Focal length equivalents & field of view#
Multiply any focal length by 1.53 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 4.33 µm pixels, diffraction starts to soften pixel-level detail around f/6.5. For maximum sharpness keep landscapes between f/3.6 and f/6; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 0.9 px | sharp |
| f/4 | 5.4 µm | 1.2 px | sharp |
| f/5.6 | 7.5 µm | 1.7 px | sharp |
| f/8 | 10.7 µm | 2.5 px | slight softening |
| f/11 | 14.8 µm | 3.4 px | visibly soft |
| f/16 | 21.5 µm | 5.0 px | visibly soft |
| f/22 | 29.5 µm | 6.8 px | visibly soft |
Maximum print sizes#
At 19.6 MP the Sigma dp0 Quattro produces 5,424 × 3,616 pixel images. See the 20 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 18.1 × 12.1 in | 46 × 31 cm |
| 240 DPI | Fine-art inkjet | 22.6 × 15.1 in | 57 × 38 cm |
| 200 DPI | Wall print | 27.1 × 18.1 in | 69 × 46 cm |
| 150 DPI | Poster, viewed from 1 m+ | 36.2 × 24.1 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 |
|---|---|---|---|---|
| 9 mm (14 mm eq.) | 36.3 s | 21.4 s | 25.3 s | 30.0 s |
| 13 mm (20 mm eq.) | 25.1 s | 14.8 s | 17.5 s | 20.8 s |
| 16 mm (24 mm eq.) | 20.4 s | 12.1 s | 14.2 s | 16.9 s |
| 23 mm (35 mm eq.) | 14.2 s | 8.4 s | 9.9 s | 11.7 s |
| 33 mm (51 mm eq.) | 9.9 s | 5.8 s | 6.9 s | 8.2 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 |
|---|---|---|---|
| 16 mm | 1/25 s | 0.3 s | 1.3 s |
| 33 mm | 1/50 s | 1/6 s | 0.6 s |
| 65 mm | 1/100 s | 1/13 s | 0.3 s |
| 131 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Sigma dp0 Quattro 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 × 1.53.

Frequently asked questions#
What is the crop factor of the Sigma dp0 Quattro?
The Sigma dp0 Quattro has a crop factor of 1.53× relative to 35 mm full frame (diagonal 28.3 mm vs 43.3 mm).
What size is the Sigma dp0 Quattro sensor?
23.5 × 15.7 mm (APS-C), an area of 369 mm² — 43% of full frame.
Is the Sigma dp0 Quattro full frame?
No — its sensor is APS-C, which is 2.3× smaller in area than full frame.
How many megapixels does the Sigma dp0 Quattro have?
19.6 megapixels (5,424 × 3,616 pixels), enough for a 18 × 12 inch print at 300 DPI.
How long can I expose the night sky with the Sigma dp0 Quattro?
With a 13 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 18 s.
