I'm with Rice on this. He's not saying the color is bad, just that it doesn't look like Pentax. It looks much like my Nikon. Half the reason I switched from Nikon to Pentax was that the Pentax color rendering, particularly of greens, was more to my taste. The only photo in the reviews that wouldn't stand out just a bit if I was going through them is the one with the wagon wheel in the first review -that look like it could have come straight out of my 50-135 (though maybe the wood is a touch warmer than the 50-135 would render it). In the rest, the greens lean towards yellow more than the lean towards blue as they do with my pentax lenses.
