I've come to understand that people will see what they want to see. Those that wanted something faster, something smaller, something wider, something longer, will not be happy no matter how good the lens is and will focus on anything negative. As with any human manufactured, designed device there will be sample variation. Whether that was an issue with Adam's review I don't know. For those who are interested and want to consider another viewpoint that this zoom should be considered if you like the focal length range. This tester generated imatest data for the
DA21,
DA35 ltd,
DA40, and the
DA20-40 all on the same K-3 camera. If compare the data from each review you have another piece of information to base a decision as to whether the lens should be able to produce nice sharp images across the focal range. As having come from all of the compared DA primes, I can offer my unscientific assertion that yes it equals or betters the DA primes.

Measurements don't matter to the degree that I don't normally take pictures of line tests. At the end of the day, I buy and hold onto lenses that do what I need them to do. Not because they scored high on any specific test. It just so happens I do value sharpness, WR, versatility all in a compact package so the 20-40 will stay in my bag and the DA21, and DA40 are gone....and I'm wrestling with selling the DA35 ltd. And by the way it does render an image beautifully...at least to my eye.
YMMV.
