The 85mm f/1.4 Carl Zeiss Planar T* Prime Lens from Sony is a fast and bright lens with a wide-open maximum aperture of f/1.4. In conjunction with the Super SteadyShot image stabilization system of Sony Alpha DSLR cameras, this lens will provide excellent results even when hand-holding the camera in available light.
This Sony Alpha lens that has been designed for full-frame DSLRs, but is compatible with cropped APS-C image sensors. As a result its 85mm focal length becomes the 35mm equivalent of a longer 127.5mm telephoto lens. It is constructed of 8 elements in 7 groups, which all help to deliver sharp, clear photos throughout the zoom range.
It has a minimum focusing distance of 2.8' and a front-end filter diameter of 72mm, as well as both a focus hold switch and auto clutch feature. These provide better control of focusing whether you use auto or manual focus modes.
Aperture Range: f/1.4-22
With a maximum aperture of f/1.4, and minimum aperture of f/22, the high build quality of this lens means you can capture faster shutter speeds and a shallower depth of field than lenses with a higher maximum aperture.
For Sony Alpha & Minolta DSLRs
Optimized for Sony Alpha cameras, this lens becomes the 35mm equivalent of a 127.5mm lens when attached to smaller cropped APS-C cameras.
Carl Zeiss T* (T-Star) Coating
This Carl Zeiss lens features T* (T-Star) coatings that reduce the lens flare, internal reflections and light scattering that can otherwise occur on the surface of the lens' glass elements.
9x Circular Aperture Blades
Circular aperture blades produce smooth, rounded bokeh background effects when capturing spot-light sources in your pictures. Because the aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
Focus Mode & Focus Hold Switches
This lens is made with a Focus Mode switch and Focus Hold button, which offer better focus control whenever you need it. Switch between auto or manual focusing for more speed or precision, then lock the focus to keep it right where you want it.
