To make a long story short, I have "about" $6000 to buy a 5dm3... Then I was going to get a 70-200 IS II.
After some research, I was thinking, considering my lens layout, getting a sigma 70-200 2.8 OS and a 24-70 2.8 Tammy with VC might be a better purchase. They almost add up to the same price...
I have the 17-40L and a 28-75 2.8 Tammy, which cover the range but no VC.
I guess the question isnt how good is the 70-200 IS II (had one, loved it, sold it, regret it). The question is..how much worse is the Sigma 70-200 2.8 OS. My style of shooting makes me have the 70-200 on almost half the time so its a big lens for me. Also, I will assume the 24-70 vc from Tammy is a big step up on their $500 28-75...

Even though I know the dfference would be very minimal to non pixel peepers. Then there is the weatherproofing...
