50mm · f/1.2
The Zenitar-S 50mm f/1.2 is a characterful lens prioritizing swirly bokeh over sharpness. It is designed for APS-C but usable on full-frame with vignetting. Optical strengths include pleasing, painterly bokeh and attractive color rendering, though distortion contributes to the swirl. Weaknesses are soft corners and limited center sharpness, only acceptable beyond f/2.0. Build and handling are not detailed. It suits photographers seeking vintage bokeh effects rather than clinical sharpness.
