One advantage the Sony Cyber Shot DSC-W100 has over the DSC-W70 is a sensor that's capable of shooting at ISO 80. Photos shot at this sensitivity level--and to a certain extent, at ISO 100--are relatively sharp with little noise and few processing artifacts. Beyond that, the aggressive noise-suppression algorithms kick in, blurring and smearing details. Photos print reasonably well to as large as 8x10, but they look a little soft and foggy. In addition to some distortion in the bottom corners at its wide angle, the lens also produces some cyan and magenta fringing on the sides, as well as purple fringing on high-contrast edges.

Review

Despite being a solid shooter in good light, as well as performing strongly on movie capture, the Sony Cyber Shot DSC-W100 can't match the value of less expensive, lower-resolution competitors such as its brother, the DSC-W50, nor can its photos match those of the low-noise Fujifilm FinePix F30 or the Canon PowerShot SD600.
