After using it for a while, I am excited to share my personal experience with this lens.
I must say that I am thoroughly impressed with the Canon RF100-400mm. The lens is perfect for wildlife photography and outdoor activities, especially hiking. One of the major selling points for me was its lightweight design, which made it easy to carry around without getting tired. The autofocus is fast and very accurate, thanks to Canon’s Nano USM technology. Also, the minimum focusing distance of 2.89 feet at 200mm is impressive, and the maximum magnification of 0.41x at 400mm is excellent.
The image stabilization system is also top-notch, with up to 5.5 stops of shake correction. When paired with an EOS R series camera featuring In-Body Image Stabilizer (IBIS), the shake correction increases to up to 6 stops. I was able to capture stunning shots without any blur, even when shooting handheld.
The lens is compatible only with Canon’s full-frame mirrorless R series cameras, which could be a downside for some people. However, it’s worth noting that this lens pairs well with the Canon RF 1.4X extender, bringing out the long end of the lens to 560mm at F11, which is an excellent focal range for wildlife photography.
