Is the canon rf 400mm f 2 8l is usm good for wildlife?

The Canon RF 400mm f/2.8L IS USM is a strong wildlife lens. It's a 400mm prime that stays at f/2.8, with image stabilisation and autofocus. On full frame it frames as 400mm, which suits larger animals and sport from a distance. For birds, the wildlife and sport guide says you want around 600mm full-frame equivalent or more, so this lens is best with a crop body.

On an APS-C Canon RF body it frames like 640mm, which is a good reach for birds. The Canon EOS R7 is one of the APS-C bodies it fits. For full frame, the Canon EOS R5 is a capable pairing for fast subjects.

It's a big, expensive lens, and the guide notes that long lenses hold their value and change hands often. If you're careful about budget, buying used can save a lot. You can see every compatible body on the Canon RF lens page.
