Focal length equivalents & field of view#
Multiply any focal length by 2.73 to get the full-frame field of view. For fixed-lens cameras use the real focal length printed on the lens (e.g. “6.1–18.3 mm”), not the 35 mm equivalent.

Equivalent aperture#
Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.
Diffraction & pixel pitch#
With 2.44 µm pixels, diffraction starts to soften pixel-level detail around f/3.6. For maximum sharpness keep landscapes between f/2.8 and f/4; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 1.5 px | sharp |
| f/4 | 5.4 µm | 2.2 px | slight softening |
| f/5.6 | 7.5 µm | 3.1 px | visibly soft |
| f/8 | 10.7 µm | 4.4 px | visibly soft |
| f/11 | 14.8 µm | 6.0 px | visibly soft |
| f/16 | 21.5 µm | 8.8 px | visibly soft |
| f/22 | 29.5 µm | 12.1 px | visibly soft |
Maximum print sizes#
At 20.2 MP the DxO Labs ONE produces 5,406 × 3,604 pixel images. See the 20 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 18.0 × 12.0 in | 46 × 31 cm |
| 240 DPI | Fine-art inkjet | 22.5 × 15.0 in | 57 × 38 cm |
| 200 DPI | Wall print | 27.0 × 18.0 in | 69 × 46 cm |
| 150 DPI | Poster, viewed from 1 m+ | 36.0 × 24.0 in | 92 × 61 cm |
Night-sky exposure limits#
Longest exposure before stars trail. The NPF rule accounts for pixel pitch and is stricter than the classic 500 rule — use it for pin-sharp stars on high-resolution sensors.
| Focal length | 500 rule | NPF f/1.8 | NPF f/2.8 | NPF f/4 |
|---|---|---|---|---|
| 5 mm (14 mm eq.) | 36.7 s | 27.3 s | 34.3 s | 42.7 s |
| 7 mm (19 mm eq.) | 26.2 s | 19.5 s | 24.5 s | 30.5 s |
| 9 mm (25 mm eq.) | 20.4 s | 15.1 s | 19.0 s | 23.7 s |
| 13 mm (35 mm eq.) | 14.1 s | 10.5 s | 13.2 s | 16.4 s |
| 18 mm (49 mm eq.) | 10.2 s | 7.6 s | 9.5 s | 11.8 s |
Handheld shutter speed guide#
The reciprocal rule uses the equivalent focal length. High-resolution sensors may need one stop faster than this for pixel-sharp results.
| Focal length | No stabilisation (1/equiv. focal) | With 3-stop IS | With 5-stop IBIS |
|---|---|---|---|
| 9 mm | 1/25 s | 0.3 s | 1.3 s |
| 18 mm | 1/50 s | 1/6 s | 0.6 s |
| 37 mm | 1/100 s | 1/13 s | 0.3 s |
| 73 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The DxO Labs ONE has a built-in, non-interchangeable lens. Use the real focal length of that lens with the tables above; its full-frame equivalent is that number × 2.73.

Frequently asked questions#
What is the crop factor of the DxO Labs ONE?
The DxO Labs ONE has a crop factor of 2.73× relative to 35 mm full frame (diagonal 15.9 mm vs 43.3 mm).
What size is the DxO Labs ONE sensor?
13.2 × 8.8 mm (1" (one-inch)), an area of 116 mm² — 13% of full frame.
Is the DxO Labs ONE full frame?
No — its sensor is 1" (one-inch), which is 7.4× smaller in area than full frame.
How many megapixels does the DxO Labs ONE have?
20.2 megapixels (5,406 × 3,604 pixels), enough for a 18 × 12 inch print at 300 DPI.
How long can I expose the night sky with the DxO Labs ONE?
With a 7 mm lens (19 mm equivalent) the 500 rule gives 26 s and the stricter NPF rule at f/2.8 gives 24 s.
