The Leica D-Lux 8 uses the built-in lens (fixed-lens camera) with a 2.21× crop factor (about 16.3 × 10.9 mm sensor). Below: equivalent focal lengths, maximum shutter speeds for sharp stars, a hyperfocal distance chart and how to check the shutter count.

Milky Way exposure: NPF and 500 rule

NPF = (35 × f-number + 30 × pixel pitch) ÷ focal length, with a pixel pitch of 2.4 µm (typical for this format — exact resolution not in our database). The strict version (Michaud's detailed NPF for the galactic core) gives pin-point stars at 100% view; the 500 rule is a loose rule of thumb that shows trailing on modern sensors.
Hyperfocal distance chart
| Focal length | f/2.8 | f/5.6 | f/8 | f/11 | f/16 |
|---|---|---|---|---|---|
| 10 mm | 2.6 m | 1.3 m | 0.9 m | 0.7 m | 0.5 m |
| 14 mm | 5.2 m | 2.6 m | 1.8 m | 1.3 m | 0.9 m |
| 16 mm | 6.7 m | 3.4 m | 2.4 m | 1.7 m | 1.2 m |
| 18 mm | 8.5 m | 4.3 m | 3.0 m | 2.2 m | 1.5 m |
| 20 mm | 11 m | 5.3 m | 3.7 m | 2.7 m | 1.9 m |
| 24 mm | 15 m | 7.6 m | 5.3 m | 3.9 m | 2.7 m |
| 28 mm | 21 m | 10 m | 7.2 m | 5.3 m | 3.6 m |
| 35 mm | 32 m | 16 m | 11 m | 8.2 m | 5.7 m |
Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp (circle of confusion 0.0136 mm). Use the hyperfocal calculator for other settings.
How to check the Leica D-Lux 8 shutter count
Some Leica M and SL bodies show the count in the camera's service or info menu; EXIF support varies by model.
ExifTool tag: (varies). Always test an original, unedited file straight from the card.
