Hey, it wasn't entirely altruistic; I was interested in seeing what this combination could do myself! Even though I own both items (the Vivitar S1 70-210 and the Pentax 1.7x AF TC) I'd never thought how useful they could be together. I found the results pretty exciting. Consider an ist-D or ist-Ds along with this teleconverter and lens and you have a pretty potent package in a very portable size/weight. >I'm also impressed by the quality of this rather cheap lens combo.

Keep in mind that this was shot at f/4.5, which is only half a stop from wide open at the focal length I was using (210mm). I wouldn't be surprised if it looked much better stopped down a bit :) -- Mark Roberts Photography and writing www.robertstech.com
