100-400mm lenses have long been popular for everything from bird photography to sports, as they offer a tremendously useful focal length range. While Canon offers a premium option of this lens, there is the much more affordable RF 100-400mm f/5.6-8 IS USM for anyone who wants to save some money or a bit of weight in their bag, and this great video review takes a look at the lens and the sort of performance and image quality you can expect from it in practice.
Coming to you from Brent Hall, this excellent video review takes a look at the Canon RF 100-400mm f/5.6-8 IS USM lens. A few years ago, such a lens might be relatively unusable, but with the advances in high-ISO performance and autofocus, we have seen even lenses like the 600mm f/11 and 800mm f/11 perform perfectly well. This makes the 100-400mm f/5.6-8 a potentially attractive option, especially given its affordable price ($649) and small footprint. No doubt, such a lens is going to have some trouble when the light becomes scarce, but if you are shooting mostly during the day, it could be a perfectly acceptable choice. Check out the video above for Hall's full thoughts on the lens.
