don't you have one of the Chinese adapters? I could swear you had posted about it one or twice. If yes, here are a couple of shots with the vivitar converter. They were taken when the 90mm lens would focus up to 30 feet or so. now it will focus to 100 yards. Regardless if you have an adapter or not, what is your opinion? Fyi I had issues taking sample pictures due to motion blur (using an ist-ds so no SR and hand held lens to the camera in lower light).
I'll set up for test shots when I get a mount attached (waiting on another m42-pk from ebay and maybe tools to drill and tap for screws).
