The Canon RF 70-200mm f/4L IS USM is an outstanding telephoto zoom lens. It’s extremely compact, built well, and produces images with very high quality. The lens is sharp, with good bokeh, low chromatic aberration and good control of other lens aberrations. It’s really an excellent little package.
As with a lot of RF lenses, the biggest downside is the price. At $1,599, it’s a very expensive lens for an f/4 telezoom, and $300 more than the newest EF version of the lens. What you get in return for the price is what is perhaps the ultimate travel telephoto: a constant aperture lens that is barely larger than an f/4 standard zoom and will fit easily into almost any bag. It’s another great addition to the RF lens lineup.
