But U did some modifying on it (longer zoomstick, b+w filter etc.) I als deatached the automatic diaphragm system to get a more "pure" and manual feeling. But now when I look into the viewfinder the picture is not very sharp and when I try to focus with the focus ring nothing changes --- still the same unsharp image. Also when I look into the lens an move the focus ring nothing seems to move. Its kinda sad because the Schneider Optivaron 1.8/ 6-66mm
