LEICA APO-SUMMICRON-R 90 mm f/2 ASPH

LEICA APO-SUMMICRON-R 90 mm f/2 ASPH
A fast, high-performance 90mm lens for portraiture and photojournalism. Also excellent for quick snapshots when you want to take pictures inconspicuously from a distance. Its high speed permits relatively fast shutter speeds that prevent blurred images caused by camera motion. With an aspherical lens element and Apochromatic correction, this lens sets the standard in the category of short telephoto lenses.

LEICA APO-SUMMICRON-R 90 mm f/2 ASPH

Apochromatic correction and the use of a lens element with an aspherical surface are combined in this compact telephoto lens for high-performance imaging. Two of the five lens elements are made of high-refraction optical glass. Two other lens elements have anomalous partial dispersion. As a result, brilliance and resolution are exemplary, even at full aperture. Peak performance is chieved at full aperture. Vignetting is already minimal with the lens wide open. As a result of the large aperture of f/2 and impressive contrast rendition, it produces a particularly bright viewfinder image that permits very accurate and positive focusing, even in poor light. The nearest focusing distance is 0.7 m (27.5 in), so that subjects as small as 14 x 21 cm (5.5 x 8.25 in) can be explored. Combining this lens with the LEICA APO-EXTENDER-R 2 x produces a high-performance tele combination of 180 mm f/4.

LEICA APO-SUMMICRON-R 90 mm f/2 ASPH user reviews

    "This is simply the finest 90mm lens in the world, regardless of speed, for 35mm photography. Color rendition is outstanding with excellent flare supression for the focal length. The resolving power of this lens is already at the limit of the finest resolving color transparency films at f/2. Unlike some reviews that state the lens is slightly soft at its closest focus distance, my observation is it is tack sharp at all distances. I shoot almost exclusively the highest resolution films, both black and white and color, and I am always astounded at the reproductive quality of this lens. It is in my opinion the best 90mm lens that has ever been produced"
