Focal length equivalents & field of view#
Multiply any focal length by 0.71 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 42.2 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 |
|---|---|
| 20 mm (14 mm eq.) | 35.2 s |
| 28 mm (20 mm eq.) | 25.1 s |
| 34 mm (24 mm eq.) | 20.7 s |
| 49 mm (35 mm eq.) | 14.4 s |
| 70 mm (50 mm eq.) | 10.1 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 |
|---|---|---|---|
| 34 mm | 1/25 s | 0.3 s | 1.3 s |
| 70 mm | 1/50 s | 1/6 s | 0.6 s |
| 141 mm | 1/100 s | 1/13 s | 0.3 s |
| 282 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Panon Shoko Widelux 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 × 0.71.
Frequently asked questions#
What is the crop factor of the Panon Shoko Widelux?
The Panon Shoko Widelux has a crop factor of 0.71× relative to 35 mm full frame (diagonal 60.9 mm vs 43.3 mm).
What size is the Panon Shoko Widelux sensor?
56.0 × 24.0 mm (56.0 × 24.0 mm), an area of 1344 mm² — 156% of full frame.
Is the Panon Shoko Widelux full frame?
No — its sensor is larger than full frame (medium format).
How long can I expose the night sky with the Panon Shoko Widelux?
With a 28 mm lens (20 mm equivalent) the 500 rule gives 25 s.
