Fujifilm GFX100RF

The Fujifilm GFX100RF is a compact with a Medium format 44 × 33 mm sensor measuring 45.0 × 30.0 mm. Its crop factor is 0.80× — wider than full frame, so a 50 mm lens frames like 40 mm. Every number below is calculated for this exact sensor.

Focal length equivalents & field of view#

Multiply any focal length by 0.80 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.)

18 mm (14 mm eq.)34.7 s
25 mm (20 mm eq.)25.0 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 Fujifilm GFX100RF 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 × 0.80.

Frequently asked questions#

What is the crop factor of the Fujifilm GFX100RF?

The Fujifilm GFX100RF has a crop factor of 0.80× relative to 35 mm full frame (diagonal 54.1 mm vs 43.3 mm).

What size is the Fujifilm GFX100RF sensor?

45.0 × 30.0 mm (Medium format 44 × 33 mm), an area of 1350 mm² — 156% of full frame.

Is the Fujifilm GFX100RF full frame?

No — its sensor is larger than full frame (medium format).

How long can I expose the night sky with the Fujifilm GFX100RF?

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