Fujifilm X half has a
18.0MP 1″ (11.7 x 8.8 mm ) sized BSI-CMOS sensor . On the other hand, Sony RX100 III has a
20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features Bionz X processor.
Below you can see the X half and RX100 III sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm X half and Sony RX100 III Cameras
As seen above, Sony RX100 III has a 1.1x Larger sensor area than Fujifilm X half. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Fujifilm X half
or the
Sony RX100 III ,
including hyperfocal distance.
