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

Which Sony camera puts the most pixels on a bird? Every Sony 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 Sony A7R VI has the smallest pixels here (3.60 µm), so it puts 1.65 times as many pixels across the bird as the Sony A9 III (5.93 µm): 1,641 against 995 across an American robin at 25 m.

Megapixels alone don't measure reach. The 24-megapixel Sony A6400 puts more pixels on the bird than the 49.8-megapixel Sony A1 (1,507 against 1,420 across the robin), because its pixels are smaller (3.92 µm against 4.16).

Sensor size by itself doesn't add reach either. The APS-C Sony A6700 (3.76 µm) and the full-frame Sony A7R V (3.76 µm) have pixels of nearly the same size, so on the same lens they put nearly the same pixels across the bird (1,568 and 1,571 on the robin); the full-frame body records more of the scene around it.

A full-frame body's APS-C crop mode 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 A6400 and A6600 (23.5 mm and 6,000 pixels across); the A1 and A1 II (35.9 mm and 8,640 pixels across); the A7 IV and A7 V (35.9 mm and 7,008 pixels across).

Across all 39 interchangeable-lens bodies with a guide on this site, on the same 600 mm lens, 10 bodies from other makers put more pixels on the bird than the Sony A7R VI, led by the Panasonic Lumix G9 II with 3.00 µm pixels (1,970 across the robin at 25 m).

Sony's RX10 IV has a built-in zoom (600 mm in 35mm terms, 220 mm real), so it can't take the same lens; it is compared at full zoom on the bridge camera page.

To see two bodies side by side with your own lens, distance and bird, the reach calculator opens comparing the A7R VI and the A9 III. It runs in the browser.

Lens guides: FE 100-400mm, FE 200-600mm 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 Sony camera puts the most pixels on a bird?

On the same lens, the Sony A7R VI (3.60 µm pixels): about 1,641 pixels across an American robin at 25 m with a 600 mm lens. The Sony A9 III puts 995 across the same robin, so the A7R VI has 1.65 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 24-megapixel Sony A6400 (3.92 µm) puts 1,507 pixels across an American robin at 25 m with 600 mm, and the 49.8-megapixel Sony A1 (4.16 µm) 1,420.

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

Only if its pixels are smaller. On the same 600 mm lens, the APS-C bodies here put 1,507 to 1,568 pixels across an American robin at 25 m and the full-frame bodies 995 to 1,641; the full-frame Sony A7R VI (3.60 µm) and A7R V (3.76 µm) both beat every APS-C body here because their pixels are smaller, the A7R V only just (1,571 against 1,568 on the A6700). A full-frame body records more of the scene around the bird.

Does a full-frame Sony's APS-C 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 A7R VI guide shows it: 1,641 pixels across an American robin at 25 m with 600 mm, in the full frame or in APS-C crop mode.
