Canon RF 16mm F2.8 STM — Editorial Review
The Canon RF 16mm F2.8 STM is a tiny, inexpensive ultra-wide prime for the RF mount — roughly the size and price of a nifty-fifty, but covering a dramatic 16mm field of view. It's a lens that wins on portability and value while leaning heavily on in-camera corrections.

Ultra-wide in a pocketable, affordable package
Dustin Abbott and SLR Lounge both note the appeal: at just 165g it's ultralight, cheap, and delivers very good center sharpness — especially stopped down — making it useful for landscapes, vlogging, and even astro work. In DPReview TV's review — featured above — they frame it as a remarkable value with real optical caveats.
Honest cons
- Heavy distortion. The lens produces strong barrel distortion and relies on a mandatory in-camera correction that can't be turned off.
- Soft corners wide open. Corners are very soft at f/2.8 and need stopping down to improve.
- Chromatic aberration and vignetting. Both are heavy without the correction profile applied.
- Correction-dependent. Its rendering leans on software profiles rather than raw optical quality.
Where this lens fits
- Vloggers and content creators who want a wide, light, cheap lens that disappears in a bag.
- Travel and landscape shooters on a budget who shoot with corrections enabled.
- Beginners adding their first ultra-wide to an RF body without spending much.
- Not those needing edge-to-edge optical quality, correction-free files, or premium build.
