    135mm · f/1.8

    Overview

    The Carl Zeiss Sonnar T* 135mm f/1.8 ZA is a high-end A-mount lens praised for exceptional sharpness and smooth bokeh. Optical weaknesses include noticeable spherochromatism and some distortion/chromatic aberration, though minimal. Build is solid metal but lacks weather sealing. Autofocus is screw-driven, audible, and slower than modern SSM lenses. The focusing ring has slight play. It suits portrait photographers prioritizing image quality over speed or weather resistance.
