Leica 90mm f2.5 Summarit-M Lens: Leica At Ace Cameras

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.

The 90 mm telephoto 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.
