Canon RF 16mm f/2.8 STM Reviews

Sharp and perfect weight

this little lens gets the job done. I shoot a lot of interiors and this lens is the perfect size to throw in your bag. it's also made gimble shooting a breeze. I had a hard time balancing my 15-35 and instead of paying hundreds for a new gimble I just stuck this little guy on and it was perfect.

Great wide angle lens

I was pleasantly surprised by the image quality of the Canon RF 16 mm f/2.8 STM lens. I have used this lens for a low light indoor event and the images were really nice. I plan to use this lens on a regular basis going forward, so it will always be in my camera bag. It is not weather sealed, but that is not an issue for me. I am very happy to have this lens.

I love this lens! It is a great ultra-wide angle lens that was inexpensive and produces great photos. I love using it as a catch-all lens and has been great in forcing me to move to get the shot I need. I do with it was faster for a prime lens though!

Best budget wide lens for R series

Great for real estate photography

I was considering buying the more expensive 14-35mm zoom lens, but I never or rarely use the zoom function on my APS-C 10-20mm DSLR lens. So I decided to give it a try. I am amazed that I am now able to shoot in tighter rooms and get a good result, something I was not able to do with a 10-20mm APS-C camera lens. For 1/5th the cost I was able to buy a drone instead. Note: I use a CPL and keep it on the camera lens which doubles as a lens protector. It also helps with reducing glare on floors and countertops. If you add a UV filter you will get vignetting. The single CPL filter on the lens works great for me.

Fast, wide and Sharp

By far the worst lens I ever owned

I tried to upload full size 45 MP jpegs from the Canon R5, but the file size is too big. So these 1800 width jpegs will have to do. The lens is sharp in the center, about 1/3 towards the edges. From there on the sharpness goes down quite rapidly. But sharpness (or the lack of it) is only one issue. Lightroom applies distortion correction automatically, without it the distortion would be extreme. I attached a photo where I applied both an X and Y offset of 14.9 to show you how much is corrected digitally. In other words, when you use say a 45MP Canon R5, it will throw away a substantial part of the captured photo and recreate the missing pixels digitally. Next issue is chromatic aberration. The usual automatic CA correction in LR won't do. You have to dial in substantial CA correction using the Defringe slider (often the maximum) to get rid of the nasty purple aberration. However, this can lead to other issues (green fringing), which requires manual fixing (e.g. using the brush tool). I even bought a lens hood to help prevent flair and improve sharpness, but obviously that didn't help. I posted some of the (technically) best photos I could find since there is no point in showing bad photos. The Canon 35mm f/1.8 lens I owned was a sharp lens without CA. If only the 16mm lens would have been half as good, I would have stayed with Canon. In the meantime I sold all my Canon gear as neither the RF 15-35 f/2.8 nor the RF 16 f/2.8 were satisfactory and I needed a sharp wide angle lens. I've switched to a Z7 II and the Z 14-24 f/2.8 lens which are way better in that department.

Nice lightweight ultra wide

I'm glad Canon has been coming out with lightweight, "affordable", "fast"lenses like this one. I have "L" lenses, but for travel and casual shooting I prefer to use lightweight lenses. This does not have the best optics, but I like it for its small size, light weight, price and 2.8 aperture. I can have it in my bag all the time just in case the situation calls out for an ultra wide.
