The 70-200 is a different class of lens. I've never had to repair mine but I have had to repair my Canon 15-85 so I guess that's a wash. lol
I did drop my 70-200 onto a hardwood floor and knock the OS out of whack. I sent it to Sigma to get an estimate and when I called 5 days later to see what it was going to cost, they said they fixed it under warranty and shipped it back. It showed up on my porch later that day so I'm a happy camper. :-)

I don't think it's soft at the long end. I think it's a tad soft at f2.8 compared to the Canon MkII but I'm OK with that. "Soft" is a relative term and if the Canon wasn't sharper I'd be really surprised given the 2x price tag. At 200mm I've noticed that the actual magnification is slightly smaller on the Sigma compared to the Canon. I can't say for sure how much but when you place an image side by side at 200mm you can see the difference. It isn't a lot but it is noticeable.

A independant magazine about canon cameras, stated that the Sigma 70-200mm OS, is around 180 - 186mm, and that the canon 70-200mm f2.8 is only a tad faster and slighty sharper, in the real world. And this lens is better value than it canon counterpart (Sigma $941 compared to canons $2225).

That is my experience from when I used to rent the Canon Mk II. The main thing I notice is the IS/OS on the Canon engages faster and is quieter, plus you have the focus limiter which is absent on the Sigma

You won't regret it. I sometimes feel like selling mine when it sits, but I take it out and those thoughts go away.

BARGAIN! I paid $1179 for mine but I bought it when it first came out. Even that was a deal because it was an xmas special. I've never bought from 42nd street, but if someone is selling for $969 then I wonder if you call Adorama if they will price match it. I can't imagine that one store is getting them cheaper than another. The benefit of Adorama is that they will take your Sigma lens and test it on your kind of body if you ask them to before shipping to make sure you don't have any focus issues.

That is a good price. I bought mine used for $950 from a friend on this forum.

Before you pull the trigger I would do more research on that company. What I have read doesn't correspond to the Google reviews they have.

Thans four your answer. No, all miss-focus. In a series of 5 images 1 or 2 are blurred. I am shure it is not the OS, it is workig fine even at 1/5 sec. Could you tell me more about the atmospheric distortion ? Camera is 5DII. Thanks!

I had sent it to callibration, with the 5DII body. Now it's sharp, MicroAF=0. I still have problems with the TC2x,, images are a little blurry, but probbably I have to learn how to use it. TC2x can be used with Sigma 70-200 wits image stabilisation ON, hand helded ?

Yes. But are you shooting with a Sigma TC or another brand? And are you shooting with fast enough shutter speeds? You'll need a shutter speed twice as fast as what you usually can get away with because of the 2x focal length. Test it in a tripod with the OS turned off to be sure.

I've had a lot of hit and miss with TCs in general.....more misses than hits really with a crop camera but since you have a full frame you should have better results than me. They do soften the image for sure. Even the best will soften it some. And they can be finicky. Many only work really well with the same brand lens. And that includes even the Canon versions. And as much as I love my Sigma lenses, their TCs aren't very good compared to the Canon (They are still better than the cheapies). I've been through several, always thinking that maybe I just had a bad one. Each time I was disappointed. Their current one is due for an update as well.

Unless you are just shooting at shutter speeds too slow, I suspect the problem is just a poor match between the lens and the TC or a higher expectation than what your TC can actually deliver.

Thank you Kfreels for your answer. The TC2X is Sigma, I have bought it with the lens. Probably I have higher expectations from it. I'll do more testing and I will come back here with some pictures.
