Focal length equivalents & field of view#
Multiply any focal length by 1.00 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 |
|---|---|
| 14 mm (14 mm eq.) | 35.7 s |
| 20 mm (20 mm eq.) | 25.0 s |
| 24 mm (24 mm eq.) | 20.8 s |
| 35 mm (35 mm eq.) | 14.3 s |
| 50 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 |
|---|---|---|---|
| 24 mm | 1/25 s | 0.3 s | 1.3 s |
| 50 mm | 1/50 s | 1/6 s | 0.6 s |
| 100 mm | 1/100 s | 1/13 s | 0.3 s |
| 200 mm | 1/200 s | 1/25 s | 1/6 s |

Frequently asked questions#
What is the crop factor of the Leica SL3-S?
The Leica SL3-S has a crop factor of 1.00× relative to 35 mm full frame (diagonal 43.3 mm vs 43.3 mm).
What size is the Leica SL3-S sensor?
36.0 × 24.0 mm (Full frame (35 mm)), an area of 864 mm² — 100% of full frame.
Is the Leica SL3-S full frame?
Yes — its sensor is the same 36 × 24 mm size as 35 mm film.
What lens mount does the Leica SL3-S use?
The Leica SL3-S uses the L-Mount (flange distance 20.00 mm).
How long can I expose the night sky with the Leica SL3-S?
With a 20 mm lens (20 mm equivalent) the 500 rule gives 25 s.
