The Fujifilm FinePix S1 Pro uses the Nikon F AF mount with a 1.54× crop factor (about 23.3 × 15.6 mm sensor). Below: equivalent focal lengths, maximum shutter speeds for sharp stars, a hyperfocal distance chart, compatible lenses and how to check the shutter count.

NPF = (35 × f-number + 30 × pixel pitch) ÷ focal length, with a pixel pitch of 3.9 µm (typical for this format — exact resolution not in our database). The strict version (Michaud's detailed NPF for the galactic core) gives pin-point stars at 100% view; the 500 rule is a loose rule of thumb that shows trailing on modern sensors.

Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp (circle of confusion 0.0194 mm). Use the hyperfocal calculator for other settings.

How to check the Fujifilm FinePix S1 Pro shutter count
Fujifilm records an image counter (ImageCount) in MakerNotes on many X-series bodies; it counts frames rather than mechanical actuations. Run `exiftool -ImageCount image.raf`.
ExifTool tag: ImageCount. Always test an original, unedited file straight from the card.
