This idea is killing me....i had several lenses from canon and i never needed to send for calibration together with my camera. Is it not part of the deal that when you pay a thousand dollars you get somethign that is working right away?
I really do not get it.....strange. I purhasex my 70-200 and i never had to do anything, it is just phenomenal right away.
The same is with my Sigma 50.
If it's bad, you send it in to Sigma. It takes two weeks.
It IS rare that you have to send it in twice. I've not heard of that much. Sigma has QC issues on the 50 most. The 85 hasn't been around long enough to get much more than a few anecdotal bits of evidence. The only one that sticks out in my mind was someone who bought one that wouldn't focus properly at all - clearly a dud. I think that on the forums people **** about lenses way more than they sing their praises.
Sigma lenses are as good as and in some cases, better than their Canon counterparts. Don't hesitate to buy. If it's front or backfocusing, send it in. It's simple.
Don't read too much into peoples anti-Sigma tirades. If it were up to me, I'd kick people off the forum for it. It spreads bad rumors. There should be a sticky. If you get a bad lens, send it in. Simple.
