FujiFilm F80EXR has a
12.0MP 1/2-inch (6.4 x 4.8 mm ) sized CCD sensor and features EXR processor. On the other hand, FujiFilm F70EXR has a
10.0MP 1/2-inch (6.4 x 4.8 mm ) sized CCD sensor and features EXR processor.
Below you can see the F80EXR and F70EXR sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm F80EXR and FujiFilm F70EXR Cameras
FujiFilm F80EXR and FujiFilm F70EXR have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since FujiFilm F70EXR has 22% larger pixel area (3.13µm 2 vs 2.56µm 2 ) compared to FujiFilm F80EXR, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
FujiFilm F80EXR
or the
FujiFilm F70EXR ,
including hyperfocal distance.
