I am having film registration problems with a Linhof Technikardan 45S that I suspect will be widely shared. Calculations based on careful test shots, as well as measurements with a homemade rig, concur in the conclusion that sheet film in Fidelity holders comes to sit about 0.5 mm behind the plane of the groundglass. The discrepancy is too large to be chalked up to measurement error. The camera back was inspected by HP in NJ and Linhof in Munich and found to meet their specifications. So I suspect there is a mismatch between Linhof specifications and Fidelity dimensions. Btw, no such discrepancy exists in my Linhof Kardan GT 810. Any suggestions as how to get this fixed?
