Evening all, I've really been enjoying using my Canon Powershot G7 the last few months but am thinking now about investing in a lens.....but don't know much about these things. Would a telephoto lens be the best option to start out with (ie I'm one of those ambitious amateurs)? If yes, can you recommend one? I haven't a clue how much these lenses cost, my budget would be up to $200. Would really appreciate any advice, thanks.
