Canon's innovative RF macro with Spherical Aberration control for unique bokeh effects.
The Canon RF 100mm f/2.8L Macro IS USM launched in 2021 as one of Canon's most innovative lenses. Beyond providing 1.4x magnification that exceeds the standard 1:1 macro, it introduces a Spherical Aberration Control ring that lets photographers adjust bokeh character from smooth to bubbly, a first in any interchangeable lens.
Optical quality is outstanding with exceptional sharpness and beautiful rendering. The SA Control ring adjusts spherical aberration from overcorrected to undercorrected, dramatically changing the bokeh appearance. IS provides approximately 5 stops standalone or up to 8.5 with IBIS bodies. Nano USM autofocus is fast and accurate.
Canon RF mount only, 67mm filter thread. This is the only lens of its kind with user-adjustable spherical aberration. The EF 100mm f/2.8L Macro IS USM is the predecessor without SA Control. Competitors include the Sigma 105mm f/2.8 DG DN Macro Art.
Holds value well given its unique features. Check SA Control ring rotation, IS operation, and AF accuracy at close focus distances. The 1.4x magnification reveals details invisible at standard 1:1. A genuinely innovative lens that offers capabilities no other macro lens provides.
