I haven't purchased any lenses yet, but so far it seems that the best place to find a good deal on a lens is through Amazon.com. They show you a few different online stores so you can pick the best price. Ebay is always overpriced for the NEW lenses and I've never tried looking in an actual Camera store. Where do you all buy your lenses from? Any of you buy from only 1 place and nowhere else? Reasons why?
