Focal length equivalents & field of view#
Multiply any focal length by 1.35 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.
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. (NPF needs a known resolution and is omitted here.)
| Focal length | 500 rule |
|---|---|
| 10 mm (13 mm eq.) | 37.1 s |
| 15 mm (20 mm eq.) | 24.8 s |
| 18 mm (24 mm eq.) | 20.6 s |
| 26 mm (35 mm eq.) | 14.3 s |
| 37 mm (50 mm eq.) | 10.0 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 |
|---|---|---|---|
| 18 mm | 1/25 s | 0.3 s | 1.3 s |
| 37 mm | 1/50 s | 1/6 s | 0.6 s |
| 74 mm | 1/100 s | 1/13 s | 0.3 s |
| 149 mm | 1/200 s | 1/25 s | 1/6 s |
