A review of the Konica Minolta DiMAGE Z20 digital camera has been posted at imaging resource.

Here is the abbreviated conclusion of the review:
“Delivering good color, sharp pictures, fast shutter response, and excellent battery life in an affordable package, the Konica Minolta DiMAGE Z20 offers excellent value for the money in a long-zoom digital camera.
Its range of exposure control from fully automatic to fully manual […] make it a good choice […] for people wanting a camera that they can “grow into” as their skills mature.
All in all, a nice little camera, and an easy choice as a Dave’s Pick.”
