A Review of the Canon RF 100-400mm f/5.6-8 IS USM Lens

A 100-400mm zoom lens is highly versatile, useful for anything from sports and wildlife photography to landscape work and more. They come in many different options with a wide variety of price points. Canon's RF 100-400mm f/5.6-8 IS USM sits at the affordable end of the spectrum but still offers some great features, and this excellent video review takes a look at the performance and image quality you can expect from it in practice. 

Coming to you from Gordon Laing, this great video review takes a look at the Canon RF 100-400mm f/5.6-8 IS USM lens. Though this lens has a narrow variable maximum aperture, we have seen Canon's f/11 primes demonstrate that when used in tandem with a modern body, such a lens can actually be a perfectly acceptable performer and comes with advantages like a portable size and affordable price (in this case, $649). Of course, such lenses work best with decent light, but if you are not working in extreme scenarios or if you just want a longer lens for occasional shots, this can be the perfect solution that will not break the bank. Check out the video above for Laing's full thoughts on the lens.

My Fuji X-T3 loses a lot of AF performance at apertures smaller than F5.6. Do the Canons handle F8 fine?

I can't speak for anything but the f11 800mm. The focus points are constrained to the center, but auto focus is super fast at f11 on my eos r body.

Purchased lens in Sept. It has proven to be an excellent lens paired with a R6.
