Wow, I am really impressed with this lens! I am going to have to put it on my wish list. I was considering the Tamron 17-50 VC as a good candidate over the Canon 17-55 IS, but I may have just changed my mind

I had the Tamron 17-50 VC and was not impressed at all. I tried two copies, neither of them were sharp enough to cut the muster. It was replaced by this, and I am extremely happy with it. It's worth every penny more than the Tammy 17-50 VC.

Well, I'm glad I started researching Sigmas then!

Hi all,

Is this lens have a lots of QC problem? front or back focus issue? How frequent of lemon copy?

took the leap of faith and went with this one instead of the canon 17-55..
the $75 amazon gift certificate was plenty helpful. haha.
I'm looking forward to it. Lightrules' comment on where the canon is a 10, the sigma is an 8, made it happen.
I'm glad I've got the extra 300 bucks in my hand too.

There seem to be enough problems that I would suggest buying from somewhere with a decent return policy, but the sigma QC problems are overstated on the forums. I have a bunch of sigma lenses now and no problems with any of them, mine arrived perfect from the start. Some bad ones for sure, but not as many as you'd think from reading on here. Keep in mind that the people with a problem are much more likely to complain than those who are busy shooting with a lens that does what it's supposed to.

Here's a shot wide open, ISO 400, on a 7D. Focus was on the second "m" in "Mamiya". Click image for 100%. Definitely some CA on the high contrast edges, but surprisingly sharp wide open within the fairly shallow DOF this lens offers. Again, I am very happy I made the decision to go with this lens.

In low light condition and with the OS on, what is the max shutter speed can one push it to get a keeper? I know the question is subjective but I think you know what I mean...

I happy with what the Tamron 17-50mm non-VC can do and was thinking of saving up for the Canon to get IS but it is over 1K ouch . I think the Sigma is fitting well for my plan.

Sounds like quality + price is a better deal breaker than the Canon 17-55mm IS

Please post your best deal on this baby. Is your deal still available? TIA.

Go on eBay and search for it, find 47stphoto, and they have a best offer setup there. I offered 629 free shipping and they accepted. You should try lower.

I'm still getting used to the lens, but I'd say it's pretty solid still at 2 stops slower than when I have the OS off or when I was using the tamron (which I had before this). I have kinda shaky hands so for me I still don't go super slow, but 2 stops is fairly safe and that's usually all I need anyway. Many times that makes the difference between an ISO 800 keeper and an unusable ISO 3200 shot...

I've seen 4 stops quoted before and I wouldn't trust that, but I probably wouldn't trust it for the canon IS lenses either

just my 2 cents, I'd also be interested in hearing more opinions on this...

(sorry for contributing to all the chat here, I'll try to get some pics up soon to contribute and make up for it)

Here's a few shots I took messin' around tonight with high ISO, all shots taken @ f2.8.

I LOVE THIS LENS!!!!!! Stupid sharp. So incredibly glad I didn't spend the extra cash on the Canon

Just a couple SOOC snap shots I got last night.

Has anyone tried both the canon 17-55 and this sigma?
what I'm really worried about is the AF speed. I can live with sub-par sharpness etc, but I need AF speed for what I usually shoot. (kids, people.. etc)

I'm sure the canon is faster, but is it worth that $300 bucks?

It has a different feel than the 70-200 HSM II but it is fast. I got mine about three weeks ago and have been using it for basketball for baseline shots.

My photography skills are weak, but a work in progress.
Here are some from an air fest a couple of weeks ago.

Just got my 17-50 today, I am really looking forward to giving it a whirl tomorrow. Did some focus charts and it is spot on. Once question about it though, does everyone else's copy have the old sparkly EX finish? I thought it would have been the new matte finish like the Sigma 30 I also just bought.
