Fifty-nine grams is the sort of figure that sounds like marketing until you mount the lens and pick the camera up. The RF 28mm f/2.8 STM barely changes the balance of a full-frame R body, which is the difference between a camera that goes in the bag and one that stays in the drawer. Nothing about the barrel asks for attention.
Of the pancake lenses we recommend here, this is the one we hand to someone with a single camera and a habit of leaving it at home. Twenty-eight millimeters is wide enough for a street corner, a restaurant table or a whole room, and on an APS-C body like the R50 it becomes a 45mm that flatters faces. The leadscrew STM motor was built with video in mind, so focus moves smoothly and quietly rather than snapping.
Close focus is the detail that changes how you use it. Nine inches gets you to 0.17x, which covers food, flowers and the small things you would otherwise photograph with a phone, and Canon's in-camera corrections straighten the barrel distortion before you ever see the JPEG. Sharpness held up wide open at f/2.8 in our shots, and by f/4 there was nothing left to think about.
What you give up is sealing, and a little light. There is no weather resistance here, so a wet afternoon means a bag or a sleeve. And f/2.8 is only f/2.8, a stop and a bit behind the Micro Four Thirds pancake on this list, which matters if you shoot after dark more than you shoot in the rain.
Pros
- 59g, barely noticeable on a full-frame body
- Sharp wide open at f/2.8
- Quiet STM focus that suits video
- Focuses to 9 in. for close-ups
Cons
- No weather sealing
If you want one lens to live on a full-frame Canon, this is it: 59g, quietly sharp, and wide enough to make an ordinary walk worth photographing.
