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, Ricoh GR Digital IV has a
10.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CCD sensor .
Below you can see the Z700EXR and GR Digital IV sensor size comparison.
Sensor Size and Resolution Comparison image of FujiFilm Z700EXR and Ricoh GR Digital IV Cameras
As seen above, Ricoh GR Digital IV has a 1.4x Larger sensor area than FujiFilm Z700EXR. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
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
Ricoh GR Digital IV ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2-inch versus 1/1.7-inch),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
