Here is the short version: Bought a super16 converted Bolex EBM from Mr.Bolex. I get the camera, do a film test and the focus in the captured image is a few feet behind the subject in focus in the viewfinder. Mr.Bolex tells me to adjust the small set screw to the camera-left of the beamsplitter prism. As I understand it that screw only swings the beamsplitter prism on its hinges and does not adjust the focus of the prism/ground glass.
So I guess I need to move the prism either backward/forward in relation to the gate or as you said vertically.
Could I adjust the prism vertically by just loosening the mount screws?
One option is too do this myself with the help of a prismatic focuser. The other alternativ is sending the camera back to the seller.
What are your thoughts Simon?
