Zeiss Distagon T* 24mm f/2 ZA SSM (SAL-24F20Z) - Full Format Review / Lab Test
10 January 2011
Conclusion: The Zeiss Distagon T* 24mm f/2 ZA SSM may not be as fast as its Canon and Nikon counterparts but it's capable of delivering a better image quality at comparable aperture settings. It avoids the glory but also the difficulties of an ultra-large f/1.4 aperture in favor of a much higher peak performance. There's still a bit of corner softness at f/2, but beyond it unleashes its full potential.
