Both Leica SL3-S and Leica SL have Full frame sized 24.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Another similarity between these two cameras is that both Leica SL and Leica SL3-S 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 SL3-S and SL sensor size comparison.
Sensor Size and Resolution Comparison image of Leica SL3-S and Leica SL Cameras
Leica SL3-S and Leica SL 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
Leica SL3-S
or the
Leica SL ,
including hyperfocal distance.
