Pentax K1-II with Sigma DG HSM 50 1.4 and Sigma 70-200 HSM II

They freeze my K1-II.
Apparently it is a known issue, however, Sigma claimed they are not offering fix these lenses anymore.
Do anyone have recommendation of a place/person can do the service on them? Very appreciated!

I seem to recall there were two issues:

1.Some lenses scratched the body.

2. The camera would be confused when the crop mode was set to auto. Setting it to FF or APSC solved the issue.

Perhaps someone who has these lenses can advise.

For repair on a sigma lens, I have used Midwest Camera Repair, Inc - Pro Service. They are an "authorized" service. Of course, they expect to get paid, but I was very happy with what they did as they cleaned the 17-50 as well as repaired it. I bought it used but it was like new after service. I expect they can advise you on your issues.

The only problem I have on my Sigma 50/1.4 HSM is the crop issue mentioned above. But it don't bother me much.

It literally freezes my camera. Nothing I can do. No buttons work with either lenses. Tried set to FF, didn't work. Tried contacting Sigma , basically no repair. Tried Midwest, they said they don't do that. Like hopeless.
