Focal length equivalents & field of view#
Multiply any focal length by 4.71 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 6.4 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 (19 mm eq.) | 26.6 s |
| 5 mm (24 mm eq.) | 21.2 s |
| 6 mm (28 mm eq.) | 17.7 s |
| 7 mm (33 mm eq.) | 15.2 s |
| 11 mm (52 mm eq.) | 9.7 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 |
|---|---|---|---|
| 5 mm | 1/25 s | 0.3 s | 1.3 s |
| 11 mm | 1/50 s | 1/6 s | 0.6 s |
| 21 mm | 1/100 s | 1/13 s | 0.3 s |
| 42 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Nikon Coolpix P340 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 × 4.71.

Frequently asked questions#
What is the crop factor of the Nikon Coolpix P340?
The Nikon Coolpix P340 has a crop factor of 4.71× relative to 35 mm full frame (diagonal 9.2 mm vs 43.3 mm).
What size is the Nikon Coolpix P340 sensor?
7.4 × 5.4 mm (1/1.7"), an area of 40 mm² — 5% of full frame.
Is the Nikon Coolpix P340 full frame?
No — its sensor is 1/1.7", which is 21.5× smaller in area than full frame.
How long can I expose the night sky with the Nikon Coolpix P340?
With a 5 mm lens (24 mm equivalent) the 500 rule gives 21 s.
