Sensor size compared#
Focal length equivalents & field of view#
Multiply any focal length by 0.65 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.
Diffraction & pixel pitch#
With 17.96 µm pixels, diffraction starts to soften pixel-level detail around f/26.8. For maximum sharpness keep landscapes between f/14.7 and f/27; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 0.2 px | sharp |
| f/4 | 5.4 µm | 0.3 px | sharp |
| f/5.6 | 7.5 µm | 0.4 px | sharp |
| f/8 | 10.7 µm | 0.6 px | sharp |
| f/11 | 14.8 µm | 0.8 px | sharp |
| f/16 | 21.5 µm | 1.2 px | sharp |
| f/22 | 29.5 µm | 1.6 px | sharp |
Maximum print sizes#
At 10.1 MP the Panasonic Lumix DMC-LX7 produces 3,648 × 2,736 pixel images. See the 10 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 12.2 × 9.1 in | 31 × 23 cm |
| 240 DPI | Fine-art inkjet | 15.2 × 11.4 in | 39 × 29 cm |
| 200 DPI | Wall print | 18.2 × 13.7 in | 46 × 35 cm |
| 150 DPI | Poster, viewed from 1 m+ | 24.3 × 18.2 in | 62 × 46 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 |
|---|---|---|---|---|
| 21 mm (14 mm eq.) | 36.4 s | 28.7 s | 30.3 s | 32.3 s |
| 31 mm (20 mm eq.) | 24.7 s | 19.4 s | 20.5 s | 21.9 s |
| 37 mm (24 mm eq.) | 20.7 s | 16.3 s | 17.2 s | 18.3 s |
| 54 mm (35 mm eq.) | 14.2 s | 11.1 s | 11.8 s | 12.6 s |
| 77 mm (50 mm eq.) | 9.9 s | 7.8 s | 8.3 s | 8.8 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 |
|---|---|---|---|
| 37 mm | 1/25 s | 0.3 s | 1.3 s |
| 77 mm | 1/50 s | 1/6 s | 0.6 s |
| 153 mm | 1/100 s | 1/13 s | 0.3 s |
| 306 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Panasonic Lumix DMC-LX7 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 × 0.65.
Frequently asked questions#
What is the crop factor of the Panasonic Lumix DMC-LX7?
The Panasonic Lumix DMC-LX7 has a crop factor of 0.65× relative to 35 mm full frame (diagonal 66.2 mm vs 43.3 mm).
What size is the Panasonic Lumix DMC-LX7 sensor?
65.5 × 9.7 mm (65.5 × 9.7 mm), an area of 635 mm² — 74% of full frame.
Is the Panasonic Lumix DMC-LX7 full frame?
No — its sensor is larger than full frame (medium format).
How many megapixels does the Panasonic Lumix DMC-LX7 have?
10.1 megapixels (3,648 × 2,736 pixels), enough for a 12 × 9 inch print at 300 DPI.
How long can I expose the night sky with the Panasonic Lumix DMC-LX7?
With a 31 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 21 s.
