Check out an examination of photo quality from the budget-friendly Sony Cyber-shot DSC-S2100, the company's entry-level point-and-shoot powered by AA batteries.
Photo quality is good for an entry-level camera. Subjects are soft and smeary with little fine detail even at its lowest ISOs, and it only gets worse as you go to higher sensitivities. But, because of consistent color performance up to ISO 800, you can get decent shots in dim light. You won't want to blow them up, crop them heavily, or print them much larger than 4x6 inches, but considering the cost of the camera, they aren't bad.
The lens is noticeably low quality. There is noticeable barrel distortion at the lens' widest position (top) and minor pincushioning with the lens extended (bottom). Center sharpness is OK, but it drops off dramatically to the sides and in the corners, making things look very soft. If you buy this camera, make sure you frame up your subjects in the center of your shots.
