Was wavering between the Canon 15-85 or the Sigma I choose the Sigma for the 2.8. UPS just delivered it I was excited slapped it on my 7D the focus will not lock. It just sits there cycling back and forth, turned OS off no difference. Made some changes on my camera didn't help. I even went as far as cleaning contacts no good. Now I have to wait until tomorrow to talked with the place I bought it from who is on the east side. I hope they will do something about it as I bought it on Fleabag, but I got it from 47st which I have used many times in the past.

Mike

That's too bad. I loved mine to death. Hopefully you can get a good copy. It's an awesome lens when it works right!

I have owned it in the past so I know what it can do but I have never had a lens that does this :cry:

I will be calling them in the morning I really want to send it back. I am wondering if I got a return lens? mainly because the OS was in off and it was on M. Any new lens I have ever bought the IS or OS was always on and always in auto focus

At what focus distance did it do this? I had a 17-50 and after about a year anything below about 6 feet would do as you describe. Anything far away was fine. I sent it to Sigma and the replaced/repaired the GMR sensor and it was fine afterwards.

The shipping box did had a small dent on it but saw no damage to the inside. But a good drop could have done something maybe.

Called the store this am and they were awesome I can either have a full refund or they will replace it. I told them a refund because I was thinking I would pick up a used 15-85 IS. But I am having seconds thoughts about that and tempted to call them again tomorrow for a replacement instead. They are also paying for the shipping

Of all the companies that manage to stay in business despite themselves, they just don't get what quality control is all about.:rolleyes:

My sister, the professional baker and cake decorator once told me that my camera takes great pics. My reply was that I thought her oven baked great cakes.:lol:

The 15-85mm is nice (I have it) but if it's f2.8 you want, it's not going to help you.

People love to complain about Sigma but they do make nice lenses at better price. The 17-50 OS work for a lot of people. If you want to do low light, get the Sigma. If you want more range, get the 15-85mm. Simple as that.


Canon 6D | S35mm f1.4 | 135mm f2 The rest: T3i, 20D, 15mm f2.8, 15-85mm, 24mm f2.8, 50mm f1.8, 85mm f1.8, 90mm f2.8 macro, 55-250mm.
So long and thanks for all the fish

Yes it has worked for a ton of people some say it's very close to the Canon 17-55 in IQ
