Below you can see the X-T10 and A290 sensor size comparison.
Sensor Size and Resolution Comparison image of Fujifilm X-T10 and Sony A290 Cameras
Fujifilm X-T10 and Sony A290 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
Fujifilm X-T10
or the
Sony A290 ,
including hyperfocal distance.
