Sony A55 vs. Sony A99 Sharpness Comparison (at 12mm.)

Comparison # 2883
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. [Review by Sinan Ozturk]
