Nikon D5200 has a
24.0MP APS-C (23.5 x 15.6 mm ) sized CMOS sensor and features Expeed 3 processor. On the other hand, Sony A300 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Nikon D5200's sensor provides 14MP more than Sony A300's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the D5200 and A300 sensor size comparison.
Nikon D5200 and Sony A300 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.
