Sony SAL24F20Z - 24mm f/2.0 Wide Angle Lens for Sony Alpha DSLR's Essentials Kit

Product Details:

Superior Large-Aperture Performance - Like other large-aperture Carl Zeiss lens designs, this f2.0 lens is simply magnificent in its ability to capture brilliant high-resolution images in low-light conditions requiring fully open aperture.

SSM (Super Sonic wave Motor) - Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied.

Carl Zeiss T Coating - Coated optics were pioneered by Carl Zeiss and this superb lens features T (T-Star) coating that virtually eliminates the lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces.

Glass-Molded Aspherical Lens Elements - These precision lens elements correct distortion for sharper, more visually accurate images.

ED (Extra-low Dispersion) Glass - Because light of different wavelength (or color) bends at different angles when it passes through a lens, ED (Extra-low Dispersion) Glass is used in Carl Zeiss lenses to eliminate chromatic aberration by correcting certain wavelengths of light for sharp, clear images with well defined colors.
