Sample variation or so it seems, though this case of the dueling reviews makes me think it's becoming extreme. In the good old days the Photozone tested lens wouldn't have gotten off the line let alone out of the factory. (God I feel old typing that). The fact that Pentax Germany doesn't seem to find anything wrong with the lens is just bizarre. Even the much maligned 28-200, which is pretty much the equivalent lens from those old days preforms better.
There have been a lot of reports on ForumsNeurotica of people not being able to get sharp pictures off of the K5 (which it appears PhotoZone is using as a test camera). The K5 is VERY demanding of focusing, and it's entirely possible that Photozone was unable to (or didn't) optimize their camera and focusing for the lens. Everything I've read about the lens so far is that it is quite qood to excellent, so I would take the Photozone test as flawed, since so far they are the only people to pan the lens.
