Focal length equivalents & field of view#
Multiply any focal length by 0.81 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 22.12 µm pixels, diffraction starts to soften pixel-level detail around f/33.0. For maximum sharpness keep landscapes between f/18.1 and f/33; 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 | 0.2 px | sharp |
| f/5.6 | 7.5 µm | 0.3 px | sharp |
| f/8 | 10.7 µm | 0.5 px | sharp |
| f/11 | 14.8 µm | 0.7 px | sharp |
| f/16 | 21.5 µm | 1.0 px | sharp |
| f/22 | 29.5 µm | 1.3 px | sharp |
Maximum print sizes#
At 4.1 MP the HP Photosmart M407 produces 2,396 × 1,766 pixel images. See the 4 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 8.0 × 5.9 in | 20 × 15 cm |
| 240 DPI | Fine-art inkjet | 10.0 × 7.4 in | 25 × 19 cm |
| 200 DPI | Wall print | 12.0 × 8.8 in | 30 × 22 cm |
| 150 DPI | Poster, viewed from 1 m+ | 16.0 × 11.8 in | 41 × 30 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 |
|---|---|---|---|---|
| 17 mm (14 mm eq.) | 36.3 s | 42.7 s | 44.8 s | 47.3 s |
| 25 mm (20 mm eq.) | 24.7 s | 29.1 s | 30.5 s | 32.1 s |
| 30 mm (24 mm eq.) | 20.6 s | 24.2 s | 25.4 s | 26.8 s |
| 43 mm (35 mm eq.) | 14.4 s | 16.9 s | 17.7 s | 18.7 s |
| 62 mm (50 mm eq.) | 10.0 s | 11.7 s | 12.3 s | 13.0 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 |
|---|---|---|---|
| 30 mm | 1/25 s | 0.3 s | 1.3 s |
| 62 mm | 1/50 s | 1/6 s | 0.6 s |
| 124 mm | 1/100 s | 1/13 s | 0.3 s |
| 247 mm | 1/200 s | 1/25 s | 1/6 s |
Lens#
The HP Photosmart M407 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 × 0.81.
Frequently asked questions#
What is the crop factor of the HP Photosmart M407?
The HP Photosmart M407 has a crop factor of 0.81× relative to 35 mm full frame (diagonal 53.5 mm vs 43.3 mm).
What size is the HP Photosmart M407 sensor?
53.0 × 7.0 mm (53.0 × 7.0 mm), an area of 371 mm² — 43% of full frame.
Is the HP Photosmart M407 full frame?
No — its sensor is larger than full frame (medium format).
How many megapixels does the HP Photosmart M407 have?
4.1 megapixels (2,396 × 1,766 pixels), enough for a 8 × 6 inch print at 300 DPI.
How long can I expose the night sky with the HP Photosmart M407?
With a 25 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 30 s.
