Which camera is best for bird photography?

For bird photography, my pick is the OM System OM-1 Mark II. It has a 20.4-megapixel Micro Four Thirds sensor, very good bird detection, and a light kit, which matters when you're carrying a long lens into the field. It's a wildlife favourite for good reason.

If you shoot full frame, look at the Canon EF 400mm f/5.6L USM. It's a light, fast-focusing birding prime. It has no stabilisation, so you'll want decent light or a steady support.

If you're buying used, go through the checks in Buying used, especially the shutter count, since a bird shooter's camera gets a lot of use.
