Focal length equivalents & field of view#

Multiply any focal length by 1.00 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.

Depth of field table#

Total depth of field at each subject distance, using a circle of confusion of 30.0 µm (the 0.030 mm full-frame standard scaled by the crop factor). Detailed tables: 24 mm f/1.8, 24 mm f/2.8, 35 mm f/1.8, 35 mm f/2.8, 50 mm f/1.8, 50 mm f/2.8.

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 length500 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.

Lens#

The Nikon S3 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 × 1.00.

Frequently asked questions#

What is the crop factor of the Nikon S3?

The Nikon S3 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 Nikon S3 sensor?

36.0 × 24.0 mm (Full frame (35 mm)), an area of 864 mm² — 100% of full frame.

Is the Nikon S3 full frame?

Yes — its sensor is the same 36 × 24 mm size as 35 mm film.

How long can I expose the night sky with the Nikon S3?

With a 20 mm lens (20 mm equivalent) the 500 rule gives 25 s.
