Sony SAL24F20Z Specification Guide

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.
