Focal length equivalents & field of view#
Multiply any focal length by 6.40 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.

Depth of field table#
Total depth of field at each subject distance, using a circle of confusion of 4.7 µm (the 0.030 mm full-frame standard scaled by the crop factor).

Equivalent aperture#
Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.
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. (NPF needs a known resolution and is omitted here.)
| Focal length | 500 rule |
|---|---|
| 4 mm (26 mm eq.) | 19.5 s |
| 5 mm (32 mm eq.) | 15.6 s |
| 6 mm (38 mm eq.) | 13.0 s |
| 7 mm (45 mm eq.) | 11.2 s |
| 8 mm (51 mm eq.) | 9.8 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 |
|---|---|---|---|
| 4 mm | 1/25 s | 0.3 s | 1.3 s |
| 8 mm | 1/50 s | 1/6 s | 0.6 s |
| 16 mm | 1/100 s | 1/13 s | 0.3 s |
| 31 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Ricoh Caplio RR30 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 × 6.40.

Frequently asked questions#
What is the crop factor of the Ricoh Caplio RR30?
The Ricoh Caplio RR30 has a crop factor of 6.40× relative to 35 mm full frame (diagonal 6.8 mm vs 43.3 mm).
What size is the Ricoh Caplio RR30 sensor?
5.3 × 4.2 mm (1/2.5"), an area of 22 mm² — 3% of full frame.
Is the Ricoh Caplio RR30 full frame?
No — its sensor is 1/2.5", which is 39.0× smaller in area than full frame.
How long can I expose the night sky with the Ricoh Caplio RR30?
With a 5 mm lens (32 mm equivalent) the 500 rule gives 16 s.
