Focal length equivalents & field of view#

Multiply any focal length by 6.33 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.)

4 mm (25 mm eq.)19.7 s
5 mm (32 mm eq.)15.8 s
6 mm (38 mm eq.)13.2 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 Fujifilm FinePix S304 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 × 6.33.

Frequently asked questions#

What is the crop factor of the Fujifilm FinePix S304?

The Fujifilm FinePix S304 has a crop factor of 6.33× relative to 35 mm full frame (diagonal 6.8 mm vs 43.3 mm).

What size is the Fujifilm FinePix S304 sensor?

5.3 × 4.3 mm (1/2.5"), an area of 23 mm² — 3% of full frame.

Is the Fujifilm FinePix S304 full frame?

No — its sensor is 1/2.5", which is 37.8× smaller in area than full frame.

How long can I expose the night sky with the Fujifilm FinePix S304?

With a 5 mm lens (32 mm equivalent) the 500 rule gives 16 s.
