Popular for its reach and flexibility, the Canon RF 70-200mm f/4 L IS USM is a fresh take on this well-regarded focal length, featuring an impressively sleek and lightweight form factor perfect for their full-frame mirrorless cameras. The constant f/4 maximum aperture strikes a balance between being bright enough for available light shooting while also contributing to the especially portable, handholdable design. Complementing this is an apt Optical Image Stabilizer, which compensates for up to 5 stops of camera shake, or up to an impressive 7.5 stops of shake correction when paired with an EOS R-type body with IBIS.
Optically, this lens incorporates four UD elements, which suppress a variety of aberrations throughout the zoom range for high clarity, and an Air Sphere Coating is also featured to reduce flare and ghosting. Balancing the distinguished optical system is a Dual Nano USM focus system, which delivers fast, nearly silent autofocus performance with full-time manual focus override. Additionally, this 70-200mm is weather-sealed and has a fluorine coating to protect the front and rear elements.

Canon RF 70-200mm f/4L IS USM Reviews
A very sharp lens
This lens produces very sharp images and the constant f4 even when zoomed to 200mm is great for mid-light conditions without the need for additional lighting or flash systems. As with all Canon L lenses, the quality and workmanship of is excellent.
This is a great lens!
Amazing Lens. I recently made the transition from EF to RF after years of being a staunch EF supporter. The first time I shot the R3, I was hooked for good. My problem was I had/have 12 EOS EF lenses I didn’t know what to do with. My first non-RF lens purchase was the Canon EF to RF converter so my inventory of EF lenses wouldn’t go to waste. For the most part, the converter does the job admirably. All the lens functions transfer; the AF works just as fast and crisp gives me the tack-sharp images I expect from Canon. My EF 70-200mm f/2.8 was the exception. For some reason, it just doesn’t work well with the converter. Through several iterations of EOS EF cameras from the 1Dx Mark II through the 5DS series, that lens was pretty much my workhorse……………… Well, that and the EF 24-70 f/2.8. So I checked the data sheets and the reviews on the RF 70-200 f/2.8 as well as the less expensive f/4.0 and discovered how favorably the f/4.0 lens was viewed. So before buying one, I got a loaner from Canon Professional Services and shot it for 10 days, and was incredibly surprised by its performance. The first thing you notice is how smaller and lighter it is from its big brother, and I must confess, I have always been a lens status snob believing the only way to go was f/2.8 whenever possible. So my collection of EF 200, 300 and 600mm lenses, which could have put a Porsche in my garage instead of a Ford Edge, caused me to turn my nose down at f/4.0 or f/6.3 lenses. Big mistake. In reality, if I had to be honest, I can’t remember a single shooting event in the years I’ve been a photographer, where I any of the 2.8 lenses gave me an advantage over the competition. Yes, they are more expensive. Yes they have more glass, but this RF 70-200 f/4.0 has shown me it’s as good in every way as its higher priced brother. I immediately bought one from B&H after the loan period was over and am completely satisfied. This is a great lens, and should be in very serious photographer’s bag.
