LEICA SUMMARIT-M 90 mm f/2.5

LEICA SUMMARIT-M 90 mm f/2.5 lens is a perfect demonstration of how Leica's Summarit-M class is setting new standards in spherical lens design. A Leica M camera with a LEICA SUMMARIT-M 90 mm f/2.5 fitted is an extremely compact and handy unit. Compared to other 90 mm focal length lenses, there is hardly any intrusion into the viewfinder image.

The LEICA SUMMARIT-M 90 mm f/2.5 is a versatile telephoto lens that rounds off the new lens speed class of Summarit-M lenses.Despite being much more handy and lighter than the comparable 90 mm Summicron lens, it offers outstanding optical and
mechanical quality. Even at full aperture, this lens demonstrates excellent imaging capability with outstanding contrast over the
entire image field. A slight reduction in quality can only be seen in the corners - which are not even captured by the slightly smaller
format of the digital LEICA M8 - but even this can be improved significantly by stopping down to f/5.6.
