Sony 24 -70mm f/2.8 Carl Zeiss Reviews
Photoreview reviews the Sony 24 -70mm f/2.8 Carl Zeiss and writes;
“Vignetting (edge darkening) was negligible at all apertures and focal length settings. Rectilinear distortion was barely detectable. Bokeh (out-of-focus blur) was very smooth and attractive.”
SLRGear reviews the Sony 24 -70mm f/2.8 Carl Zeiss and writes;
“It’s test results for sharpness show it to be extremely sharp, competing very closely with the Canon and Nikon comparable lenses. It’s is optimized to provide its sharpest results in the wider portion of its aperture range, which makes sense to me, as this is a lens you will spend a lot of time shooting wide open.”
Photozone reviews the Sony 24 -70mm f/2.8 Carl Zeiss and writes;
“The Zeiss ZA Vario-Sonnar T* 24-70mm f/2.8 SSM will surely find many fans. In terms of resolution is may well be the hottest cake around in this class and neither distortions nor vignetting are problems to worry about (all within the APS-C scope). Lateral CAs may be visible at times in wide-angle images but it’s a non-issue in the middle to upper zoom range.”

Sony 24 -70mm f/2.8 Carl Zeiss Specifications
High-performance Carl Zeiss large-aperture zoom. The SAL-2470Z Carl Zeiss Vario-Sonnar f2.8 24-70mm Zoom Lens is a brilliant all-around performer—with SSM (Super Sonic wave Motor) design for fast, silent auto-focus, pro-quality Carl Zeiss T* coated optics to reduce lens flare, and 17-element design with two aspherical and two ED glass lens elements to minimize distortion and virtually eliminate chromatic aberration. It also benefits from the Super SteadyShot image stabilization built into every Sony system DSLR—and its wide-angle to medium telephoto range and compact, lightweight design is ideal for a wide range of shooting applications (35mm equivalent: 36-105mm).
Compact Design, All-Around Versatility
This superb 24-70mm zoom lens is an excellent choice for a wide range of photo applications — a lens you can put on and leave on, providing large-aperture brightness that’s easy to carry (35mm equivalent: 36-105mm).
Superior Large-Aperture Performance
Like other large-aperture Carl Zeiss lens designs, this f2.8 24-70mm zoom lens is simply magnificent in its ability to capture brilliant high-resolution images in low-light conditions requiring fully open aperture.
In-Camera Image Stabilization
A major reason for its compact, lightweight design is the benefit of Super SteadyShot in-camera image stabilization, built into every Sony ? system DSLR — and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms.
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.
The SAL-2470Z is designed with 17 lens elements in 13 groups, including 2 aspherical elements and 2 ED glass elements. Floating motion between the third and fourth groups of lens elements helps compensate for any aberrations caused by the zooming action of the lens.
Glass-Molded Aspherical Lens Elements
These precision lens elements correct distortion for sharper, more visually accurate images across the entire zoom range of the lens.
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.
