The Canon RF 100mm F2.8 L MACRO IS USM Lens is a high-performance, full-frame macro lens designed for the Canon RF mount, primarily aimed at delivering exceptional image quality for macro photography enthusiasts and professionals. It features a bright f/2.8 maximum aperture that facilitates excellent low-light performance and depth-of-field control, making it versatile for portraits and detailed close-up shots. The lens incorporates a 1.4x magnification ratio, allowing for incredibly detailed close-up images with a minimum focusing distance of 0.26 meters, which is ideal for capturing intricate details of small subjects.

The lens is equipped with advanced optical image stabilization, providing up to 5 stops of shake correction, and up to 8 stops when used with certain EOS R series cameras with In-Body Image Stabilization (IBIS). This feature ensures sharp, blur-free images even in challenging shooting conditions. The lens employs Canon's Dual Nano USM technology, offering fast, smooth, and quiet autofocus, which is particularly advantageous for both still photography and video recording.

Canon's proprietary Super Spectra Coating is applied to minimize ghosting and flare, enhancing contrast and color fidelity in various lighting situations. The construction includes 17 elements in 13 groups, featuring one UD (Ultra-Low Dispersion) element to reduce chromatic aberrations and distortions. As part of Canon's esteemed L-series, the lens is built with weather-sealed construction, ensuring durability and reliability in adverse environmental conditions. The lens also features a unique Spherical Aberration (SA) control ring, allowing photographers to adjust the bokeh style and create softer focus effects. Compact and lightweight for a lens of its capability, the Canon RF 100mm F2.8 L MACRO IS USM is a remarkable tool for macro and portrait photographers seeking superior optical performance and creative flexibility.
