Nikon Coolpix P950 for bird photography: the numbers, worked out

What the Nikon Coolpix P950 puts on a bird, worked out from its sensor and its built-in zoom: pixels across birds from chickadee to heron at 25, 50 and 100 m, what those pixels can and can't show, how far you can crop and still meet iNaturalist and contest sizes, and how much the wingtips blur in flight.

The Nikon Coolpix P1000 has the same sensor and pixel count; its zoom reaches 3,000 mm in 35mm terms instead of 2,000 (P1000 guide).

Nikon's spec sheet gives the sensor as the 1/2.3-inch type rather than in millimetres; the tools use that type's usual 6.17 × 4.55 mm.

Pixels on the bird at 25, 50 and 100 m

Pixels across the bird from beak to tail at two zoom settings, in 35mm terms (2,000 mm equiv. is 357 mm real, 1,000 mm equiv. is 179 mm), using the bird lengths in our reach calculator:

“Won't fit” means the bird is longer than the frame is wide at that distance. The sum uses the real focal length: the bird's length × focal length ÷ (distance − focal length) gives its size on the sensor, divided by the 1.34 µm pixel pitch. The P950's zoom is 4.3–357 mm real, 24–2,000 mm in 35mm terms (Nikon's spec sheet), so both tools divide a 35mm-equivalent focal length by 5.602 to get the real one.

More pixels on the bird than a big camera, but not more detail

At full zoom the P950 puts more pixels on a bird than a large-sensor camera with a 600 mm lens: 1,289 across an American robin at 50 m, against 691 on a Nikon Z50II and 670 on a Nikon Z8 with the Z 180-600mm at 600 mm (same calculator, same robin, same distance). That's because its pixels are tiny: 1.34 µm, against 4.35 µm on the Z8.

Detail is a different matter. At full zoom the P950's lens is 357 mm at f/6.5 (Nikon's spec sheet), so its opening is 357 ÷ 6.5 = 55 mm across; the Z 180-600mm at 600 mm f/6.3 opens to 95 mm. At f/6.5, diffraction alone spreads each point of light into a blur spot (the Airy disk, out to its first dark ring) about 9 µm across in green light, the width of about 7 of the P950's pixels, so neighbouring pixels can't hold separate detail. Even with a perfect lens, the 1,289 pixels across the robin hold less detail than the Z8's 670, and the smaller opening collects about a third as much light from the bird, so at the same shutter speed it looks noisier. Use these pixel counts for sizes and contest minimums, not as a promise of feather detail.

Detail here means the finest pattern each camera records at half contrast (MTF50) with a perfect lens, worked out from diffraction at the stated f-number and the pixel size: about 188 line pairs across the robin for the P950 and 247 for the Z8 with 600 mm at f/6.3. Real lenses record less, especially a zoom at full stretch.

How far you can crop and still meet real sizes

Nearly every size rule counts pixels on the long edge. Here is the smallest share of the P950's 4,608-pixel width that a horizontal crop can keep for each, and how much of that crop an American robin at 50 m at full zoom (1,289 px) would fill:

So with this robin you can crop until it fills 43% of the width and still have Audubon's 3,000 pixels. Crop tighter and the file drops below the size; enlarging it to reach the number adds no detail, and the contests that ask for full-size files say so (crop rules and minimum sizes for 11 contests). For the general case, see how much you can crop a bird photo. The rule that always holds: crop from the full-size original, never from a downsized export, and never upscale.

Birds in flight: wingtip blur at 1/2000 and 1/4000

From our shutter-speed calculator, at full zoom (2,000 mm in 35mm terms), panning with the bird, wingtips measured mid-stroke where they move fastest:

Wingbeat rates for the osprey and bald eagle are estimates (est.), so treat these as close guides rather than exact figures. Holding the osprey's wingtips within 3 pixels at this distance would take about 1/10000; for the bald eagle, about 1/8000. Nikon's spec sheet lists 1/2000 as the P950's top speed, with 1/4000 only in S and M modes at the wide end of the zoom with a small aperture, so at full zoom the 1/4000 column shows what that speed would do rather than a setting you can pick. The wings slow to a stop at the top and bottom of each stroke, which is why a burst catches sharp wingtips that a single frame usually misses.

Try it with your own birds

The reach calculator and the shutter-speed calculator open pre-set to the P950 at full zoom; enter the zoom in 35mm terms (up to 2,000 mm) and change the distance or bird to see your own numbers. Both run in the browser.

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

Questions

How many pixels does the Nikon Coolpix P950 put on a bird?

It depends on the zoom and the distance. At full zoom (2,000 mm in 35mm terms, 357 mm real), about 1,289 pixels across an American robin at 50 m and 642 at 100 m; at 1,000 mm equivalent, 642 and 321. The sum: the bird's length × real focal length ÷ (distance − focal length), divided by the pixel pitch (1.34 µm).

How far can you crop a P950 photo for iNaturalist or a contest?

A horizontal crop has to keep 44% of the frame's width to fill iNaturalist's 2,048 pixels, 65% for Audubon's 3,000-pixel entries and 76% for Australian Geographic's 3,500-pixel finalist files (2026 rules). Crop from the full-size original and never enlarge a crop to reach a size.

Does the P950 out-reach a camera with a 600 mm lens?

In pixels, yes: at full zoom it puts about 1,289 pixels across an American robin at 50 m, against 670 on a Nikon Z8 with a 600 mm lens. In detail, no: at full zoom (357 mm at f/6.5) diffraction spreads each point of light over about 7 of its pixels, so even with a perfect lens its 1,289 pixels hold less detail than the Z8's 670, and its 55 mm opening collects about a third the light of a 600 mm f/6.3 lens's 95 mm.

What shutter speed freezes a bird in flight with the P950?

With an osprey at about 150 m at full zoom, wings across two thirds of the frame, the wingtips blur about 13 pixels at 1/2000 mid-stroke when you pan with the bird. Holding them within 3 pixels would take about 1/10000, and the P950's top speed at full zoom is 1/2000, so a burst is what catches the wings sharp near the top or bottom of the stroke. Wingbeat rates for the osprey and bald eagle are estimates.
