World's First* Medium Telephoto Macro Lens with a Maximum Magnification of 1.4x.

The RF100mm F2.8 L MACRO IS USM Lens is the world’s first* medium telephoto AF Macro lens with a maximum magnification ratio of 1.4x.  At its minimum focusing distance of 0.86 ft. / 0.26m, the RF100mm F2.8 L MACRO IS USM is capable of capturing detailed images while being remarkably versatile in operation. Whether capturing details of food, jewelry, or traditional macro shots, the RF100mm F2.8 L MACRO IS USM is a highly effective lens for macro photography.

High Image Quality and Bright, Fixed f/2.8 Aperture Telephoto Macro RF Lens

The RF100mm F2.8 L MACRO IS USM lens distinguishes itself by maintaining incredibly high image quality, edge-to-edge, even wide open at its f/2.8 maximum aperture. With 17 elements in 13 groups and a 9-blade aperture system, it can deliver detailed images with gorgeous background blur and versatility in low light.

5.83 in. Length, Approx. 1.6 lbs. Weight

Weighing approx. 1.6 lbs. and measuring 5.83 inches in length, the RF100mm F2.8 L MACRO IS USM lens designed for comfortable use on any EOS R series camera. With its 100mm fixed focal length, the RF100mm F2.8 L MACRO IS USM lens provides a great representation to capture impressive portraits, food photos, flowers and more with minimal distortion.

Optical Image Stabilizer with up to 5 Stops of Shake Correction**.

Because RF lenses are designed specifically for the RF mount found on EOS R series cameras, the lens and camera combine to share shooting data, helping to dramatically reduce the effect of camera shake that can occur when using handheld. This applies when capturing both stills and video, with up to 5 stops of stabilization** for accurate and clear imagery.

Hybrid IS Compensates for Angular and Shift Camera Shake during Macro Shooting

Equipped with the Hybrid IS technology, the Image Stabilizer of the RF100mm F2.8 L MACRO IS USM effectively reduces blurring in handheld macro photography by compensating for both angle and shift camera shake. This helps to deliver impressively clear, up-close results.

Spherical Aberration (SA) Control Ring Allows Adjustments to Shape and Character of Foreground/Background Bokeh.

The RF100mm F2.8 L MACRO IS USM features Canon’s first adjustable Spherical Aberration (SA) control ring on the lens barrel that allows you to adjust the depiction of the image’s background bokeh. Used to add a unique emphasis to your imagery, the SA Control Ring allows the user to change the shape and character of the foreground and background bokeh. A minus setting creates a dreamy, soft-focused look, while a Plus setting creates a bubble-bokeh-type look. Adding a third ring to the lens, the SA Control Ring has a notable surface that can be differentiated from the Control Ring and Focusing Ring. A lock mechanism can be found on the side of the lens which locks the SA control ring to the middle position rendering standard, traditional operation, with no SA optical effects.

Note: The effect of the SA control ring also changes depending on the aperture value*.
* The effect is greatest at maximum aperture, and the effect decreases as the aperture is stopped down. (To obtain the desired effect, shooting with Aperture Priority AE is recommended). The effect of the SA control ring depends on the subject conditions (subject and background, foreground distance, etc.).
 

Up to 8 stops of Shake Correction*** with Coordinated Optical Image Stabilizer and In-Body Image Stabilizer.

When combined with an EOS R series camera equipped with In-Body Image Stabilizer, the lens' Optical Image Stabilizer teams up with the In-Body Image Stabilizer to provide coordinated IS up to 8 stops***, further helping to alleviate shaking for photos and video, and adjusting the ratio from optical to in-body stabilization automatically throughout the zoom range so you have the best of both worlds.

High Speed, Smooth and Quiet Auto Focus with Dual Nano USM.

The RF100mm F2.8 L MACRO IS USM is equipped with dual independent Nano USMs to help achieve high-speed and focus accuracy throughout its focusing range. This helps you quickly focus and keep up with fast-moving subjects as well as provides smooth and virtually silent autofocus while shooting movies, so there is relatively no disturbance for you, the subject or in what you see visually and hear audibly during shooting and playback.

Control Ring for Direct Setting Changes.

The RF100mm F2.8 L MACRO IS USM lens has a separate, independent Control Ring that is located towards the front of the lens, which can be programmable for immediate exposure adjustments during still and video shooting. With the Control Ring, you can directly adjust settings such as shutter speed, lens aperture, exposure compensation and more. For photographers and moviemakers who would prefer a silent control ring, the clicking mechanism can be removed by a Canon service provider for a fee.

Dust - and Weather-resistant.

For reliable performance even when weather conditions get difficult, the RF100mm F2.8 L MACRO IS USM lens features dust- and weather-resistant construction in the lens mount, switch panel and all rings. Sealing is applied to lens joining sections, and switch panels to help prevent water and dust from entering into the lens.

Fluorine Coating

The RF100mm F2.8 L MACRO IS USM lens features fluorine coatings on the front and rearmost surfaces to help prevent dirt and dust from sticking to the lens, making it easy to clean smudges and fingerprints off.
