Press Release

December 12, 2019 - Leica Camera has added a new telephoto lens to the portfolio of extremely fast prime lenses for the Leica M-System. The Summilux-M 90 mm f/1.5 ASPH. renders portraits with a breathtakingly shallow depth of field – allowing for the subject to stand out in perfect focus with amazing clarity while the background appears lusciously blurred. The optical design of the lens sets new standards while delivering exceptional performance with the aperture wide open. In addition to the moderate telephoto focal length for portraiture, the high speed of the lens makes it ideal for available light photography and its short minimum focusing distance makes it possible to get close enough to bring each and every fine detail to life.

The optical design of the Summilux-M 90 mm f/1.5 ASPH. is extremely complex and features eight elements, two of which are aspherical and made from specialized glass, arranged in six groups,. A floating lens element – an engineering feat when implemented in such compact lenses – ensures that the outstanding performance of the lens is maintained at all focusing distances. Vignetting and distortion, generally encountered with such fast lenses, play practically no role at all thanks to the advanced design of the lens. The integrated lens hood of the Summilux-M 90 mm f/1.5 ASPH. can be quickly and easily deployed and locked with a twist to provide further protection against stray light and reflections.

A closest focusing distance of one meter and a reproduction ratio of 1:8.8 make the Summilux-M 90 mm f/1.5 ASPH. an ideal lens for portrait photography. Its high speed for this focal length fully utilizes the potential of the Leica M-Bayonet mount. This new Summilux-M has a close relation to the Noctilux-M 75 mm f/1.25 ASPH. in terms of optical design and construction and offers a similar, extremely shallow, depth of field that is around half the depth of the legenedary Leica Noctilux-M 50 mm f/0.95 ASPH.

The Summilux-M 90 mm f/1.5 ASPH. has both high quality materials and glasses as well as exceptional precision in the manufacturing and assembly process. This guarantees endurance and value can be seen first-hand in the smooth focusing action of the lens and the control over bokeh, which demand precise alignment of the optical system. With its ability to isolate subjects with an extremely shallow depth of focus and a focal length that simultaneously enables shooting from a less intrusive distance, the Summilux-M 90 mm f/1.5 ASPH. stands out clearly among the classical focal lengths for portrait photography.

With the separately available M-Adapter L, the Summilux-M 90 mm f/1.5 ASPH. is also available for use with the Leica SL-System and on other L-Mount cameras. Thanks to 6-bit coding implemented by Leica, the lens is automatically recognized by Leica SL and SL2 cameras and delivers optimum image quality on their high-performance high resolution sensors.

The Summilux-M 90 mm f/1.5 ASPH. is on sale now at Leica Stores, Boutiques and Dealers for $12,995.00.

Optical Design

The Summilux-M 90 f/1.5 ASPH. is distinguished by an elaborate construction comprised of 8 lens elements, two of which are aspherical in design and made of specialized glass types, arranged in 6 groups. A floating lens element – an engineering feat when implemented in such compact lenses – ensures that the superior optical performance of the lens is maintained across the full focus range.

The MTF technical data charts show that even at maximum aperture the lens delivers exceedingly sharp contrast and fine details in subjects regardless if they are near or far, with virtually no drop-off in quality towards the edges of the image. The close-focus distance of one meter, kept to a minimum for such a fast lens, allows for a maximum magnification ratio of 1:8.8 – meaning photographers can get as close as needed for the ideal portrait.

With its 90mm focal length and incredibly bright aperture, the Summilux-M 90 f/1.5 ASPH. fully utilizes the potential of the Leica M bayonet mount. In terms of optical design and the aesthetic of its rendering, the latest Summilux-M is closely related to the Noctilux-M 75 f/1.25 ASPH. For example, both lenses deliver similar, razor-thin in-focus areas that are half as slim as the depth of field achievable with the legendary Noctilux-M 50 f/0.95 ASPH.

The intricate design and use of specialized glasses ensure that optical aberrations such as vignetting and distortion are kept to a minimum. The integrated lens hood can be extended and locked in an instant, providing optimal protection from stray light and reflections.
