Explore the world of portrait photography with this lightweight moderate telephoto lens. The wide f/1.8 maximum aperture helps your subject stand out by blurring cluttered backgrounds while the 75mm effective focal length (on APS-C camera) effectively frames your subject.
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 (alpha) DSLR camera -- and enabling lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms.
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.
DT Lens Design: A more compact, lightweight lens designed specifically for the APS-C size imager used in some Sony (alpha) DSLR cameras.
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.
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.
