Hi, i recently (about a month) purchased a d50 and a 18-55 f3.5( i think)-5.6 kit lens. I just got tired of my point and shoot. and while i am really liking it alot i feel the need to add a telephoto lens to my collection for my upcoming trip to barbados. I just have a few questions: what focal range?( or prime) is the VR worth it? should i even be looking for a telephoto lens? thanks in advance and if there is an FAQ here then please point me to it because i could not find it.
