Sony A6100 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 A200 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Sony A6100's sensor provides 14MP more than Sony A200'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 A6100 and A200 sensor size comparison.
Sensor Size and Resolution Comparison image of Sony A6100 and Sony A200 Cameras
Sony A6100 and Sony A200 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 A6100
or the
Sony A200 ,
including hyperfocal distance.
