Sony 85mm f2.8 SAM A-Mount Lens

A new addition to the compact, lightweight, reasonably priced  “Easy Choice” prime lens lineup. Sharp from the widest aperture, high contrast from image center to periphery, and a circular aperture for smooth defocusing. Basic features and performance that are suitable for serious photography. Internal lens motor (SAM) for smooth autofocus operation. Compatible with all Alpha bodies and NEX bodies through adaptor.

Product Features

Circular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

Circular Aperture
Distance Encoder

Distance encoder

The distance encoder plays an integral part in ADI flash metering, which delivers high precision flash metering that is unaffected by the reflectance of subjects or backgrounds. The distance encoder is a lens component that directly detects the position of the focusing mechanism, and sends a signal to the CPU in order to measure distance to the subject. During flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.

SAM (Smooth Autofocus Motor)

Rather than using the focus drive motor in the camera body, SAM lenses feature an autofocus motor built into to the lens itself that directly drives the focusing element group. Since the built-in motor directly rotates the focus mechanism, operation is significantly smoother and quieter than conventional coupled autofocus drive systems.
