The new Summilux-M 90 f/1.5 ASPH. enables portraits with a breathtakingly shallow depth of field - allowing for the subject to be emphasised in perfect focus whilst rendering the background in an appealing blur. The lens is distinguished by an elaborate construction comprised of 8 lens elements, two of which are aspherical in design and crafted out of specialised 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 optical design of the Summilux-M 90 f/1.5 ASPH. is at the cutting edge of lens technology, delivering outstanding levels of optical performance even at an fully open aperture; in addition, its short telephoto focal length not only facilitates perfect portraits, but also enables Available Light photography, while its minimum focus distance makes it possible to bring out intricate details for unique compositions. The combination of the extremely shallow depth of field (which facilitates the three-dimensional isolation of the subject from the background) and a focal length that still allows the photographer to maintain a certain distance, clearly sets the Summilux-M 90 f/1.5 ASPH. apart from classic portrait lenses. In addition to the use of specialised glasses and high-quality materials, the unique performance of the Summilux-M 90 f/1.5 ASPH. also benefits from an exceedingly high-precision lens construction. This not only guarantees outstanding optical performance, but also makes the lens an exceptionally durable and long-lasting tool. The standout rendition is a direct result of its meticulous craftsmanship - as is the stunningly beautiful bokeh in the out-of-focus areas. The combination of the extremely shallow depth of field, showcasing the three-dimensional isolation of the subject from the background, along with a longer telephoto focal length, clearly sets the Summilux-M 90 f/1.5 ASPH. apart from classic portrait lenses. With extremely shallow depth of field at its widest aperture, the Summilux-M 90 f/1.5 ASPH. enables meticulously controlled compositions based on high-precision focusing - which, on the Leica M, is further supported by the optional Visoflex viewfinder. The Summilux-M 90 f/1.5 ASPH. also represents an appealing addition to Leica's SL-System. Thanks to the M-Adapter L, the Summilux-M 90 f/1.5 ASPH. is also compatible with the Leica SL and SL2.
