GoPro Hero11 Black has a
27.0MP 1/1.9-inch (6.74 x 5.05 mm ) sized CMOS sensor . On the other hand, YI 4K has a
12.0MP (6.17 x 4.55 mm ) sized CMOS sensor and features Ambarella A9SE75 processor.
GoPro Hero11 Black's sensor provides 15MP more than YI 4K's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the Hero11 Black and 4K sensor size comparison.
Sensor Size and Resolution Comparison image of GoPro Hero11 Black and YI 4K Cameras
As seen above, GoPro Hero11 Black has a 1.2x Larger sensor area than YI 4K. 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
GoPro Hero11 Black
or the
YI 4K ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.9-inch versus ),
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.
