Canon R6 V has a
32.5MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor. On the other hand, Blackmagic PYXIS 12K has a
98.8MP Full frame (35.6 x 23.3 mm ) sized CMOS sensor .
Blackmagic PYXIS 12K's sensor provides 66.3MP more than Canon R6 V'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 R6 V and PYXIS 12K sensor size comparison.
Sensor Size and Resolution Comparison image of Canon R6 V and Blackmagic PYXIS 12K Cameras
Canon R6 V and Blackmagic PYXIS 12K have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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
Canon R6 V
or the
Blackmagic PYXIS 12K ,
including hyperfocal distance.
