Best Canon camera for bird photography? 10 bodies compared by pixels on the bird

Which Canon camera puts the most pixels on a bird? Every Canon body with a guide on this site, on the same 600 mm lens, at the same distances, so the only thing that changes is the sensor.

Pixels on the bird with a 600 mm lens

Pixels across the bird from beak to tail with a 600 mm lens on every body, using the bird lengths in our reach calculator, most pixels first:

“Won't fit” means the bird is longer than the frame is wide at that distance. The sum, as in every guide: the bird's length × focal length ÷ (distance − focal length) gives its size on the sensor, divided by the pixel pitch. Each guide also shows its body with the lenses most often paired with it.

What the table shows

On the same lens at the same distance, the bird's image on the sensor is the same size on every body, so reach comes down to how many pixels fit across it: the pixel pitch. The Canon EOS 90D and Canon EOS R7 have the smallest pixels here (3.20 µm), so they put 1.87 times as many pixels across the bird as the Canon EOS R3 (6.00 µm): 1,842 against 984 across an American robin at 25 m.

Megapixels alone don't measure reach. The 20-megapixel Canon EOS 7D Mark II puts more pixels on the bird than the 44.8-megapixel Canon EOS R5 (1,442 against 1,343 across the robin), because its pixels are smaller (4.09 µm against 4.39).

The 1.6x crop mode on the R5, R6 Mark II, R8 and R3 doesn't add reach: it records the middle of the frame, so the bird fills more of a smaller picture with exactly the same pixels across it.

Bodies that share a sensor size and pixel count put exactly the same pixels on the bird with the same lens: the 90D and R7 (22.3 mm and 6,960 pixels across); the R10 and R50 (22.3 mm and 6,000 pixels across); the R6 Mark II and R8 (35.9 mm and 6,000 pixels across).

The R6 Mark II, R8 and R3 all record 6,000 pixels across; the gap of under 1% between the R6 Mark II and R8 and the R3 comes only from the sensor widths in Canon's spec sheets (35.9 mm against 36.0 mm).

Across all 39 interchangeable-lens bodies with a guide on this site, on the same 600 mm lens, only the Panasonic Lumix G9 II, Fujifilm X-H2 and Fujifilm X-T5 put more pixels on the bird than the Canon EOS 90D and Canon EOS R7 (1,970, 1,941 and 1,941 across the robin at 25 m, against 1,842).

To see two bodies side by side with your own lens, distance and bird, the reach calculator opens comparing the 90D and the R3. It runs in the browser.

Lens guides: RF 100-400mm, RF 100-500mm, RF 200-800mm and Sigma 150-600mm.

BirdFrame for Mac finds every bird in a folder or Photos album and crops each from the full-size original, thousands at once.

Questions

Which Canon camera puts the most pixels on a bird?

On the same lens, the Canon EOS 90D and Canon EOS R7 (3.20 µm pixels): about 1,842 pixels across an American robin at 25 m with a 600 mm lens. The Canon EOS R3 puts 984 across the same robin, so the 90D has 1.87 times as many. That's reach only; autofocus, burst rate and handling aren't measured here.

Do more megapixels mean more reach?

Not by themselves. On the same lens, reach comes down to pixel pitch: the 20-megapixel Canon EOS 7D Mark II (4.09 µm) puts 1,442 pixels across an American robin at 25 m with 600 mm, and the 44.8-megapixel Canon EOS R5 (4.39 µm) 1,343.

Does an APS-C Canon camera give more reach than full frame?

On the same lens, yes, but because of pixel size, not sensor size. Every APS-C Canon body here has smaller pixels than every full-frame one, so each puts more pixels across the bird: 1,442 to 1,842 across an American robin at 25 m with 600 mm, against 984 to 1,343 on the full-frame bodies. A full-frame body records more of the scene around the bird.

Does a full-frame Canon's 1.6x crop mode add reach?

No. It records the middle of the frame, so the bird looks bigger in a smaller picture, but it gets exactly the same pixels. The R5 guide shows it: 1,115 pixels across an American robin at 25 m with 500 mm, in the full frame or in 1.6x crop mode.
