The f4-5.6 for $357 is the power zoom lens. It is very well made and reported by others on this list as very sharp. The f4-5.6 for $189 is a Tamron barrel with Pentax glass. Sharp and well built for the price, but not quite as good as the PZ. The f3.2-4.5 is the newest design from Pentax. Unfortunately I have not had my hands on this one yet. I hope I have helped.

I was just browsing B&H's site pricing the popular Pentax 28-105 zoom. But wait, there's three of them: Price: $ 199.95 Zoom Wide Angle SMCP-FA 28-105mm f/3.2-4.5 AL IF Autofocus Lens Price: $ 357.00 Zoom Wide Angle SMCP-FA 28-105mm f/4-5.6 Autofocus Lens Price: $ 189.95 Silver Zoom Wide Angle-Telephoto SMCP-FA 28-105mm f/4-5.6 IF Autofocus What is the difference in quality between these three? I'm confuscated now.... rg
