@chaxdaman : of its not safe, but if u need to open a lens material needs to be made available like thinkpads [
ThinkWiki ] thats what makes thinkpad really great. To me if a company makes available their service manual then that company has nothing to hide, ofcourse they would make a lot more money as unnecessary opening would result in more servicing.

I'm now looking for a cheap Pentax DSLR to convert my 16-50 to screwdrive.
Your conversion might have failed as the little contact strip is broken between the lens circuit and the focusing circuit.
