Sep 19, 2012 11:19 | #2 Correction... there is still a slight high pitch sound if you put your ear on the lens just like there use to be but it's intermittent and it's simply not working... this blows A7rIII | A7III | 12-24 F4 | 16-35 GM | 28-75 2.8 | 100-400 GM | 12mm 2.8 Fisheye | 35mm 2.8 | 85mm 1.8 | 35A | 85A | 200mm L F2 IS | MC-11

SMP_Homer Cream of the Crop  More info | Sep 19, 2012 11:28 | #4 try pics with and without OS turned on... make sure you shoot at 200mm and somewhere around 1/60 to 1/100 to see how its doing EOS R6’ / 1D X / 1D IV (and the wife has a T4i)

Sep 19, 2012 11:32 | #5 The OS on the Sigma 70-200 is fairly well audible, so if there is no initial click, ending click, etc, then it's broken. Also, considering that it's at least a 3-stop OS system, it's very easy to tell at 200mm whether the OS is working or not.

Guys you don't get it... with the Sigma when the OS is on the viewfinder locks in and is rock solid steady but nothing. No audible clicking just a slight high pitch noise..

As for cost, the lens should have a 4 year warranty and it hasn't even been out that long, so you should be covered aside from shipping costs to Sigma. Ya sorry. It's official it's not working.

I guess you need to send it in for repair Have you sent yours off?

DreDaze happy with myself for not saying anything stupid  More info | Sep 19, 2012 12:16 | #14 i wouldn't send both your sigmas in with the same box...if your 70-200OS takes weeks to repair, there's no sense in being out the 30mm as well... Andre or Dre

As far as the warranty goes... I'm 2nd owner. I don't have the invoice when the guy purchased it. I do have a packing slip from amazon with the sales price on it. this was one of the $950 specials that happened last year. I hope that will count as an invoice. . It may. Do you still have contact info for the original owner? They may be willing to log into amazon and print a real invoice for you. Taylor
