Canon RF 100mm f/2.8 L Macro IS USM Lens Review

The Canon RF 100mm f/2.8 L Macro IS USM is a premium macro lens built for Canon's full-frame RF system, combining 1.4x magnification (the highest of any RF-mount lens) with a versatile 100mm focal length that works equally well for portraiture and detailed close-up work. Its unique spherical aberration control ring lets you dial in soft-focus effects on demand, a creative tool that distinguishes it from conventional macro primes. The lens features Canon's hybrid image stabilization, Super Spectra coatings, and weather sealing, along with a nine-blade aperture for smooth bokeh.

Build quality and optics are in line with Canon's L-series standards, and the autofocus is fast and near-silent thanks to the USM motor. At 1.6 pounds and just under six inches long, it balances well on RF bodies without being overly heavy. The minimum focusing distance of 10.2 inches gives you ample working room for skittish insects or shallow depth-of-field portraits. For Canon shooters invested in the RF ecosystem who need serious macro capability and want the flexibility of a bokeh control ring, this lens delivers on both technical performance and creative control.
