Pentax 200mm SDM to Screw mount conversion help

Hi there, I am new to the forum and need help! My Pentax 200mm 2.8 lens stopped working. I believe it is the SDM failure. I have been researching on the web for how to convert from SDM to Screwmount which I would like to do. I have found several sites that explain how to do the conversion. The only problem is that the main computer program needed, PKTether, no longer is available. Some say PK Triggercord has replaced it but I have been to that website and not sure how to use. Is there anyone out there in the Pentax world that does these conversions for a fee if I send them my lens? Or is anyone willing to write a new script that uses PK Triggercord? I have this great lens but it is useless in the condition it is in. I do not want to pay 320 dollars to replace the SDM. Would much rather convert it to screw drive. Thanks for any help.

I meant to add that I have a Pentax K5 DSLR.

We do have a forum member @UncleVanya who performs the conversion service for a nominal fee. SDM to Screwdrive Conversions - PentaxForums.com

He's a longtime member here with a good reputation and I would not hesitate in sending him a lens for conversion.

Peter. Send me a private message. I'm happy to help. If you want me to perform the conversion I can do it I've done a lot of conversions including the da* 200.

Welcome!

Good luck with the screwdrive conversion - its certainly be done successfully many times. Also for what its worth, its not a totally useless lens in the meantime as it should be pretty good lens to manual focus and not so hard to do.
