Canon EF 70-300mm IS USM Lense Review | DSLRBlog:

Chris over at DSLRBlog just got himself a new lens - and he has a review of it!

I like the sound of the store he bought from as well - too often have I been made to feel like a criminal for actually wanting to trial a piece of kit (in the shop, of course) before getting out the credit card. A guaranteed way to annoy the vast majority of your customers who don't want to steal from you...
