How to fix my Sigma 17-70 OS for the 4rth time, it keeps on shaking from the inside?

Its been sent to the service center for 3 times just for the same problem, I'm wondering if anyone out there had the same problem as I did. And if anyone out there has a solution or forums, website that can be refer please do S. O.S in this one. Love the lens hate the shake of the OS even if its turned off and it drains my Nikon d7000 battery quicker.

I'd say after 3 times perhaps you should get your money back from Nikon or a new lens… What do you think?

You know, many generic lenses just do not work as well and the lenses made for cameras by the camera maker. If Sigma can't repair it, what makes you think you can?

After 3 times, I suggest you get your money back and buy a different brand, like maybe a Nikkor 18-70 mm. It is only a third stop slower than the Sigma and in the world of digital camera and your fine D7000 camera, you will never see the difference when upping your ISO even a full stop to compensate
