Focal length equivalents & field of view#
Multiply any focal length by 5.60 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 1.41 µm pixels, diffraction starts to soften pixel-level detail around f/2.1. 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 | 2.7 px | slight softening |
| f/4 | 5.4 µm | 3.8 px | visibly soft |
| f/5.6 | 7.5 µm | 5.3 px | visibly soft |
| f/8 | 10.7 µm | 7.6 px | visibly soft |
| f/11 | 14.8 µm | 10.5 px | visibly soft |
| f/16 | 21.5 µm | 15.3 px | visibly soft |
| f/22 | 29.5 µm | 21.0 px | visibly soft |
Maximum print sizes#
At 14.1 MP the Panasonic Lumix DMC-FZ45 produces 4,320 × 3,240 pixel images. See the 14 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 14.4 × 10.8 in | 37 × 27 cm |
| 240 DPI | Fine-art inkjet | 18.0 × 13.5 in | 46 × 34 cm |
| 200 DPI | Wall print | 21.6 × 16.2 in | 55 × 41 cm |
| 150 DPI | Poster, viewed from 1 m+ | 28.8 × 21.6 in | 73 × 55 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 (22 mm eq.) | 22.3 s | 26.3 s | 35.1 s | 45.6 s |
| 5 mm (28 mm eq.) | 17.9 s | 21.0 s | 28.0 s | 36.4 s |
| 6 mm (34 mm eq.) | 14.9 s | 17.5 s | 23.4 s | 30.4 s |
| 7 mm (39 mm eq.) | 12.8 s | 15.0 s | 20.0 s | 26.0 s |
| 9 mm (50 mm eq.) | 9.9 s | 11.7 s | 15.6 s | 20.2 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 |
|---|---|---|---|
| 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 |
| 36 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The Panasonic Lumix DMC-FZ45 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 × 5.60.

What size is the Panasonic Lumix DMC-FZ45 sensor?
6.1 × 4.8 mm (1/2.3"), an area of 29 mm² — 3% of full frame.
Is the Panasonic Lumix DMC-FZ45 full frame?
No — its sensor is 1/2.3", which is 29.8× smaller in area than full frame.
How many megapixels does the Panasonic Lumix DMC-FZ45 have?
