Leica Q3 43 has a
60.0MP Full frame (36 x 24 mm ) sized BSI-CMOS sensor and features Maestro IV processor. On the other hand, Sony RX1R III has a
61.0MP Full frame (35.8 x 23.8 mm ) sized BSI-CMOS sensor and features Bionz XR processor.
Another similarity between these two cameras is that both Sony RX1R III and Leica Q3 43 sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the Q3 43 and RX1R III sensor size comparison.
Sensor Size and Resolution Comparison image of Leica Q3 43 and Sony RX1R III Cameras
Leica Q3 43 and Sony RX1R III 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
Leica Q3 43
or the
Sony RX1R III ,
including hyperfocal distance.
