outstanding performance. Their speed enables a wide range of new options, for instance the creative use of depth of field to isolate subjects from the foreground and background.
Pictures captured with SL-Prime lenses then also reveal the unmistakable bokeh for which Leica lenses are renowned.
Another advantage of fast prime lenses is that they allow the use of faster shutter speeds, either to capture fast-moving action or to prevent shake effects in pictures when shooting handheld in low light.
APO-SUMMICRON-SL 1:2/28 ASPH.
A Modern Classic
The APO-Summicron-SL 28 f/2 ASPH. may have the focal length of a classic wide angle lens – but the scope of its performance is on an entirely different level. Thanks to its light sensitivity – which is enormous for a 28mm lens – and the extremely sharp rendition that characterises the APO-Summicron-SL series, the lens enables versatile compositions with sharpness and blur in reportage and architectural photography. The exact positioning of the focal plane is facilitated by the fast and precise autofocus.
35 f/2 ASPH.
35 mm is unquestionably the true standard focal length, and is rarely missing from a well-provided gadget bag. The family of lenses with this universal focal length now has a new member – the high-performance Summicron-SL.
Thanks to its combination of reference-class imaging performance, dust- and moisture-proof sealing, and state-of-the-art AF technology, this lens knows no limits.
50 f/1.4 ASPH.
More than light alone
The Summilux-SL 50 f/1.4 ASPH. is conceived to deliver maximum optical performance and sets new standards in terms of imaging performance. When it comes to picture quality, this lens easily fulfills even the highest expectations.
50 f/2 ASPH.
Anything but standard
The new 50 mm lens sets new standards in terms of compactness and performance. Based on innovative technologies, the APO-Summicron-SL 50 f/2 ASPH. leaves nothing to be desired. Brilliance, corner-to-corner micro-contrast, and balanced, harmonious bokeh make the lens a true Leica classic.
75 f/2 ASPH.
Street, portrait, or whatever catches your eye: Conceived as a universal lens for all situations, the APO-Summicron-SL 75 f/2 ASPH. opens up new horizons for photography in the transitional zone between standard and telephoto focal lengths.
90 f/2 ASPH.
Closer to the action
High speed and an unmistakably aesthetic rendition of out-of-focus areas make this telephoto lens the first choice for every portrait photographer.
The precision and almost silent action of its autofocus give photographers decisive extra moments to concentrate fully on the creative aspects of their work and the people in front of their camera.
APO Apochromatic and more
The prefix ‘APO’ in the name denotes Leica lenses with the best imaging performance. From telephotos to wide-angles, all Summicron-SL lenses in the SL-System portfolio bear these coveted three letters before their names. For a long time, this distinction was reserved exclusively for telephoto lenses, as only they could achieve the exceptional quality required.
It is now over 40 years since the first APO lens built by Leica made its appearance – the APO-TELYT-R 180 mm f/3.4, in 1975. In 2012, the APO-Summicron-M 50 mm f/2 ASPH. became the first standard lens to bear this prestigious prefix.
Thanks to technological progress, more complex construction and new manufacturing methods employed in the SL-System, the design engineers were able to perfectly maximise the optical performance.
To us at Leica, APO means more than just the correction of longitudinal chromatic aberration, for which the purely scientific definition of the term ‘apochromatic’ stands. Above and beyond this, all other chromatic and monochromatic aberrations must also be optimised to a similar degree. This performance is corroborated by the corresponding MTF curves, and practically reaches the physically possible diffraction limits. Our quality expectations and demands have grown accordingly throughout the many years since the launch of the first APO lens, with the result that today’s APO lenses are fit for whatever the future may bring and deliver persuasive performance in combination with highest-resolution image sensors.
Proofs of performance
SL-Prime Lenses in Action
When pressures of time or limited accessibility to subjects make it impossible to change your position or lens, you can always rely on the variable focal lengths offered by SL-Vario lenses.
Old values, new ways
The Leica adapters let you use more than 150 Leica lenses on the Leica SL: the high-performance Leica S- and M-Lenses, the classic R-Lenses, and the award-winning Leica Cine Lenses.
