For Canon shooters looking to go ultra-wide, there are few native options to choose from. The Canon RF 20mm F1.4 L VCM is Canon’s first ultra-wide prime for the RF mount, and it comes at a time when Canon is expanding VCM lens options – lenses that, to this reviewer, feel like they lean into their videography specs more than stills photography. That said, we took this ultra-wide lens out and used it strictly for photography, and here’s what we found.

The Big Picture: The Canon RF 20mm F1.4 L VCM

Canon’s RF 20mm F1.4 L VCM is one of those lenses that can add character to your image arsenal. While it’s not the widest option out there, there are some benefits to being a lens that’s made by the same manufacturer, with autofocusing being the main one. The RF 20mm F1.4 L’s voice coil motor can quickly and easily jump between focus points with ease. One of the hardest tasks for autofocus lenses is their performance switching between subjects closer to the lens and further back, but the RF 20mm F1.4 L VCM makes it a breeze. It’s true that ultra-wide lenses generally have good-to-great autofocus performance, but this one is setting the standard for any potential third-party lenses in development.
We’re giving the Canon RF 20mm F1.4 L VCM four out of five stars. You can pick one up for yourself – $1699 on Amazon.

- Pro: super snappy autofocus

Experience: Going Wide with the RF 50mm F1.4 L VCM

The Canon RF 50mm F1.4 L VCM was loaned to us by Canon. We used this lens with various cameras, including the Canon EOS R5 and Canon EOS R8 (also on loan from Canon), and the Canon EOS R5 Mark II, which was on loan from LensRentals.

The RF 20mm F1.4 L VCM is a pretty straightforward piece of kit. On the left side of the lens barrel, you’ll find an AF/MF switch, a custom Function button, and an IRIS lock switch. The front of the lens has a nice, rubberized focus ring, and at the bottom (the part closest to the body), there is a clicky aperture ring. Although the lens is very plasticky in feel, there is weather resistance and a metal mount. During our testing, we didn’t get too many bad weather days, but we did find ourselves in a sprinkle or two. The lens brushed off the handful of spot showers and just kept plugging along – unbothered by the elements. That’s something that landscape, street, and nature photographers will undoubtedly love.

Speaking of which, I had the opportunity to take the RF 20mm F1.4 L everywhere, from my regular walks around the city to barbeques to events. In each of these scenarios, the RF 20mm F1.4 has a lot to offer in terms of autofocusing ability. While it’s true that ultra-wide-angle lenses have some of the fastest autofocusing times, an F1.4 that doesn’t “hunt” or breathe while focusing is worth writing home about (or at least reviewing). That’s exactly what you’re getting with the Canon RF 20mm F1.4 L VCM; it’s a truly capable lens that nearly always finds its subject regardless of the lighting conditions or the amount of melanin on the subjects’ faces.
Image Quality
The images that the lens produces have been some of my favorites across the board. Whether I was simply trying to get some high-quality snapshots with friends or at a gig, the lenses are a big reason why it’s hard for me to leave Canon for another camera system. From the way that colors are rendered to the edge-to-edge sharpness with minimal distortion (this is an ultra-wide lens after all), these images are the stuff that keeps pulling you back and wanting to shoot a lot more.

Declaration of Journalistic Intent
The Phoblographer is one of the last standing dedicated photography publications that speaks to both art and tech in our articles. We put declarations up front in our reviews to adhere to journalistic standards that several publications abide by. These help you understand a lot more about what we do:
- At the time of publishing this review, Canon ISNT’ running direct-sold advertising with the Phoblographer. This doesn’t affect our reviews anyway and it never has in our 15 years of publishing our articles. This article is in no way sponsored.
- Note that this isn’t necessarily our final review of the unit. It will be updated, and it’s more of an in-progress review than anything. In fact, almost all our reviews are like this.
- None of the reviews on the Phoblographer are sponsored. That’s against FTC laws and we adhere to them just the same way that newspapers, magazines, and corporate publications do.
- Canon loaned the unit and accessories to the Phoblographer for this review. There was no money exchange between us or their 3rd party partners and the Phoblographer for this to happen. Manufacturers trust the Phoblographer’s reviews, as they are incredibly blunt.
- Canon knows that it cannot influence the site’s reviews. If we don’t like something or if we have issues with it, we’ll let our readers know.
- The Phoblographer’s standards for reviewing products have become much stricter. After having the world’s largest database of real-world lens reviews, we choose not to review anything we don’t find innovative or unique, and in many cases, products that lack weather resistance. Unless something is very unique, we probably won’t touch it.
- In recent years, brands have withheld NDA information from us or stopped working with us because they feel they cannot control our coverage. These days, many brands will not give products to the press unless they get favorable coverage. In other situations, we’ve stopped working with several brands for ethical issues. Either way, we report as honestly and rawly as humanity allows.
- At the time of publishing, the Phoblographer is the only photography publication that is a member of Adobe’s Content Authenticity Initiative. We champion human-made art and are frank with our audience. We are also the only photography publication that labels when an image is edited or not.
