Focal length equivalents & field of view#
Multiply any focal length by 1.52 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 4.81 µm pixels, diffraction starts to soften pixel-level detail around f/7.2. For maximum sharpness keep landscapes between f/3.9 and f/7; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 0.8 px | sharp |
| f/4 | 5.4 µm | 1.1 px | sharp |
| f/5.6 | 7.5 µm | 1.6 px | sharp |
| f/8 | 10.7 µm | 2.2 px | slight softening |
| f/11 | 14.8 µm | 3.1 px | visibly soft |
| f/16 | 21.5 µm | 4.5 px | visibly soft |
| f/22 | 29.5 µm | 6.1 px | visibly soft |
Maximum print sizes#
At 16 MP the Ricoh GR (large sensor compact camera) produces 4,928 × 3,264 pixel images. See the 16 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 16.4 × 10.9 in | 42 × 28 cm |
| 240 DPI | Fine-art inkjet | 20.5 × 13.6 in | 52 × 35 cm |
| 200 DPI | Wall print | 24.6 × 16.3 in | 63 × 41 cm |
| 150 DPI | Poster, viewed from 1 m+ | 32.9 × 21.8 in | 83 × 55 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.) | 36.5 s | 23.0 s | 26.9 s | 31.6 s |
| 13 mm (20 mm eq.) | 25.3 s | 15.9 s | 18.6 s | 21.9 s |
| 16 mm (24 mm eq.) | 20.5 s | 13.0 s | 15.1 s | 17.8 s |
| 23 mm (35 mm eq.) | 14.3 s | 9.0 s | 10.5 s | 12.4 s |
| 33 mm (50 mm eq.) | 10.0 s | 6.3 s | 7.3 s | 8.6 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 |
| 66 mm | 1/100 s | 1/13 s | 0.3 s |
| 131 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Ricoh GR (large sensor compact camera) 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 × 1.52.

Frequently asked questions#
What is the crop factor of the Ricoh GR (large sensor compact camera)?
The Ricoh GR (large sensor compact camera) has a crop factor of 1.52× relative to 35 mm full frame (diagonal 28.4 mm vs 43.3 mm).
What size is the Ricoh GR (large sensor compact camera) sensor?
23.7 × 15.7 mm (APS-C), an area of 372 mm² — 43% of full frame.
Is the Ricoh GR (large sensor compact camera) full frame?
No — its sensor is APS-C, which is 2.3× smaller in area than full frame.
How many megapixels does the Ricoh GR (large sensor compact camera) have?
16 megapixels (4,928 × 3,264 pixels), enough for a 16 × 11 inch print at 300 DPI.
How long can I expose the night sky with the Ricoh GR (large sensor compact camera)?
With a 13 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 19 s.
