Sorry if this shows up twice, but I think I sent it from the wrong address, before...
I've got a couple of SM lenses with the little push rod arrangement for stopping the lens down. Is there a simple solution to keeping it pushed in when using the lens with a screw to K mount adapter?
Use a modified M42/K adapter: http://www.jr-worldwi.de/photo/index.html?M42_auto_adapter_Pentax_PK.html
