Anew benchmark in portrait photography
Some Lens offer creative possibilities that go far beyond the usual and make shots unmistakable. The Summilux-M 1:1.5/90 ASPH. enables portraits with a breathtakingly shallow depth of field, with a subject in perfect focus on the one hand and a pleasant-looking background resolved in the blur on the other.
The optical design of the Summilux-M 1:1.5/90 ASPH. sets new standards: it achieves exorbitant optical performance even with the aperture fully open and, in combination with the light telephoto focal length, enables not only outstanding portraits, but also available light photography and, thanks to the close focusing distance, the highlighting of details with a unique design.
The optical design
The Summilux-M 1:1.5/90 ASPH. is very elaborately constructed with 8 lenses, including two aspherical lenses made of special glass, in 6 groups. A floating element, which can only be realized with great effort in such compact lenses, ensures that the extreme optical performance of the lens is maintained at all distance settings.
This extraordinary performance is also demonstrated by the MTF curves, which show the finest details and excellent detail contrast at all shooting distances with virtually no loss of performance right up to the edge, even when the aperture is fully open.
The shortest shooting distance of one meter, which is unusual for such a fast lens, enables a reproduction scale of 1:8.8 and underlines the excellent suitability of the lens for portraits. With its speed at this focal length, the Summilux-M 1:1.5/90 ASPH. fully exploits the possibilities of the M bayonet. Optically and in terms of design, it is closely related to the Noctilux-M 1:1.25/75 ASPH. and offers approximately the same extremely narrow depth of field as the Noctilux-M 1:0.95/50 ASPH.
The elaborate construction and special lenses ensure that the image errors of vignetting and distortion, which are virtually unavoidable with very fast lenses, play practically no role. The built-in lens hood can be pulled out and locked in place in no time at all, ensuring optimum protection against stray light and reflections.
Perfection through precision
The unique performance of the Summilux-M 1:1.5/90 ASPH. is not only ensured by special materials and glass, but also by the particularly precise and sophisticated manufacturing process. In addition to the optical performance, it also guarantees the durability and value of this special Lens. The extremely smooth focusing is one result of this craftsmanship, the wonderful and controlled bokeh, which requires extremely precise adjustment of the lenses, is another.
With its ability to vividly isolate subjects through an extremely small depth of field range and at the same time allow a certain distance through its focal length, the Summilux-M 1:1.5/90 ASPH. clearly stands out from the classic portrait focal lengths.
With its extremely shallow depth of field at fully open aperture, the Summilux-M 1:1.5/90 ASPH. not only enables precise image control, but also places high demands on precise focusing, for which the Visoflex viewfinder on the Leica M does a good job.
With the M-Adapter L, the Summilux-M 1:1.5/90 ASPH. is also an attractive addition to the system for the Leica SL and Leica SL2.
