I've been considering this move as well, but...the Sigma lottery aside, i can't see it offering the sharpness, stellar focusing and awesome IQ..of either the 7-2 f/4 IS or the 7-2 f/2.8 II. OS should be equivalent, nice shallow DoF and extra stop, but bokeh and color worry me... besides possible focusing and QC issues. So.. do you end up with an overall upgrade/improvement or not?
I object to the term Sigma Lottery- as it is no more a lottery than it is when you go to a vending machine and pay for a coke. Yes, there may be a few bad apples in the mix, but I think that most people that buy a Sigma lens gets a decent lens. Like a vending machine, whomever brings it to your door (aka the vendor and or fedex guy) have just as much to do with how good of shape it is in when it gets to your door. So, when you stick in your dollar into a vending machine, press Coke, and get a dented can- do you blame Coke for that ? Your statement seems contradictory afterwards, much like a Canon fanboy.. "I've been considering...", apparently never owned it, and "it can't offer the sharpness, stellar focusing, awesome IQ,..." For most, the Sigma offers the IQ or nearly the same IQ, but at a fraction of the price. Now, as far as the rest, it assumes that the Canon is immune to AF issues, focusing issues, QC issues- but Sigma is full of them? Again, much more fanboy than anything.. What's the term- troll. How many threads are there on this board where a Canon lens user had to send the lens and or camera in for adjustment because of this or that? Get over it.
Rant finished. I have one. I am happy with it. OK, so I don't print poster sized images- so I don't know how it will fare.. but till then, it will suffice. I've won the "Sigma lottery" 4 times so far. Where's my prize ? Didn't buy the Canon- as $2500 is a pretty steep price to pay- at least for now. I don't have a Canon f/2.8 IS USM Mk II to try out- so I can't offer an opinion as to which is better. But I wasn't looking for a $2500 lens, and I didn't want it white either. I'll take one if someone is giving one away for free though. Preferably new. Can that be my prize ?
To answer the OP's question. The Sigma 70-200 EX DG HSM OS is what you are looking for. There is only one with OS in the model name. It's also rated the best of the Sigma 70-200's.. It's also the newest design.
