Here’s MacWorld Buying Advice on this Sony Alpha DSLR-A100 camera: “The Sony Alpha DSLR-A100K is a very good camera, albeit a little pricey. While it feels clunkier than its competitors, it delivers very good image quality and a full feature set, as well as some nice extras such as image stabilization. While Sony has released a good selection of lenses for the Alpha 100, its lens collection is fairly expensive when compared to the digital-specific lenses from Nikon, Canon, and Pentax. The Alpha 100 is a good competitor to the Canon Rebel XTi and the Nikon D80, but you should get your hands on all three to get a feel for their interfaces and grips before making a decision.”

Pros: Small size; full featured; very good image quality under most conditions; good lens selection; sensor-based stabilization.

Cons: Sensor-based stabilization is inferior to lens-based stabilization; lenses are expensive; autofocus mechanism is noisy; images look noisy from ISO 800-1600.
