Focal length equivalents & field of view#
Multiply any focal length by 1.53 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 5.12 µm pixels, diffraction starts to soften pixel-level detail around f/7.6. For maximum sharpness keep landscapes between f/4.2 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 | 1.5 px | sharp |
| f/8 | 10.7 µm | 2.1 px | slight softening |
| f/11 | 14.8 µm | 2.9 px | slight softening |
| f/16 | 21.5 µm | 4.2 px | visibly soft |
| f/22 | 29.5 µm | 5.8 px | visibly soft |
Maximum print sizes#
At 14 MP the Sony Alpha 290 produces 4,592 × 3,056 pixel images. See the 14 megapixel guide or the print size calculator.
| Resolution | Typical use | Inches | Centimetres |
|---|---|---|---|
| 300 DPI | Photo-lab quality | 15.3 × 10.2 in | 39 × 26 cm |
| 240 DPI | Fine-art inkjet | 19.1 × 12.7 in | 49 × 32 cm |
| 200 DPI | Wall print | 23.0 × 15.3 in | 58 × 39 cm |
| 150 DPI | Poster, viewed from 1 m+ | 30.6 × 20.4 in | 78 × 52 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 |
|---|---|---|---|---|
| 9 mm (14 mm eq.) | 36.3 s | 24.1 s | 27.9 s | 32.6 s |
| 13 mm (20 mm eq.) | 25.1 s | 16.7 s | 19.3 s | 22.6 s |
| 16 mm (24 mm eq.) | 20.4 s | 13.5 s | 15.7 s | 18.3 s |
| 23 mm (35 mm eq.) | 14.2 s | 9.4 s | 10.9 s | 12.8 s |
| 33 mm (51 mm eq.) | 9.9 s | 6.6 s | 7.6 s | 8.9 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 |
|---|---|---|---|
| 16 mm | 1/25 s | 0.3 s | 1.3 s |
| 33 mm | 1/50 s | 1/6 s | 0.6 s |
| 65 mm | 1/100 s | 1/13 s | 0.3 s |
| 131 mm | 1/200 s | 1/25 s | 1/6 s |
