Review: Canon RF 16mm f/2.8 STM by Christopher Frost
- Thread starter Canon Rumors Guy
- Start date
Wasn't the RF mount supposed to allow easier engineering of better designs without these optical weaknesses? Watching this review, the way the focus sounds like the original nifty fifty... It feels like they just slapped this together for lowest possible cost.
Meanwhile, I'm kicking myself. Two years ago I had a chance to purchase a 24-70 F/4 for $550, and I thought... meh, that's kinda pricey. Now it's going for $1200 on ebay from reputable places. The 16-35 F/4 is also skyrocketing. Maybe supply disruptions are a part of this, but there's still so much demand in good EF lenses, and they're optically no worse than the RF versions. Is Canon leaving money on the table?

Christopher is also one of my favourite lens reviewers along with Dustin Abbott. This review is kind of what I was expecting on this compact cheap lens, no wow’s but still a nice little bit of glass.
My pre-order is in-store now, I’ll be picking it up on Thursday this week. I didn’t expect this lens to compete with my Sigma 14-24 f/2.8 but for a cheap compact wide lens that you’ll hardly know you have on your camera and isn’t going to put your back out when using it, I can live with its spots and pimples.

Well, $300 is a pretty low cost, relatively speaking. I really do think Canon is planning on launching a sub-$800 FF EOS R, and the RP is now $1000. Having an inexpensive FF body with only costly lenses for it is not a recipe for success. But consider – the combination of the RF 16/2.8, RF 24-105 non-L, and RF 100-400 gives a user a very large focal range for a $1350 outlay.

No. They make some very fine and expensive lenses for the nerds who are allergic to corrections, and they make some lenses that perform nicely as an engineered system for people who want to take great pictures with a light and inexpensive lens.
Then again, those $100,000 Mercedes S-class sedans drive like crap with all the computerized traction control systems turned off. Can't Mercedes design a decent car anymore? I also hear the U.S. Air Force has some planes that won't even fly without computers ensuring stability. Talk about a step backward! Why can't they all be as smart as me and design things right?

This was the first lens I ever pre-ordered as soon as it was available and didn't think twice. Got it last week and took it to a concert, and I am pretty pleased. I've been using a Tokina 11-16 2.8 for about 10 years now, even as I moved to full frame and could only use it as a 16mm prime for the most part, so I've been on the lookout for a replacement for quite some time. Not having to use the RF adapter and having a 16mm that is 1/3 the size and maybe 1/5 the weight... it's a revelation. And the images so far have been pretty good. Like the review says, it's dead sharp in the middle, which for my purposes is all I need, since i use it in situations when the subject is up close and I just want a wide frame. for $300 this is a no brainer.

There are huge big heavy expensive super-corrected lenses, and then there are small, simple lenses like this 16/2.8. There is a purpose for each. The 16/2.8 will be a perfect travel/backpacking lens. I will be getting one. The pre-corrected barrel distortion doesn't bother me at all. I think it is quite a clever trick actually. If it helps reduce size, weight and cost, then I'm all for it.
I do hope Canon develops more lenses in this spirit. For example, it'd be nice if they made an R-mount version of the classic 50/1.4 with double-gauss design rather than the big heavy Sigma 50/1.4 versions. All that would be needed is a modern AF motor, improved coatings, and perhaps a tweak to the optical formula. Yes I know we already have a 50/1.8 in R mount but 1.4 would be nice.

Yes, and we’ve already seen plenty of evidence of this with lenses such as the 28-70mm F2 and the 100mm macro. But they are expensive optics, and when the original R was launched there were endless complaints that Canon didn’t cater for the budget end of the market.
Now they have a near-complete set of exotic L glass AND an excellent selection of budget glass covering everything from 16mm to 800mm. And some people still complain…
This is a $300 lens, it’s pretty unrealistic to expect it to be as smooth and quiet in operation as an L lens.
It’s designed to be a *cheap* and pocketable lens that can be carried at all times and takes up virtually no space in a camera bag.
Sure, they could easily have put a few more elements in the lens and avoided the need for computational aberration correction, they could also have put in a better focus motor, and included optical stabilisation. But if they did it would weigh 5 times as much and cost 5 times more.

My Audi at half that price has the four wheels under so much computer control that I don’t think you can turn much of it off, mostly just for driving in ice or something. The feel that the computer control gives when going over hilly, twisty roads is great, as if I knew what I am doing. You can set various components of that control to suit for a custom setup, and not just a choice for everything at once between Sport and regular Drive modes.
I am glad that my G5X II doesn’t have the extra pound of glass it would take to correct the little lens to an acceptable level without software corrections. I bet the owners of the little 16mm lens will feel the same way.

I have the lens too and I’m quite happy for my use cases.
For selfie I don’t care about corner sharpness, but all other aberrations are perfectly controlled.
For astro I won’t use the lens corrections but light frames to deal with vignetting .. no one cares about straight lines for Milky Way photography so I actually get sharpness and contrast where I need it. Coma is fairly okay, worst case I have to stop it down to f4 .. still better then the EF 16-35mm f4L for Milky Way I reckon, it had more aberrations traded for better corner sharpness.
Big plus for the smooth bokeh and close focusing distance!
most annoying is actually the lack of weather proofing, despite its small size I’d like to leave it out for Astro for a couple of hours and don’t have to take it down during a small drizzle.

Yes, Christopher Frost is an excellent unbiased reviewer, as are Gordon Laing and Dustin Abbott.
It’s nice to listen to people who can produce a video without jumping up and down shouting “BREAKING NEWS!” like Tony Northrup, and without jabbering at 20 words per second, waving their arms all over the place and talking nonsense like Kai.
Having said that, I do find Jared Polin to be very informative and entertaining, and I have a soft spot for Chris and Jordan on dpreview.

I’ve had this lens for a week now and I really love it. The only complaint I would make would be the distortion but it’s easily fixed in post and with in body corrections so it’s not a real issue.
The size and weight of this means when I travel it can come everywhere and just be used when something is too wide for the RF 35mm!

Just looking at the image quality comparisons at the-digital-picture.com and the corrected lens results actually look pretty good in the corners (as well as everywhere else). I guess it depends on what you expect - plus I think some anti-auto correct bias happening. In the corners, it's a lot better than the EF 17-40 L lens, for example. And at f/4 only a very slight (negative) difference (at least to my eye) with the EF 16-35 f/4 in the corners. Very slight. The corners are, of course, softer corrected than uncorrected, and this is causing a lot of negativity, in my opinion.

And there are small great lens just like EF 40mm 2.8 and EF-s 24mm 2.8.
This one is not good.
