I was considering the 16-85, and it is a great lens far surpassing the 18-55 and 18-105. Ultimately ended up with the Tamron 17-50 f2.8 (non-VR) for totally different reasons, otherwise would have been the 16-85.
How does the 16-85 do on the short end? As I tested it, nothing to complain about unless you are being very critical. Yes, 16 does introduce more distortion, but that is almost normal for any zoom lens as they trail off at both ends. Given a choice, the Sigma 10-20 @ 16 may be the the one to select for the photo, but, if unable to change lens, the 16-85 @ 16 is perfectly acceptable.
