...my newly remounted Sigma 70-200 f2.8 just freezes the camera.
You should have asked for a firmware update for your 70-200.

There are certainly copies that work just fine with a K-1.

Hopefully your model can be updated. If you provide Sigma with the serial number of your lens, they should be able to tell you whether it can be updated.

I think that when I've sent lenses to Sigma's US headquarters in the past for service, they check and update firmware as a matter of routine.

Which version - OS, or HSM II?

My HSM II worked fine before it went to CRK for the fix, and worked fine on the K-1 when it came back.

It is the HSM II version of the 70-200. Still awaiting a response.

I know that here in Norway it is the local repairshop that fix theese issues. So should not take to long. Find a local Pentax/Sigma repairshop and ask them.

On the Sigma USA lens modification process, last fall we sent our Siggy 150-500 v2 lens back to Long Island, SIGMA did the upgrade (looks like they replaced the whole mount) and calibrated the lens. Before it worked it had a +3 back-focus on our K-3s, now it's dead zero, also focusing and zoom rings are smoother.... Nice job and results.

Hello. In Portugal, I 've asked to a sigma seller in november and send the serial number of a 35 art f1.4 and a 70-200 f2.8. They asked to the sigma japan that send new baionet to change. It take 2 months. Then once the seller is 300km from me i send the lens to them and in a week they have made the repair.
