Canon Canon RF 16-28mm f/2.8 IS STM Lens Review
Canon's RF 16-28mm f/2.8 is a sharp, stabilized marvel for video shooters, but its autofocus and lack of sealing hold it back from being perfect.
Overview
Canon's RF 16-28mm f/2.8 IS STM is a weirdly specific lens that's absolutely brilliant at its one job. It's a compact, stabilized, constant-aperture wide-angle zoom for full-frame RF cameras, and if you're a hybrid shooter who needs that exact thing, it's fantastic. The one thing to know is that it's not a do-it-all travel lens, it's a specialized tool for video and creative pros who live at the wide end.
Performance
The optical performance is in the 92nd percentile, which is no joke for a lens this small. The image stabilization is also top-tier, hitting the 89th percentile, and that combo makes handheld video look incredibly smooth. What surprised me, though, is the autofocus. It's a leadscrew-type STM motor, and it lands in the 47th percentile. For stills, it's fine, but for fast-paced video autofocus, you might feel it hunting a bit compared to the latest linear motors.

Value & Pricing
Prices are bouncing between $930 and $1049. At the lower end, around $930, it's a compelling value for the optical and stabilization quality you get. At $1050, it starts to feel a bit steep for a lens with no weather sealing and middling autofocus. Shop around for that $930 price.
vs Competition
This isn't really competing with those 35mm and 55mm prime lenses in the list. Its real competition is the Canon RF 15-35mm f/2.8L IS USM. The L lens is weather-sealed, has better build and AF, but it's bigger, heavier, and a lot more expensive. This 16-28mm is the compact, cost-effective alternative. For Sony shooters, the similar tool is the Tamron 17-28mm f/2.8 Di III RXD, which is also a great compact option but lacks built-in stabilization.

Verdict
If you're a Canon RF shooter who does a lot of handheld video, real estate, or landscape work and you prioritize a light kit, this lens is a no-brainer. Just get it. If you need robust weather sealing or rely on snappy continuous autofocus for events, save up for the RF 15-35mm f/2.8L. This lens knows its audience, and for that audience, it's a winner.
