Re: Pentax 17-70 (VS 16-45)

Greetings! Well, I have the Pentax 16-45 (among other superb Pentax optics), and am frankly torn between keeping it or selling it for the Pentax 17-70, just for the longer reach. My BIG concern is Sharpness. I am pleased with the sharpness of my 16-45 on my K-5, and obviously want equal or better sharpness from the 17-70, but I've read many conflicting reports on this issue. Indeed, the Pentax forums rate the 16-45 a bit higher on sharpness than the 17-70, which I assume is related the the single ED element in the 16-45 that is not in the 17-70. Please correct me if I'm wrong. Ideally, I'm looking at selling the 16-45 and a beautiful Pentax DA*55 f/1.4 to finance a Sigma 8-16 and the Pentax 17-70 for an upcoming trip to California. (I want to travel as "light" as possible.) Thanks all, for your lens expertise!
