DIY fix stuck zoom of Sigma 17-50 F2.8 EX
6 months ago

My Sigma Lens's zoom was stuck at 17mm during a trip. I actually don't know how it happended. It just couldn't zoom in the morning of the second day. (of course I know it's not the problem of the zoom locker)
The Sigma service said it would cost me about 150 euros, I would expect more if take the postage cost into account. So I decided to fix it myself.

Finally I did it. The zoom ring works again, AF is accurate withou back/front focus, every thing seems OK, execpt the VR can't be truned off! Actually I don't know if it's my fault, because I never turned OS off before, and I also notice there are some reports about always-ON OS in sigma lens and Nikon camera.

I will post my DIY repair procedure slowly, in case it could be helpful to someone.
