Sony SAL-24F20Z User manual

Superior Large-Aperture Performance
Like other large-aperture Carl Zeiss® lens designs, this f2.0 lens is simply magnicent 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 are, internal reection 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 dierent wavelength (or color) bends at dierent 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 dened
colors.
