The Lens is Crisp Center to Edge

Sony 85mm f/2.8 SAM Lens Sony 85mm f/2.8 SAM Lens. The the very first lens designed for full-frame cameras for the ‘Easy Choice’ line, so its release is a major expansion of the line overall. 85mm is a quite normal portraiture length due to the the native perspective that it presents. Mounted onto an APS-C image sensor camera, 85mm f/2.8 functions as an equivalent 127.5mm telephoto lens. It contains a Sonnar-style optical layout that is considered just perfect for middle-range telephotos.

The lens is crisp center to edge, and brings out smooth defocusing due to its big f/2.8 aperture plus the circular aperture layout. At a minimum focusing distance of 0.6 meters it's the shortest distance in its class, while the SAM motor assures smooth AF functions.

With quality mechanical and optical attributes in the lens, it's made for serious photographers and should amply gratify intermediate through advanced users.

Color fringing, which exists on most easy choice lenses, can be seen under strong contrast situations. There are fine traces of purple and magenta plus purple fringing which is visible between the dark to light borders. Fringing disappears somewhat when the it's stopped down 2 or more stops, or when extensive lighting (such as a studio) is used to soften up contrast of a subject. Contrast and color also is inclined to be somewhat on the softer side, prompting you to shoot RAW at first if you're unfamiliar with the optical and behavior performance of the lens. Sep 2, 2011. Typical Internet price $259.
