Sigma 694972 50-120mm F2.8 DC OS Contemporary Lens for Canon RF Mount
The Sigma 694972 50-120mm F2.8 DC OS Contemporary telephoto zoom lens for Canon RF Mount APS-C mirrorless cameras combines a constant F2.8 maximum aperture, HLA autofocus and OS2 optical stabilization. Stabilization is rated at 6.5 stops at 50mm and 4.5 stops at 120mm.1 Designed for portraits, events, indoor sports and filmmaking, its telephoto range brings background separation and perspective compression to a portable setup. Reduced focus breathing and a dedicated aperture ring add video-friendly focus behavior and direct exposure control.
Key Features
Constant F2.8 and Telephoto Background Separation
Use shallow depth of field to separate a portrait subject from the background, or use telephoto perspective compression to shape the look of product images. The maximum aperture stays available throughout the zoom range, so changing your composition does not mean giving up F2.8. An 11-blade rounded diaphragm complements the large-aperture design.
Portable 410g Canon RF Design
Keep a telephoto kit mobile as you move between portraits and outdoor-event scenes. The Canon RF configuration weighs 410g, combining a portable APS-C setup with the creative reach of a large-aperture telephoto zoom.
Specialized Glass and Individual Optical Testing
An 18-element, 13-group optical formula uses one FLD element, three SLD elements and four aspherical elements to help control aberrations and maintain contrast from the image center to its edges. Sigma also checks each lens through its own MTF measurement process.
Reduced Focus Breathing for Video
Focus changes during a take should not distract from the subject. Reduced focus breathing limits the accompanying change in framing, helping preserve the composition as focus shifts. This makes restrained breathing a practical tool for filmmakers, not just a specification.
HLA Autofocus and OS2 for Handheld Work
A direct, gear-free HLA linear motor delivers fast, precise autofocus with quiet operation. Fast focusing and OS2 optical stabilization work together to support demanding handheld photography, including portraits, events and indoor sports.
Aperture Ring and Simplified Controls
Adjust exposure directly at the lens with the dedicated aperture ring, whether you are making still images or recording video. Separate focus-mode and OS switches are omitted, keeping the interface simple while retaining hands-on aperture adjustment.
Dust- and Splash-Resistant Design
Sealing at the mount, manual-focus ring, zoom ring and cover connection helps resist dust and splashes during outdoor shooting.2 A water- and oil-repellent front coating makes the exposed surface easier to clean after use.

Footnotes:
1 Stabilization ratings are based on CIPA guidelines, measured at 50mm and 120mm using an APS-C mirrorless camera.
2 Dust- and splash-resistant construction does not make the lens waterproof. Avoid substantial splashing; water entry can cause major failure. Water-damaged internal mechanisms, optics or electronics may not be practical to repair.
