Focal length equivalents & field of view#
Multiply any focal length by 5.58 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 5.4 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 (22 mm eq.) | 22.4 s |
| 5 mm (28 mm eq.) | 17.9 s |
| 6 mm (33 mm eq.) | 14.9 s |
| 7 mm (39 mm eq.) | 12.8 s |
| 9 mm (50 mm eq.) | 10.0 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 | 1/20 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 |
| 36 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Panasonic DMC-ZS40 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 × 5.58.

Frequently asked questions#
What is the crop factor of the Panasonic DMC-ZS40?
The Panasonic DMC-ZS40 has a crop factor of 5.58× relative to 35 mm full frame (diagonal 7.8 mm vs 43.3 mm).
What size is the Panasonic DMC-ZS40 sensor?
6.2 × 4.7 mm (1/2.3"), an area of 29 mm² — 3% of full frame.
Is the Panasonic DMC-ZS40 full frame?
No — its sensor is 1/2.3", which is 30.0× smaller in area than full frame.
How long can I expose the night sky with the Panasonic DMC-ZS40?
With a 5 mm lens (28 mm equivalent) the 500 rule gives 18 s.
