Both DJI Pocket 2 and Samsung Galaxy Camera have 16.0 MP resolution sensors but DJI Pocket 2's sensor is 1/1.7-inch (7.6 x 5.7 mm ) and Samsung Galaxy Camera's sensor is 1/2.3-inch (6.17 x 4.55 mm ).
Since DJI Pocket 2's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Samsung Galaxy Camera.
Below you can see the Pocket 2 and Galaxy Camera sensor size comparison.
Sensor Size and Resolution Comparison image of DJI Pocket 2 and Samsung Galaxy Camera Cameras
As seen above, DJI Pocket 2 has a 1.5x Larger sensor area than Samsung Galaxy Camera. 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
DJI Pocket 2
or the
Samsung Galaxy Camera ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.7-inch 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.
