Not quite sure which forum this should be in, but it is a bit arty so... I have recently retaken up photography, and have a Canon EOS 400D which is a pretty decent camera. I have 18-55mm and 55-200mm lenses. What I want to do though it try a bit of close up photography. I can get fairly close up with the 18-55mm but I want closer... Are there any experienced photographers who can advise me on the best lens to get that won't need a mortgage to buy?
