GoPro Hero5 Black has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor . On the other hand, GoPro Hero9 Black has a
23.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features GP1 processor.
GoPro Hero9 Black's sensor provides 11MP more than GoPro Hero5 Black'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 Hero5 Black and Hero9 Black sensor size comparison.
Sensor Size and Resolution Comparison image of GoPro Hero5 Black and GoPro Hero9 Black Cameras
GoPro Hero5 Black and GoPro Hero9 Black 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
GoPro Hero5 Black
or the
GoPro Hero9 Black ,
including hyperfocal distance.
