Sony A6300 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features BIONZ X 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 A6300 and A6700 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A6300 and Sony A6700 Cameras
Sony A6300 and Sony A6700 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 A6300 has 8% larger pixel area compared to Sony A6700, 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 A6300
or the
Sony A6700 ,
including hyperfocal distance.
