Some lenses offer possibilities that go far beyond the ordinary and give rise to truly exceptional results. This 90mm Summilux lens 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 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.
