Nikon B700 has a
20.0MP 1/2.3 (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Olympus SZ-31MR iHS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features Dual TruePic V processor.
Below you can see the B700 and SZ-31MR iHS sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon B700 and Olympus SZ-31MR iHS Cameras
Nikon B700 and Olympus SZ-31MR iHS 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.
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
Nikon B700
or the
Olympus SZ-31MR iHS ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3 versus 1/2.3-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.
