First up is the Canon 70-200mm f/4 L non-is, the workhorse of most pro photographers, although I have a f/2.8 is so it is only used when weight is an issue. I'm looking for $550 shipped on this puppy.
Then I have the Tamron 17-50mm f/2.8 IS Canon mount which is super nice for a walk around lens and has a great f/stop for low light situations. Looking for about $500 for this one, MSRP $650 from any store.
Then I have a Canon 28-135mm f/3.5-5.8 IS which has a wide variety of lengths for multipurpose and walking around. Offer up on this one. Sorry for the terrible picture of this one, it was a last minute decision and too lazy to take good shots.
Thanks for looking. Feel free to pm me if you would like further information.
