With class-leading portability and performance, the RF mount Canon RF 600mm F4L IS USM is also set to be a kitbag essential for pro nature photographers. When paired with the Canon EOS R3, the RF 600mm F4L IS III USM is enhanced for bird photography via the camera's animal AF setting which prioritises birds, as well as the new Flexi Zone AF, which enables you to customise the AF area size and shape – particularly helpful for shooting smaller birds.
For super-telephoto wildlife photography on a budget, also consider the Canon RF 600mm F11 IS STM – or even the Canon RF 800mm F11 IS STM. "Up until now, 800mm lenses have been too expensive, and they've just been too big and heavy – you have to plan to go out to shoot with them," explains Mike. "But here's a lens that's lighter than a bottle of water, which you can keep in your bag all of the time.”
Previously under EF design parameters it was only really possible to go to f/5.6, John notes, "but as we've seen with the RF 600mm F11 IS STM, RF 800mm F11 IS STM and RF 200-800mm F6.3-9 IS USM lenses, you can now make new types of wildlife lenses within an affordable price range and convenient size. Being able to take advantage of the ability of Dual Pixel CMOS AF to focus down to f/22 makes new lens concepts possible.
"With wildlife photography, you're often focusing on small animals and birds, and it's difficult to create impact because they quite easily blend into the background. But these new lenses can help you fill the frame and capture impressive images."
