Focal length equivalents & field of view#
Multiply any focal length by 2.00 to get the full-frame field of view. Angles are for a rectilinear lens focused at infinity.

Equivalent aperture#
Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.
Diffraction & pixel pitch#
With 5.52 µm pixels, diffraction starts to soften pixel-level detail around f/8.2. For maximum sharpness keep landscapes between f/4.5 and f/8; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 0.7 px | sharp |
| f/4 | 5.4 µm | 1.0 px | sharp |
| f/5.6 | 7.5 µm | 1.4 px | sharp |
| f/8 | 10.7 µm | 1.9 px | sharp |
| f/11 | 14.8 µm | 2.7 px | slight softening |
| f/16 | 21.5 µm | 3.9 px | visibly soft |
| f/22 | 29.5 µm | 5.4 px | visibly soft |
Maximum print sizes#
At 7.4 MP the Leica Digilux 3 produces 3,136 × 2,352 pixel images. See the 8 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 10.5 × 7.8 in | 27 × 20 cm |
| 240 DPI | Fine-art inkjet | 13.1 × 9.8 in | 33 × 25 cm |
| 200 DPI | Wall print | 15.7 × 11.8 in | 40 × 30 cm |
| 150 DPI | Poster, viewed from 1 m+ | 20.9 × 15.7 in | 53 × 40 cm |
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.
| Focal length | 500 rule | NPF f/1.8 | NPF f/2.8 | NPF f/4 |
|---|---|---|---|---|
| 7 mm (14 mm eq.) | 35.7 s | 32.6 s | 37.6 s | 43.6 s |
| 10 mm (20 mm eq.) | 25.0 s | 22.8 s | 26.3 s | 30.5 s |
| 12 mm (24 mm eq.) | 20.8 s | 19.0 s | 22.0 s | 25.5 s |
| 18 mm (36 mm eq.) | 13.9 s | 12.7 s | 14.6 s | 17.0 s |
| 25 mm (50 mm eq.) | 10.0 s | 9.1 s | 10.5 s | 12.2 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 |
|---|---|---|---|
| 12 mm | 1/25 s | 0.3 s | 1.3 s |
| 25 mm | 1/50 s | 1/6 s | 0.6 s |
| 50 mm | 1/100 s | 1/13 s | 0.3 s |
| 100 mm | 1/200 s | 1/25 s | 1/6 s |
