i recently bought a 28-200mm. the main reason i bought this is becos i wanted a power zoom that cover wide and tele as well. of cos, the best might be to buy the 18-200mm VR nikkor, but then, i no money so i settled for a much much much cheaper lens instead.
i wanted such a lens becos i didnt want to lose shots while changing lens. depending on if u really can work with jus 1 lens attached to ur camera at all time. i cant, cos i like to take wide sometimes, and sometimes, i will up the focal length to get the shallow depth of view effect. hence, change lens again and again was a hassle to me. also cost me some shots some times.
i havent perfect my 2 sec lens changing drill. haa haa
