Focal length equivalents & field of view#
Multiply any focal length by 2.21 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.
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 |
|---|---|
| 6 mm (13 mm eq.) | 37.7 s |
| 9 mm (20 mm eq.) | 25.1 s |
| 11 mm (24 mm eq.) | 20.6 s |
| 16 mm (35 mm eq.) | 14.1 s |
| 23 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 |
|---|---|---|---|
| 11 mm | 1/25 s | 0.3 s | 1.3 s |
| 23 mm | 1/50 s | 1/6 s | 0.6 s |
| 45 mm | 1/100 s | 1/13 s | 0.3 s |
| 90 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Leica D-Lux 7 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 × 2.21.

Frequently asked questions#
What is the crop factor of the Leica D-Lux 7?
The Leica D-Lux 7 has a crop factor of 2.21× relative to 35 mm full frame (diagonal 19.6 mm vs 43.3 mm).
What size is the Leica D-Lux 7 sensor?
17.3 × 9.2 mm (Four Thirds / Micro Four Thirds), an area of 158 mm² — 18% of full frame.
Is the Leica D-Lux 7 full frame?
No — its sensor is Four Thirds / Micro Four Thirds, which is 5.5× smaller in area than full frame.
How long can I expose the night sky with the Leica D-Lux 7?
With a 9 mm lens (20 mm equivalent) the 500 rule gives 25 s.
