17 November 2007
Conclusion: The Zeiss Sonnar T* 135mm f/1.8 ZA showed an outstanding performance within the APS-C test and it manages to keep most of these qualities on full format sensors as well. The resolution is very good at f/1.8 and great to downright phenomanal beyond.
Summary: A fast, high-performance telephoto prime lens with above-average close-up capabilities.One of the first Carl Zeiss lenses to go on sale for the Sony DSLRA100 camera, the 135mm F1.8 Sonnar T* is relatively large and heavy, with a massive front element.
