Canon 1Ds has a
11.0MP Full frame (35.8 x 23.8 mm ) sized CMOS sensor . On the other hand, Canon R6 II has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Digic X processor.
Canon R6 II's sensor provides 13MP more than Canon 1Ds'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 1Ds and R6 II sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1Ds and Canon R6 II Cameras
Canon 1Ds and Canon R6 II 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 1Ds
or the
Canon R6 II ,
including hyperfocal distance.
