Zeiss Vario-Sonnar T* 24-70mm f/2.8 ZA SSM (Sony SAL-2470Z) - Review / Lab Test Report
25 January 2010
Conclusion: The Zeiss Vario-Sonnar T* 24-70mm f/2.8 ZA SSM produced outstanding performance figures in our APS-C test but it's not quite as good when used within its native full format scope. It is, of course, still able of delivering an outstanding center resolution but the corner quality disappoints at 24mm when using large to medium aperture settings.
Zeiss Vario-Sonnar T* 24-70mm f/2.8 ZA SSM (Sony SAL-2470Z) - APS-C Review / Test Report
31 October 2008
Conclusion: The Zeiss Vario-Sonnar T* 24-70mm f/2.8 ZA 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.
Summary: In terms of construction and optical qualities, such as resolution, chromatic aberration, and vignetting, this lens certainly makes worth its high price. This lens is among the finest lenses for cameras with an APS-C sensor. Distortion, especially at the ends of the zoom range, is not (yet?) corrected by the camera.
Pros: Optical top class quality (resolution, chromatic aberration and vignetting), Solid as a rock
Cons: Heavy: almost a kilo, Visible distortion at 24 mm, High purchase price
