Focal length equivalents & field of view#
Multiply any focal length by 5.69 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 5.3 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.
Diffraction & pixel pitch#
With 1.51 µm pixels, diffraction starts to soften pixel-level detail around f/2.3. For maximum sharpness keep landscapes between f/2.8 and f/2; stopping down further trades detail for depth of field.
| Aperture | Airy disk diameter | Spread over | At 100% view |
|---|---|---|---|
| f/2.8 | 3.8 µm | 2.5 px | slight softening |
| f/4 | 5.4 µm | 3.5 px | visibly soft |
| f/5.6 | 7.5 µm | 5.0 px | visibly soft |
| f/8 | 10.7 µm | 7.1 px | visibly soft |
| f/11 | 14.8 µm | 9.8 px | visibly soft |
| f/16 | 21.5 µm | 14.2 px | visibly soft |
| f/22 | 29.5 µm | 19.5 px | visibly soft |
Maximum print sizes#
At 12.1 MP the Panasonic Lumix DMC-FX77 produces 4,017 × 3,012 pixel images. See the 12 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 13.4 × 10.0 in | 34 × 26 cm |
| 240 DPI | Fine-art inkjet | 16.7 × 12.6 in | 43 × 32 cm |
| 200 DPI | Wall print | 20.1 × 15.1 in | 51 × 38 cm |
| 150 DPI | Poster, viewed from 1 m+ | 26.8 × 20.1 in | 68 × 51 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 |
|---|---|---|---|---|
| 4 mm (23 mm eq.) | 22.0 s | 27.1 s | 35.9 s | 46.4 s |
| 5 mm (28 mm eq.) | 17.6 s | 21.7 s | 28.7 s | 37.1 s |
| 6 mm (34 mm eq.) | 14.6 s | 18.1 s | 23.9 s | 30.9 s |
| 7 mm (40 mm eq.) | 12.5 s | 15.5 s | 20.5 s | 26.5 s |
| 9 mm (51 mm eq.) | 9.8 s | 12.0 s | 15.9 s | 20.6 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 |
|---|---|---|---|
| 4 mm | 1/25 s | 0.3 s | 1.3 s |
| 9 mm | 1/50 s | 1/6 s | 0.6 s |
| 18 mm | 1/100 s | 1/13 s | 0.3 s |
| 35 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Panasonic Lumix DMC-FX77 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 × 5.69.

Frequently asked questions#
What is the crop factor of the Panasonic Lumix DMC-FX77?
The Panasonic Lumix DMC-FX77 has a crop factor of 5.69× relative to 35 mm full frame (diagonal 7.6 mm vs 43.3 mm).
What size is the Panasonic Lumix DMC-FX77 sensor?
6.1 × 4.6 mm (1/2.3"), an area of 28 mm² — 3% of full frame.
Is the Panasonic Lumix DMC-FX77 full frame?
No — its sensor is 1/2.3", which is 31.2× smaller in area than full frame.
How many megapixels does the Panasonic Lumix DMC-FX77 have?
