Panasonic DMC-ZS20 Digital Camera Review$349.99
The Panasonic DMC-ZS20 performed pretty well in our sharpness tests, lagging just behind the better superzooms on the market. The camera had maximum sharpness of over 2000 lw/ph around the center of the lens, though this fell off dramatically near the edge to around 600 lw/ph. That's still decent performance, and it's what we expect from a compact camera with such an extensive zoom range. The camera does apply a pretty standard amount of sharpening, resulting in many edges having a white halo on one side and a dark line on the other, upping contrast. This works well for broad lines, but it does tend to hinder image quality of more complex shapes, like tree branches intersecting. More on how we test sharpness.
At 1/30th of a second the ZS20 did not return particularly sharp images with a standard, repeatable low shake applied, typical of holding a camera hand-held. The stabilization system did improve sharpness significantly (by around 50%), but it was mostly the result of improving on an already poor result.
