There is nothing awkward about this lens. I acquired it after having gone thru 2 copies of 24-105. I think it is a superb lens that allows you to get wide-angle shots and macro shots with one lens. Occasionally I miss the reach of the 24-105 but I have other lenses to cover the ground.
I also think the purported weakness at 50mm is way overblown. I'm aware of the tests, but if you look closely, stopped down, at 50mm it is still quite good. In any case I shoot at whatever focal length I want and never worry about its "weakness".
