How can I focus a 75 mm lens for vertical shots, dropping the bed out of view, on the Tech V? The standard wants to sit half on the geared [bed mounted] track, and half on the housing mounted storage track for infinity focus. Problem is [for those of you without Linhofs] dropping the bed places its track at a 15 or so degree angle to the housing track--the front standard must choose [I must choose really] the forward or rearward track. The rear / housing track is ungeared, so fine focussing would be problematic. Anyone know that a half inch Bromwell [or other] recessed board will sit the standard on the geared track?
