This 90mm f2 APO-Summicron-M Asph lens is a portrait photographer's dream. It sits within Leica's well-renowned M-mount range and can be defined as a fast short telephoto lens with apochromatic designation. This means that the lens utilises a pair of anomalous partial dispersion glass elements to essentially eliminate colour fringing and chromatic aberrations. By doing so, you are left with a clear, precise image with enhanced clarity and colour accuracy. Spherical aberrations and damaging distortion are further minimised by Leica incorporating a single aspherical element and two high refractive index glass elements. Adhering to Leica's preferred manual focus design, you have the ability to work with subjects as close as 1m. This makes it an incredibly versatile portrait lens that guarantees to dive deep into facial detailings during close-up shooting, whilst retaining clarity and sharpness within multi-person portraits. This 90mm f2 is also great for photojournalism and theatre photog
