Features:
- SteadyShot INSIDE™ In-Camera Image Stabilization
A major reason for its compact, lightweight lens design is the benefit of
SteadyShot INSIDE™ in-camera image stabilization, built into every®
a (alpha) DSLR camera -- and enabling lenses to eliminate the extra weight
and expense of in-lens stabilization mechanisms
- DT Lens Design
A more compact, lightweight lens designed specifically for the APS-size CCD
imager used in some Sony® a (alpha) DSLR cameras
- Smooth Autofocus Motor (SAM)
The built-in Smooth Autofocus Motor (SAM) eliminates the need to use a mechanical
coupling system in the camera body to transfer auto foucs (AF) drive power
and control signals to the lens. Instead, AF control signals from the camera
body are sent to the lens-mounted SAM unit, which drives the focusing lens
group directly, helping to assure smooth AF response
- ED (Extra-low Dispersion) Glass
To reduce chromatic aberration at telephoto extension, correcting certain
wavelengths of light for sharp, clear images with well defined colors
- Circular Aperture
Because aperture blades form a near circle at the wide openings used for low-light
shots, spot-light sources have a pleasing circular defocused effect
