The Fujifilm FinePix S5600 uses the built-in lens (fixed-lens camera) with a 6.03× crop factor (about 6.0 × 4.0 mm sensor). Below: equivalent focal lengths, maximum shutter speeds for sharp stars, a hyperfocal distance chart and how to check the shutter count.
Equivalent focal length & field of view
| Lens focal length | Full-frame equivalent | Diagonal FOV | Horizontal FOV |
|---|---|---|---|
| 8 mm | 48 mm | 48.5° | 41.1° |
| 10 mm | 60 mm | 39.7° | 33.4° |
| 12 mm | 72 mm | 33.4° | 28.1° |
| 14 mm | 84 mm | 28.9° | 24.2° |
| 16 mm | 96 mm | 25.4° | 21.2° |
| 18 mm | 109 mm | 22.7° | 18.9° |
| 20 mm | 121 mm | 20.4° | 17.1° |
| 24 mm | 145 mm | 17.1° | 14.3° |
| 28 mm | 169 mm | 14.7° | 12.2° |
| 35 mm | 211 mm | 11.8° | 9.8° |
| 50 mm | 302 mm | 8.2° | 6.9° |
| 85 mm | 513 mm | 4.9° | 4.0° |
| 135 mm | 814 mm | 3.1° | 2.5° |
Multiply by the 6.03× crop factor for the full-frame equivalent field of view.
Milky Way exposure: NPF and 500 rule
| Focal length | NPF @ f/1.8 | NPF @ f/2.8 | Strict NPF @ f/2.8 | 500 rule |
|---|---|---|---|---|
| 8 mm | 16.9 s | 21.2 s | 11.6 s | 10.4 s |
| 10 mm | 13.5 s | 17.0 s | 9.3 s | 8.3 s |
| 12 mm | 11.2 s | 14.2 s | 7.7 s | 6.9 s |
NPF = (35 × f-number + 30 × pixel pitch) ÷ focal length, with a pixel pitch of 2.4 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.
Hyperfocal distance chart
| Focal length | f/2.8 | f/5.6 | f/8 | f/11 | f/16 |
|---|---|---|---|---|---|
| 10 mm | 7.2 m | 3.6 m | 2.5 m | 1.8 m | 1.3 m |
Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp (circle of confusion 0.005 mm). Use the hyperfocal calculator for other settings.
How to check the Fujifilm FinePix S5600 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.
