FujiFilm Z700EXR 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 F770EXR has a
16.0MP 1/2-inch (6.4 x 4.8 mm ) sized EXRCMOS sensor and features EXR processor.
Below you can see the Z700EXR and F770EXR sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm Z700EXR and Fujifilm F770EXR Cameras
FujiFilm Z700EXR and Fujifilm F770EXR 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 Z700EXR has 32% larger pixel area compared to Fujifilm F770EXR, 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 Z700EXR
or the
Fujifilm F770EXR ,
including hyperfocal distance.
