Sigma APO 150-500mm F5-6.3 DG OS HSM-Sony Mount 73A-205 Norman Camera Questions & Answers
The lens does not focus manually or automatically.
Hi.
I have a lot of experiencie repairing Sigma lens.
In this zoom 150-500, the problem is located at the focus mechanism. This is a rear-focus lens so the focus mechanism is close to the bayonet.
It is not very hard to repair, but is better if you send to a Sigma Service Station.
Normally the mechanism is stuck due to a fall or strong punch.

Where can I find out how to take apart a Sigma 150-600mm contemporary lens?
Taking it apart is not the problem - re-assembling it will be. Unless you have access to an optical laboratory, where laser instruments can measure the exact tolerances required, don't even think about it. You will be left with a pile of optical components, and a far higher repair bill than if you had just let the experts sort out the problem in the first place.
My sigma 50-500 lens is lock in 500mm position
I believe on some Sigma lenses there is a switch to lock it in a 'Macro' position, usually at the long end of the zoom range. If this applies to your lens, it may be worth checking that this has not been accidentally set. There may also be some information in the manual whichcame with the lens.
