SAL1118 DT 11-18mm F4.5-5.6 Zoom Lens for DSLRA100 α™ (alpha) Digital SLR Camera
Developed specifically for APS-C format digital SLR cameras, the DT 11–18mm F4.5–5.6 (SAL1118) zoom offers an angle of view equivalent to that of a 35mm format, 16.5–27mm zoom lens. At 11mm it provides a spectacular 104º angle of view that goes beyond the limits of human vision, with significantly enhanced perspective that adds a sense of depth and drama to the scene. At 18mm it provides a more natural perspective that is perfect for snapshots and general photography. With zoom capability, it's easy to manipulate perspective to enhance the emotional impact of your photos.
Three aspherical elements and one ED (Extra-low Dispersion) glass element are incorporated to suppress aberration, and flaring and ghosting have been minimized to ensure excellent contrast and quality across the zoom range. This lens also has a circular aperture for beautiful defocusing, and an internal focusing mechanism for fast, responsive AF shooting.
