Zeiss Sonnar T* 135mm f/1.8 ZA (Sony SAL-135F18Z) - Full Format Review / Test Report
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. The produced contrast is also cracking straight from f/1.8. The quality of the bokeh (out-of-focus blur) is next to perfect for a conventional lens.
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. It's also extremely well-built, as you'd expect from a high-quality prime lens with a longish focal length.
