I hate to do this, but I bought a Pentacon 6 to PL adapter from Sergey Kravchenco at the beginning of July and have yet to receive it. I have sent numerous emails to him and have not gotten a response. Has anyone here bought anything from him in the past? Did you receive it? I realize that it takes a while to get here from Russia but I've purchased other things from Russia and Eastern Europe and its arrived in less than two weeks. Any thoughts?
