Summilux-M 90 f/1.5 ASPH.
Creative Control Down to the Last Detail
The Summilux-M 90 f/1.5 ASPH. is a lens for images in which proximity is not created by distance, but by intention. The long focal length in combination with the exceptional lens speed provides every shot with intense presence. Its shallow depth of field enables precise separation of the subject and creates portraits that are full of emotion with smooth transitions and natural bokeh. At the same time, the optical precision of this lightweight telephoto focal length ensures perfectly sharp subjects in any light, even when the aperture is fully open.

Perfection Through Precision
The unique performance of the Summilux-M 90 f/1.5 ASPH. is not only guaranteed by the use of special materials and lenses, but also by the particularly precise and sophisticated manufacturing process. In addition to optical performance, this also guarantees the durability and lasting value of this unique lens. The extremely smooth focusing is one result of this incredible craftsmanship. The wonderful, controlled bokeh, which requires extremely precise adjustment of the lenses, is another.
Design of the Summilux-M 90 f/1.5 ASPH.
The optical design of the Summilux-M 90 f/1.5 ASPH. comprises eight lenses in six assemblies, including two aspherical elements for effective correction of aberrations and several lenses with anomalous partial dispersion for precise colour and contrast rendering. Despite its high speed, the lens delivers impressive sharpness even with a wide aperture and is characterised by creating a particularly soft, atmospheric bokeh. With a close focus distance of 1 metre and its precisely manufactured mechanics, the Summilux-M 90 f/1.5 ASPH. is not only suitable for classic portraits, but also for expressive scenes captured in minimal light.
