I've posted wide open shots from the 7D and the 17-55. If you feel the 17-50 is so much better post your shots and let the OP decide.

You've apparently not understood my posts (or didn't read very well what I've said). First, I frankly don't think your crops show anything meaningful. Your 7D and your 17-55. Hurray. It isn't any comparison to anything. Second, I never said the 17-50 was "so much better"; I said it's "better" concerning overall build, optics, and warranty. That doesn't mean the Canon sucks. It doesn't. It's actually quite stunning in some ways optically (I used 2 copies for 2 years). Third, me posting shots of my camera and my 17-50 post-processed doesn't prove anything. Just look at the lens archives for plenty shots by 17-50 users. I posted crops between the 17-55 and 17-50 under the same variables for the purpose of comparison. That is more useful for the OP than just showing pictures I've taken with it.

Don't be so defensive. I didn't make fun of your dog or anything like that :lol:

I don't have a dog. ;)

I don't know, my shots showed the the 17-55 wide open on a 18MP sensor. I think that is worthwhile information for the OP. I'd still like someone to post wide open shots from the 17-50 on a 7D to se if there is indeed a wide varience in copies since I only shot one copy and it was borrowed.

FWIW, I last cleared out and archived my LR DNGs in November, I'm not kidding, I have enough to keep track of with what I currently own.

JFC, the point is that the 17-50 and the 17-55 are apparently very arguably close. Some very learned folks prefer the SIgma and some the Canon. Doesn't that make it something of a slam dunk for the OP to choose the 17-50 + the UWA instead of just the 17-55?

I was a bit hesitant to trade my proven Tamron 17-50 non-VC for Sigma 17-50 OS because of all issues I kept reading about regarding "Sigma Lottery". However I never read anything about this particular lens. It appears Sigma issues are very model specific, e.g. 30/1.4. My 17-50 OS was great from day one (April of last year). I highly recommend it.

I had the Sigma 17-50. Loved it, but the outer regions were not as sharp as the center was. It did mess with my wedding shots from time to time (group shots). I also found AF, while good, was not quite 100% spot on.

I sold it and upgraded to the 17-55 (which I've owned before).

I've had both, used both, got paid for pics with both and found the Canon was a better overall lens than the Sigma (though not by a whole lot).

I finally found the review that pretty much matched my experience:

http://www.the-digital-picture.com …C-OS-HSM-Lens-Review.aspx (external link)

BTW, I'm not a fan of the Canon 10-22. I personally use the Tokina 12-24 f/4 because I don't need the extra 2mm on the wide end. I think the best WA lens that goes as wide as 10mm is the Sigma 10-20mm f/3.5. If you watch the Sigma outlet you may find that or the 17-50 but they seem to only have one copy of a lens at any given time and you have to jump on it.

Never had any trouble with my Sigma 10-20 or my 17-70 - or my 70-200. Just my 30mm f1.4 had issues and it had issues twice. I'm confident in their lenses. That's why I keep buying them.

I would say that this is the best conclusion tha one can draw: Why buy an expensive Canon when you can buy a Sigma that is very close to that Canon, plus an UWA?

B&H just made this an easy decision.

Price drop to $594 on the Sigma. Bought. Option A it is.

I am shipping my barely opened 30mm 1.4 to Sigma tomorrow for calibration - I wonder could I just drop ship the 17-50 and the 10-20 directly to them for calibration? Then they ship me my whole pile of gear and camera body back. That way I only have to do this once? All the Sigma horror stories make me anxious.

BTW for anyone who is wondering - I called Sigma and you can't do this. You have to first receive the lens, then if it stinks, you send it to them........crossing my fingers that I don't have to send them my camera body multiple times.

The 105mm OS macro also is $200 off. If that is anything like the old 105mm macro with OS added that's a great deal at $769.

I would have thought it was obvious... You can't expect them to calibrate a lens without you telling them what is wrong with it. That's like going to the doctor's or the pharmacy and asking for medicine without telling them what your symptoms are.

Understood, point taken. My only hope was I'm already at the pharmacy for something else (my T2i and 30mm has already been shipped to them for problems). May as well ask for a well check or extra antibiotics on something else while I'm at the pharmacy (17-50mm check on my body) so I don't have to make the drive back to the pharmacy........althou​gh I suppose a pharmacist wouldn't give me extra stuff unless I was sick.......uh-oh......my analogy is breaking down. Doh!
