FujiFilm F300EXR 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 F900EXR has a
16.0MP 1/2-inch (6.4 x 4.8 mm ) sized EXRCMOS sensor and features EXR II processor.
Below you can see the F300EXR and F900EXR sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm F300EXR and Fujifilm F900EXR Cameras
FujiFilm F300EXR and Fujifilm F900EXR 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 F300EXR has 32% larger pixel area compared to Fujifilm F900EXR, it has potential to collect more light on pixel level hence 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 F300EXR
or the
Fujifilm F900EXR ,
including hyperfocal distance.
