Sony ZV-E10 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Bionz X processor. On the other hand, Fujifilm X-T30 III has a
26.0MP APS-C (23.5 x 15.6 mm ) sized X-Trans CMOS sensor and features X-Processor 4 processor.
One other difference between these two cameras that is worth mentioning is that Fujifilm X-T30 III's sensor doesn't have an anti-alias (Low-Pass) filter. 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 ZV-E10 and X-T30 III sensor size comparison.
Sensor Size and Resolution Comparison image of Sony ZV-E10 and Fujifilm X-T30 III Cameras
Sony ZV-E10 and Fujifilm X-T30 III 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. On the other hand, since Sony ZV-E10 has 8% larger pixel area compared to Fujifilm X-T30 III, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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
Sony ZV-E10
or the
Fujifilm X-T30 III ,
including hyperfocal distance.
