Reviewer Consensus
Strong
The Canon RF 16mm f/2.8 STM is a remarkably compact and affordable ultra-wide prime that provides excellent center sharpness for street and travel photography. That said, it relies heavily on digital correction to manage extreme native distortion and vignetting, and it lacks weather sealing or a dedicated focus switch.

So I know how else to put it, this Canon RF 16mm f/2.8 is an affordable little gem. What can we really complain about? Could be sharper wide open, autofocus motors maybe a little bit noisy, but otherwise this is actually an awesome little travel walk around lens.
-
The Canon RF 16mm f2.8 is that rarest of things: an exotic lens at an accessible price.
- OpticalLimits 3/10
The Canon RF 16mm f/2.8 STM is a lens with many facets. It comes down to where you come from and what you want.
-
This makes the Canon RF 16mm f/2.8 a pretty specialized choice: great if you need the utmost in portability or low price, but substantially flawed if you need solid build quality or optical performance.
-
There are a number of very good reasons that specialist lenses often cost a lot of money, and when they don’t we need to tread carefully.
-
While the RF 16mm f/2.8 lens has extreme barrel distortion, strong lateral CA, and a budget AF system, the image quality this lens produces is consistently quite good. Factor in the ultra-low size, weight, and price, and this lens becomes a great deal.
-
The title to my video review is that the Canon RF 16mm F2.8 STM is fun, flawed, and useful.
-
All in all, considering that this is one of Canon's lowest budget lenses, its build quality is perfectly acceptable. It works fine, although video makers should slow down their autofocus where possible and be ready to tolerate some focus breathing.
-
Honestly, I didn’t paint a very pretty picture of this lens but I still really love it.
-
It is not perfect technically, but it is a perfectly usable and extremely versatile ultra-wide lens at a very keen price. It seems to be well made and many of the shortcomings optically may well not be significant drawbacks for the applications the lens is intended for.
-
[I]f you can buy into the amount of digital correction that Canon is automatically applying to in-camera JPEGs, or wants you to apply in post to Raw files, then we can highly recommend the RF 16mm F2.8 STM for your ultra-wide-angle and vlogging needs.
-
The Canon RF 16mm f/2.8 STM, like the RF 35mm, 50mm and 85mm primes before it, makes a convincing case for leaving a standard zoom lens out of the shooting equation and sticking to prime numbers.
-
The Canon RF 16mm F2.8 STM opens up wide-angle imaging to more photographers thanks to its $300 price, and delivers more than you'd expect from a low-cost lens.
-
A small, light, bright and exceedingly sharp lens with a wealth of applications, for an exceedingly appealing price.
- Photo Review 8.8/10
Compact, lightweight and affordably-priced, the RF 16mm f/2.8 STM lens would be a worthwhile investment for anyone who needs an ultra-wide prime lens that is compact and easy to carry.
-
The RF 16mm f/2.8 is a lens about compromise. It trades supreme optical quality for a low price and a truly tiny form factor, and I think Canon has done a wonderful job with these compromises.
-
This tiny 16mm lens is a landmark, letting us replace our big ultrawide zooms with this tiny lens. If your other lens starts at 28mm or 24mm you don't need the range between 16mm and 28mm unless you like to carry too much.
-
[I]t fits nicely in their lineup and it gives a lot more options for RF lenses for both crop sensor and full frame.
-
Taking that slight hit in image quality and flaring and and all of that kind of stuff. I think for the price is for me personally, again, I can't speak for everybody else, but I can speak for how I shoot and the things that I want to shoot.
- Photo Feaver 42/50
[T]his lens scored quite high with a score of 42 out of 50, which is a highly recommended lens to have in your camera bag. I would also highly recommend this lens if you're interested in a very small travel lens.
-
I think pretty much everybody should own this lens.
-
Honestly, I am pretty disappointed by this lens, but I guess for the size and weight, the price of this thing, you can't really hate it for having some optical imperfections.
-
So I can highly recommend the lens if you're looking at a wide angle lens or ultra wide angle lens for your Canon system. I think that would be a fabulous investment, I really do, and it's just nice and light.
-
[...] I think the Canon RF 16mm f/2.8 STM is an interesting and unusual lens. Canon manufactured and priced this lens for mass appeal, yet its focal length is rather specialized, which leads me to think that Canon may be playing the long game here with this lens.
-
[...] I think I would definitely recommend this lens. This is so cheap, it costs like 300 US dollars, which is really a joke.
