Leica CL has a
24.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features Maestro II processor. On the other hand, Sony A6700 has a
26.0MP APS-C (23.5 x 15.6 mm ) sized BSI-CMOS sensor and features Bionz XR processor.
Below you can see the CL and A6700 sensor size comparison.
Sensor Size and Resolution Comparison image of Leica CL and Sony A6700 Cameras
Leica CL and Sony A6700 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 CL
or the
Sony A6700 ,
including hyperfocal distance.
