Focal length equivalents & field of view#
Multiply any focal length by 0.62 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.
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 |
|---|---|
| 23 mm (14 mm eq.) | 35.2 s |
| 32 mm (20 mm eq.) | 25.3 s |
| 39 mm (24 mm eq.) | 20.8 s |
| 57 mm (35 mm eq.) | 14.2 s |
| 81 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 |
|---|---|---|---|
| 39 mm | 1/25 s | 0.3 s | 1.3 s |
| 81 mm | 1/50 s | 1/6 s | 0.6 s |
| 162 mm | 1/100 s | 1/13 s | 0.3 s |
| 324 mm | 1/200 s | 1/25 s | 1/6 s |

Frequently asked questions#
What is the crop factor of the Canon T70?
The Canon T70 has a crop factor of 0.62× relative to 35 mm full frame (diagonal 70.0 mm vs 43.3 mm).
What size is the Canon T70 frame?
51.0 × 48.0 mm (Medium format 53.4 × 40 mm), an area of 2448 mm² — 283% of full frame.
How long can I expose the night sky with the Canon T70?
With a 32 mm lens (20 mm equivalent) the 500 rule gives 25 s.
