Nikon D3300 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Expeed 4 processor. On the other hand, Sony A58 has a
20.0MP APS-C (23.2 x 15.4 m ) sized CMOS sensor .
Another difference between these two cameras is that Nikon D3300's sensor lacks 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 D3300 and A58 sensor size comparison.
Nikon D3300 and Sony A58 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.
