Hey guys,


I need a little help making a decision on what lens to get next. I have a Canon 40d. My current lenses are a Tamron 17-50 f/2.8 and Canon 200mm f/2.8. I have about $600 to spend on a lens right now. The Tamron focuses a little slow in low light for my liking, and I would like the versatility of a telephoto zoom instead of the prime. Would you recommend selling the Tamron and getting the Canon 17-55 f/2.8 IS, or selling the Canon 200mm f/2.8 and getting the Canon 70-200 f/2.8 (Non IS). Another option is to sell both lenses right now and get the Canon 17-55 f/2.8 and the Canon 70-200 f/4. I will be using the telephoto mainly for sports and wildlife. My birthday is coming up on June 1st and I will be getting approximately another $600 to play around with then, but I would like to use that for a macro lens. Thanks for the help.
