DT 35mm F1.8 SAM Prime Lens
You can shoot anything from landscapes to portraits with this lens, without ever feeling that the large F1.8 maximum apeture is another advantage: bright enough to allow hand-held shooting in low light, and capable of producing smooth defocusing effects that can add depth and artistic elegance to your images. As a bonus, it is small and lightweight making it unobtrusive on the camera, in a bag, or even in a pocket!
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.
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.

Capture wide scenes with optimal detail using the SAL35F18 Wide Angle Lens
and your compatible ? DSLR camera. An ALC-SH111 solid-circular lens hood and front and rear lens caps are also included. FEATURES:
- Large F1.8 maximum aperture - In combination with the in-body image stabilization provided by ? series cameras, the bright F1.8 maximum aperture of this lens offers a significant advantage for hand-held shooting in low-light situations. The high resolution of this prime lens and the smooth defocusing achieved by its large F1.8 aperture can be utilized to create images that have impressive depth and three-dimensionality
- SAM (Smooth Autofocus Motor) - Autofocus signals received from the camera body control a motor built into the lens. The internal motor directly drives the focusing group for smooth autofocus operation.
- Uncompromised basic features - At 0.23 meters the minimum focusing the SAL35F18 makes it possible to move in for spectacular close-ups. The front filter mount does not rotate when the lens focuses, and this is a distinct advantage for polarizing filter use. A distance scale is also provided.
