    Overview

    The Sony 135mm F1.8 ZA Carl Zeiss Sonnar T* is a high-end A-mount lens praised for exceptional sharpness and creamy bokeh. Optical weaknesses include noticeable spherochromatism even stopped down. Build is solid metal, but it is heavy (995g) and lacks weather sealing; the filter ring may loosen. Autofocus is screw-driven, audible, and slower than modern SSM lenses. It suits portrait photographers prioritizing image quality over speed, especially on SLT bodies or with an adapter.
