Sony FDR-X3000 has a
8.0MP (1/2. ) sized BSI-CMOS sensor and features Bionz X processor. On the other hand, DJI Osmo Action 3 has a
12.0MP 1/1.7-inch (7.6 x 5.7 mm ) sized CMOS sensor .
Below you can see the FDR-X3000 and Osmo Action 3 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony FDR-X3000 and DJI Osmo Action 3 Cameras
As seen above, DJI Osmo Action 3 has a infx Larger sensor area than Sony FDR-X3000. 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
Sony FDR-X3000
or the
DJI Osmo Action 3 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
( 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.
