I have not done an extensive amount of shooting with the DA50-200 as yet, just my first set of walking around shots. I did several shots with the Pentax Rear Converter 2x-S fitted during that walk around. Reviewing those, wide open at longer focal lengths I saw a small and easily correctable amount of CA when fitted with the teleconverter, which just about disappeared 1-2 stops down where I'd normally use the lens. Without the teleconverter, I see no CA of any significance. Yes, I'm quite taken with the DA50-200. I only rarely use field of view much narrower than what the DA70 offers but I like to have the option. I've owned many longer lenses in the past and always found that they were either poor performers (I couldn't afford the premium glass) or so large and heavy I never used them. The 50-200 performs very well and is compact/light such that it is worth having, especially at the price. I feel it easily performs on par with any of the modestly priced zooms in this general focal length range that I've tried.
