I have a Pentax *ist - I want to supplement the kit 18-55 lens with\na longer zoom. I'm considering the DA-50-200/4-5.6 by Pentax.\nMy needs are fairly moderate - mostly snapshots. Is there any\nother consumer zooms I should consider? Other manufacturers?\nMy budget is quite modest - so I cannot go after the really good\nglass. Any help would be greatly appreciated.\n\nTIA,\nPinaki.
