{{ :lens:90mmf2_8-apo-ultron-silber-web.png?400|}}
==== Summary ====
The APO-ULTRON 90 mm F2 VM was specially developed for the Leica M-Mount. Its impressive construction comprises 8 lens elements, 6 of which are made of glass with abnormal partial dispersion – a technical masterpiece that ensures first-class image quality. Despite its outstanding performance, the lens is extremely compact at just 63.3 mm in length. Thanks to its 12 aperture blades, the aperture remains almost circular, creating a wonderfully soft bokeh. The combination of a long focal length and a large aperture of F2 enables an impressive background blur, which sets the scene particularly effectively.
