Camera Sharpness Comparison

Sony A55 vs. Sony A99

Sharpness at 12mm.
APS-C sensor vs. Full Frame Sensor with same lens.
 
Comparison by Sinan Ozturk   
This comparison is to demonstrate how much details you can get with a Full Frame camera (Sony A99) in comparison to a APS-C sensor camera (Sony A55).

In both cameras same lens is used (Sigma 12-24) and 3 photos with apertures F5.6, F8 and F11 are taken on a tripod under same conditions and camera settings.

Their exposure compasation was same (+/-0) and the reason Sony A99's photos are darker is due to Sony A55's general tendency overexpose. I didn't compansate for that during the shots.
