Sony A3000 has a
20.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features BIONZ processor. On the other hand, Sony NEX-5R has a
16.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the A3000 and NEX-5R sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A3000 and Sony NEX-5R Cameras
Sony A3000 and Sony NEX-5R 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
Sony A3000
or the
Sony NEX-5R ,
including hyperfocal distance.
