At a Glance
Lightweight constant-f/2.8 performance for the EOS R system. The RF 28-70mm F2.8 IS STM pairs a practical standard zoom range with optical stabilisation, a 9-blade aperture, 0.24× magnification and a compact approximately 495g body.
A standard zoom designed around portability and performance
The RF 28-70mm F2.8 IS STM is built for photographers and creators who want the flexibility of a zoom while retaining the benefits of a bright constant aperture. Its 28mm starting point works well for everyday scenes, while 70mm reaches into portrait and detail territory.
Up to 7.5 Stops of IS
The lens provides up to 5.5 stops of optical stabilisation, with up to 7.5 stops possible with compatible cameras under Canon’s specified conditions.
Fast & Quiet STM AF
Lead-screw type STM delivers fast, precise and quiet autofocus suitable for both still photography and video.
0.24× Magnification
At 70mm, maximum magnification reaches 0.24×, giving the lens useful close-up flexibility for products, food and details.
Compact 495g Design
At approximately 495g and 92.2mm long when retracted, it is designed to stay comfortable during extended shooting.
Dust & Drip Resistance
Canon specifies anti-dust and moisture resistance, while noting that switches, buttons and the adjustment ring are not fully sealed.
Constant F2.8 for low light and beautiful bokeh
A bright f/2.8 aperture remains available from 28mm through 70mm. This gives you consistent exposure control when zooming and makes it easier to separate subjects from their backgrounds.
9-Blade Circular Aperture
The distinctive 9-blade diaphragm contributes to smooth out-of-focus rendering and attractive highlights, particularly when shooting portraits and lifestyle scenes at longer focal lengths.
Low-Light Flexibility
The wide aperture can support faster shutter speeds or lower ISO settings when available light drops, while the optical stabiliser helps reduce camera-shake blur.
Why F2.8 Matters
For anyone searching for a lightweight constant f/2.8 Canon lens, the RF 28-70mm offers a useful balance between speed, zoom flexibility and portability.
Up to 7.5 stops of image stabilisation with compatible cameras
The built-in Optical Image Stabilizer provides up to 5.5 stops of shutter-speed compensation from the lens. With compatible cameras, Canon states that the combined stabilisation capability can reach up to 7.5 stops.
Travel & StreetHandheld shooting becomes easier when working in changing light without constantly reaching for a tripod.
Evening ScenesOptical stabilisation can help when slower shutter speeds are needed and the subject itself is relatively still.
VideoOptical IS complements the quiet STM focusing system for practical handheld video setups.
*Actual stabilisation performance depends on camera compatibility, focal length and shooting conditions.
Lead-screw type STM for fast, precise and quiet focusing
The RF 28-70mm F2.8 IS STM uses a Lead-screw type STM drive system. Canon describes its magnetic sensor and feedback control as supporting fast and precise autofocus with smooth, quiet operation.
Photography
Quick autofocus makes the lens practical for people, travel, everyday moments and changing subjects.
Videography
Quiet autofocus helps reduce distracting focus-drive noise when recording video, making it a useful Canon STM autofocus video lens.
Get closer with 0.24× maximum magnification
The lens can focus as close as 0.27m at 28mm with AF, while Canon’s specifications list 0.24m at 28mm with MF. At 70mm, maximum magnification reaches 0.24×.
Product & Detail Photography
Move closer to small products, accessories and details without changing lenses.
Food & Lifestyle
Use the 70mm end and f/2.8 aperture for tighter compositions with background separation.
Two UD elements for controlled chromatic aberration
The optical design uses 2 UD lenses. Canon states that the configuration efficiently corrects chromatic aberration while helping minimise centre-of-gravity shifts as the focal length changes.
Sharpness from Centre to Edge
Canon’s product material describes image quality that extends from the centre to the edges, including performance at the widest aperture.
Balanced Handling
The optical arrangement is designed to keep the lens’s balance manageable while changing focal length.
Approx. 495g, 92.2mm retracted and ready for everyday carry
Canon describes the RF 28-70mm F2.8 IS STM as roughly the size of a can of soda in the hand. Its compact dimensions and approximately 495g weight make it an appealing option for photographers who value portability without giving up constant f/2.8.
67mm Filter Thread
The 67mm filter diameter supports a wide range of common circular filters for creative and practical shooting.
Dust & Moisture Resistance
Canon lists anti-dust and moisture resistance similar in concept to L-series durability, while clearly noting that controls are not fully sealed.
Important
Canon specifically notes that the switches, buttons and adjustment ring are not fully dust- and drip-resistant. Treat the resistance as protection for suitable conditions rather than complete weather sealing.
A flexible lens for travel, portraits, lifestyle, events and video
Travel Photographers28mm covers wider scenes while 70mm gives a tighter perspective without changing lenses.
Portrait & Lifestyle50–70mm at f/2.8 provides useful subject separation and a flattering working distance.
