Lens Overview — Canon 100mm f/2.8 L Macro IS USM
Key Features — Canon 100mm f/2.8 L Macro IS USM
1.4x Magnification Ratio: Exceeds standard 1:1 macro reproduction, allowing subjects to be captured larger than life-size on the sensor for extreme close-up detail.
100mm Prime Focal Length: Fixed focal length provides a natural working distance from the subject, useful for both macro photography and portrait work.
f/2.8 Maximum Aperture: Wide maximum aperture gathers more light and enables precise depth-of-field control, particularly valuable when isolating small subjects.
Hybrid Image Stabilization: Combines optical stabilization in the lens with in-body stabilization for significantly reduced camera shake during handheld macro shooting.
Canon RF Mount: Native mount for Canon EOS R-series mirrorless cameras, enabling full communication with the camera body for autofocus, IS coordination, and exposure data.
Ring-Type USM Autofocus: Ultrasonic motor delivers fast, quiet autofocus suitable for both stills and video, with smooth transitions between focus distances.

Description — Canon 100mm f/2.8 L Macro IS USM
The Canon RF 100mm f/2.8 L Macro IS USM Lens is a prime lens built for the Canon RF mirrorless mount, designed to cover full-frame sensors. Its fixed 100mm focal length makes it well suited to macro and close-up work, as well as portrait photography where a consistent working distance is beneficial. The f/2.8 maximum aperture enables solid performance in varied lighting and gives photographers meaningful control over depth of field.
A key feature is the Hybrid (Lens + IBIS) image stabilization system, which pairs optical stabilization built into the lens with in-body stabilization from compatible camera bodies — a particularly practical combination when shooting macro subjects handheld. The lens supports both auto and manual focus, offering the adaptability needed across a range of subjects and techniques. A 67mm filter thread provides access to a wide ecosystem of screw-in filters.
At 730g, photographers should account for its weight when planning handheld or travel use.
