Focal length equivalents & field of view#
Multiply any focal length by 5.64 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 1.34 µm pixels, diffraction starts to soften pixel-level detail around f/2.0. For maximum sharpness keep landscapes between f/2.8 and f/2; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 2.8 px | slight softening |
| f/4 | 5.4 µm | 4.0 px | visibly soft |
| f/5.6 | 7.5 µm | 5.6 px | visibly soft |
| f/8 | 10.7 µm | 8.0 px | visibly soft |
| f/11 | 14.8 µm | 11.0 px | visibly soft |
| f/16 | 21.5 µm | 16.0 px | visibly soft |
| f/22 | 29.5 µm | 22.0 px | visibly soft |
Maximum print sizes#
At 16 MP the Olympus Tough TG-4 produces 4,608 × 3,456 pixel images. See the 16 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 15.4 × 11.5 in | 39 × 29 cm |
| 240 DPI | Fine-art inkjet | 19.2 × 14.4 in | 49 × 37 cm |
| 200 DPI | Wall print | 23.0 × 17.3 in | 59 × 44 cm |
| 150 DPI | Poster, viewed from 1 m+ | 30.7 × 23.0 in | 78 × 59 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 |
|---|---|---|---|---|
| 4 mm (23 mm eq.) | 22.1 s | 25.8 s | 34.5 s | 45.0 s |
| 5 mm (28 mm eq.) | 17.7 s | 20.6 s | 27.6 s | 36.0 s |
| 6 mm (34 mm eq.) | 14.8 s | 17.2 s | 23.0 s | 30.0 s |
| 7 mm (40 mm eq.) | 12.7 s | 14.7 s | 19.7 s | 25.7 s |
| 9 mm (51 mm eq.) | 9.8 s | 11.5 s | 15.4 s | 20.0 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 |
|---|---|---|---|
| 4 mm | 1/25 s | 0.3 s | 1.3 s |
| 9 mm | 1/50 s | 1/6 s | 0.6 s |
| 18 mm | 1/100 s | 1/13 s | 0.3 s |
| 35 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Olympus Tough TG-4 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 × 5.64.

Frequently asked questions#
What is the crop factor of the Olympus Tough TG-4?
The Olympus Tough TG-4 has a crop factor of 5.64× relative to 35 mm full frame (diagonal 7.7 mm vs 43.3 mm).
What size is the Olympus Tough TG-4 sensor?
6.2 × 4.5 mm (1/2.3"), an area of 28 mm² — 3% of full frame.
Is the Olympus Tough TG-4 full frame?
No — its sensor is 1/2.3", which is 30.8× smaller in area than full frame.
How many megapixels does the Olympus Tough TG-4 have?
16 megapixels (4,608 × 3,456 pixels), enough for a 15 × 12 inch print at 300 DPI.
How long can I expose the night sky with the Olympus Tough TG-4?
With a 5 mm lens (28 mm equivalent) the 500 rule gives 18 s and the stricter NPF rule at f/2.8 gives 28 s.
