Do you have a ground glass calibrated to the camera's film plane?Actually, also that doesn't work in my case, since the film plane is different to the digital back adapter plane (I do have the newer digital back mount that is compatible to the digitally mounted lenses) :shocked:
Who made the plate adapter for your digital back? Can you focus via Live View?
Curious, as I can achieve focus with my digital backs (P45 and CFV50c) with all my 4x5 film cameras (Sinar Norma, Cambo Wide 650, Linhof 3000).
I can also use them with my ALPA cameras without having to use the calibration kit that came with the P45 years ago.
Also, does the helical for your lens allow proper focus on the ground glass?
Only asking because your digital back should be able to focus with your camera if you can focus the lens on the ground glass.
I found hyperfocal focusing can be off when using digital lenses and digital backs.
It is not like shooting with film in a lot of instances.
