90mm F2 Apo M Black 6bit - 11884
In the Leica Telephoto 90mm F2 APO Summicron M Asherical Manual Focus lens, apochromatic colour correction and an aspherical lens surface were combined for the first time in this lens of this type. Of its five individual elements, two are made of high-refraction glass, while two others feature anomalous partial dispersion. Its brilliance and quality of resolution are exemplary even at full aperture. Light falloff is very low. Its fast aperture, for a 90mm lens, lets you shoot at relatively short exposure times even in dim light, helping to minimise the effects of camera shake, for instance when photographing street scenes from a distance. This lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software based vignetting correction (for RAW images the lens used is simply recorded, no change is made). Focal Length: 90mm Aperture: Maximum: F2, Minimum: F16 Camera Mount: Leica M Minimum Focus Distance: 0.9m Elements/Groups: 5/5 Filter Thread: 55mm Weight: 499g Dimensions: 78x64mm
