The RF 100mm F2.8L MACRO IS USM is the world’s first AF macro lens with an incredible 1.4x close-up magnification, delivering stunning images. A Spherical Aberration Control ring lets you vary the Bokeh with a soft-focus effect, making this an exquisite portrait lens too.
Spherical Aberration Control Ring
The RF 100mm F2.8L MACRO IS USM features a Spherical Aberration (SA) Control mechanism to specify the look of out of focus bokeh areas, both in front and behind the subject and produces a soft-focus effect on the subject itself. An additional control ring on the lens is used to govern an electronic cam that actuates the focusing and floating lens groups independently by using two Nano USMs to change their location from infinity to close-up and change spherical aberration. This alters the bokeh for the desired effect.
Hybrid Image Stabilizer
The RF 100mm F2.8L MACRO IS USM has an optical Hybrid Image Stabilizer offering up to 5-stops compensation (CIPA standard) or up to 8-stops with coordinated Image Stabilisation with a camera that has an In-Body Image Stabilisation (IBIS) system (CIPA standard and tested with the EOS R5). Due to the high magnifications found in macro photography vibrations are greatly exaggerated. Canon’s Hybrid IS tackles this by providing up to 2-stops of IS at 1x magnification (under Canon’s test conditions). The combination of this and high-speed RF communication means that this lens surpasses the best technology in the EF range. With compatible Canon cameras that feature in-body stabilisation, higher levels of compensation are possible.
Dual Nano USM focusing motor
Using two Nano USM AF motors helps drive the lightweight optical elements with speed, precision and control, in near silence – ideal for video and stills. For high speed focusing, a more compact lens design and closer focusing, a floating lens group system was used which required two focus motors. One Nano USM is used for the conventional focusing group and the other for the floating focus group allowing them to be driven independently for the SA control as well as focus breathing suppression.
