Fujifilm FinePix X100

The Fujifilm FinePix X100 is a compact with a APS-C sensor measuring 23.6 × 15.8 mm. Its crop factor is 1.52×, so a 50 mm lens frames like 76 mm on full frame. Every number below is calculated for this exact sensor.

Focal length equivalents & field of view#

Multiply any focal length by 1.52 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.)

9 mm (14 mm eq.)36.5 s
13 mm (20 mm eq.)25.3 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 X100 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 × 1.52.

Frequently asked questions#

What is the crop factor of the Fujifilm FinePix X100?

The Fujifilm FinePix X100 has a crop factor of 1.52× relative to 35 mm full frame (diagonal 28.4 mm vs 43.3 mm).

What size is the Fujifilm FinePix X100 sensor?

23.6 × 15.8 mm (APS-C), an area of 373 mm² — 43% of full frame.

Is the Fujifilm FinePix X100 full frame?

No — its sensor is APS-C, which is 2.3× smaller in area than full frame.

How long can I expose the night sky with the Fujifilm FinePix X100?

With a 13 mm lens (20 mm equivalent) the 500 rule gives 25 s.
