Nikon B600 has a
16.0MP 1/2.3 (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Sony A700 has a
12.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor .
Below you can see the B600 and A700 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon B600 and Sony A700 Cameras
As seen above, Sony A700 has a 13.1x Larger sensor area than Nikon B600. 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
Nikon B600
or the
Sony A700 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3 versus APS-C),
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.
