I have searched the forums extensively to find some definitive information on this issue, and failing that, am posting here...
To all 10D and 20D owners who own Sigma lenses: Have you experienced any problems, as far as compatiblity with Canon/Sigma??
I plan to purchase the Sigma 70-200 f/2.8 EX APO IF HSM this weekend, and my local camera shop is trying to steer me away from it, saying that "there are sometimes problems with compatibility with Canon Digital SLRs". Obviously, they are recommending Canon glass, which I cannot well afford right now. (But...they are also "pushing" some Tamron lenses, though nothing in this focal range.)
I have read extensively about this lens, and have found no articles, reviews, or forum posts talking about compatibility issues, and in fact, have found that, overall it appears to be a terrific lens for the money. If any of you are using this lens, I would appreciate it if you would "chime in" with your experience. |

I have the Sigma 100-300, 15-30 and have owned the 70-300.
Absolutely no problems whatsoever with any of them, and the quality on the EX range is superb.
As long as it's a recently produced lens (last few years) I don't see there being an issue. The problems I've heard about have all been with old lenses which needed to be rechipped to make them compatible.

Sigma's 70-200 EX is a gem. Even if there is an incopatibility issue (there used to be some quirks with Nikon's F mount with earlier models of the lens, I've never heard anything for Canon), Sigma will re-chip it for you for free. I don't know how things are in your country, but in Canada, all the EX lenses have 7 year warranty and 48 hour turnaround - the best guarantee in the biz.
Go buy this lens, you won't regret it.

Ihall,
I just a few days ago got my Sigma 70-200mm f2.8 that you are considering. I haven't had but a couple shooting opportunities with it so far, but to this point I am quite pleased with it. Construction seems very solid on it too. I can't speak to compatability with the 10D and 20D, but it is working fine on my 300D. Hope this helps.
Doug

| Some of the older sigma lenses had probs with newer EOS AF systems. Sigma would "re-chip" them for free to fix the problem. Some of the older lenses are no longer supported this way. Any of the current Sigma lenses (i.e. the 70-200 f2.8) should be just fine. |

I think both the 10D and that lens have been out long enough that any problems would have surfaced by now. I'd press the local shop to be more specific about the issues they raise. Ask them if they would accept a return if you had incompatibility problems; or, better yet, take your 10D in to the shop and give the lens a test drive.
Just out of curiosity- which Tamron lenses are they pushing?

| I have a Sigma and a Tamron lens in my collection and have not had any problems with them on either my 10D or my 20D. So set your mind at ease :) |

Thanks SO MUCH for all the replies. I AM definitely buying this lens this weekend, along with the 580ex flash, (and another CF Ultra card).
@coolhar: They are "pushing" the Tamron 3.5 19-35, Tamron 3.5 24-135, and especially Tamron 2.8 28-75 XR Di LD (IF)-(which I am considering.)
I think they like the Tamron because they carry them in the store, and they don't carry Sigma. They've never tried to "make" me buy anything in particular, but then again, I've always gone Canon; (but they have mentioned several of the Tamrons before.) |

OK, I don't have a 10D or a 20D, I have the little brother 300D, but I do have a Sigma lens and there was some compatibility problems with it. Let me explain....
The reason I bought the 300D body was because of the lenses I had from my now old EOS non digital SLR. The lenses I was told would work fine with the 300D.
Not quite, my other two lenses, both Canon glasses worked perfectly, but the Sigma auto focus 18-35 didn't. Well it did at first but not for long. The fault seemed to develop very quickly from not working sometimes, to not working at all in the space of a week. I too searched the forums and found lots of references to the same problem. The camera failed to control aperture when the shutter was pressed and the display just showed Error 99, the book say that's an unknown error, very helpful Canon!
Anyway somewhere on the forums somebody said that this was a known problem and that provided you have the original receipt as proof of purchase, Sigma would "fix" the lens free of charge. After confirming this with Sigma, (Sigma UK in my case), I sent off the lens and waited. It took about a month to get it back but its worked without a problem from then on.
I suspect that this is a problem only with older lenses, which were never designed to work with a digital camera, that's my theory but it may be wrong. Are there any major differences in the lens connections of digital and non-digital SLR's?
Hope that helps.
