Did your 10 have a lense already? If you don't have to reset lense and gear distances, your better off. I've had some really good luck and some bad luck with it as well. Even after measuring really carefully I always test the settings by setting up a marker with writing on it, setting up the camera and shooting the marker at about five places around the center to see which point has the leaast amount of slur. I could go on about that a bit. It's a pain. Most of my cameras were "Bargains" and in need of it. Do you have a #6 cirkut outfit or #6 cirkut?
