I was going back and forth between this and the 200mm f/2.8 II USM... Yesterday, I decided to take the plunge and order one from Amazon. It's currently at $579, shipping from Amazon, with FREE ONE-DAY SHIPPING. Less than 24 hours from when I ordered it, it arrived at my work, for only $579. Thought I'd pass this along to anyone who's on the fence. Hopefully I'll have some nice images to post here from my upcoming shoot this weekend.
I ordered through Adorama at the same price but shipping 3 days was $6. Looks like we ordered too soon because now Amazon has it for $559 with 2% back
regardless I think we both got it for a good deal but this one just happens to be a little better: http://www.amazon.com …e=UTF8&smid=ATVPDKIKX0DER
