Hello guys and gals...I was wondering if you could give me some advice as to what lens to use with a Pentax *ist DL. Im either taking pics of big nature scenes or pictures of individual flowers or closeup shots of my dogs/daughter etc... Is there a lens that would give me the ability to take pics of full scenes and do closeup shots as well? Or would that require two different lenses? Thanks for the help and please excuse my elementary questions! Im ust upgrading from point and shoot cameras! THANKS!
