The RF28-70mm f/2.8 IS STM is the lens we leave on the camera when we do not know what the day will bring. The constant f/2.8 aperture is the headline: it keeps shutter speeds up indoors and gives portraits a soft background without a prime swap. The 28-70mm range covers group shots, food, and tighter portraits, and the lens is light enough to stay on the body.
What makes it a better default than the 24-70mm L for many people is the size. It is lighter and less front-heavy on an R-series body, so it comes along instead of staying in the bag. We paid attention to how it handled on a long walk: the zoom ring moves smoothly, the STM focus is quiet enough for video, and the optical stabilization helps at the long end. Canon builds in weather resistance it calls L-series equivalent, and we still wipe it down after a wet shoot.
The two UD and two aspheric elements do their job: images stay crisp across the range, and the f/2.8 aperture holds color and contrast together in low light. For a small room or a tight group shot, the 24-70mm L is the better tool; its wider start gets the whole scene in. For everyday people, travel, and events, this lens is wide enough. If you want one lens that covers most of what you shoot and does not cost L money, this is the one we recommend.
Pros
- Constant f/2.8 through the zoom range
- Lighter than the 24-70mm f/2.8 L
- Weather-resistant build
- Quiet STM focus for video
Cons
- Wide end stops at 28mm
We recommend the RF28-70mm f/2.8 as the default RF lens for most photographers because it pairs a fast constant aperture with a size and cost that make it easy to carry every day.
