Overview

The Canon RF 100mm F2.8 L Macro IS USM lens offers outstanding sharpness and 1.4x magnification, exceeding typical 1x macro. Its spherical aberration control ring allows adjustable bokeh. Build quality is sturdy and weather-sealed, but the lens is longer and heavier than predecessors. Autofocus is fast and quiet, with effective image stabilization. Weaknesses include high price and potential distortion (~0.3% pincushion). It suits macro, portrait, and product photographers seeking professional-grade performance.
