It's a great lens & it has an ED glass element(s). It's super sharp (wide open too), with good contrast and colour. It's fairly well-built, and the lens barrel is metal. Mine hasn't had any mechanical problems. Optical quality is much better than the SMC-A 70-210mm f4 (which I also own).
The down side it that the AF is not that fast (clunky), it's slow (f4-5.6), has a rotating front element, no IF, and the manual focusing ring is small. For the price ($200 or less used USD), it's the best zoom in this range for Pentax users, and given it's optical quality, you can forgive the negatives. For optical quality, your next choice (IMHO) would be the $$$ f2.8 models from Pentax, Tokina or Sigma.
