    Overview

    The Kern-Macro-Switar 50 mm f/1.9 AR is a solidly built Swiss lens from 1968, praised for extreme sharpness even at corners and a flat-field macro design focusing to 28 cm. Its bokeh is smooth with a subtle glow, and multicoating improves flare and contrast. However, focus throw is very long, requiring nearly three rotations, making it slow for action. The unique Visifocus depth-of-field scale is a standout feature. It suits photographers who value optical quality and macro capability over fast handling.
