    Overview

    The Canon RF 135mm f/1.8L IS USM delivers outstanding resolution across the frame, with very low chromatic aberrations and distortion, making it one of the sharpest lenses tested (OpticalLimits). However, bokeh can appear busy in some scenes, and RAW vignetting is high at f/1.8, though auto-correction helps. Build quality is excellent, typical of L-series lenses. It suits photographers needing extreme sharpness and fast aperture, but those prioritizing smooth bokeh may note the technical bokeh in focus transitions (OpticalLimits).
