Good luck and if you have any problems, email me direct. My use of this procedure works like a champ. If it checks out, then take your jewelers screwdriver and lock the infinity stops in, on the bed rail. When you have the sharp GG image and the RF locked in at that distance, then take it outside and try the system at infinity. When the RF is locked in, you then take the front standard and pinch the locking stops to pull or push the lens in or out to sharp focus the lens using a good 6X magnifier and observing the ground glass. This is done at a distance of a measured, 15 feet. You focus on this target with the rangefinder, and once you have this sharp in the rangefinder, you lock the bed and rangefinder image in. Linhof supplies a film targer that you place on an interior window. This is because the backs of the V and Master came under more uniform factory controls for back tolerances, and permitted users to buy lenses and cams for the lens, and set up the infinity stops for themselves.after the purchase of the camera body. It lists the Super Technika V and Master as applicable. Good luck.ĭavid: I have the official Linhof brochure and test target to establish correct focus. The technika rangefinder is a great and useful tool. 90mm lens cams are in my experience fairly interchangable on tech IVs because the 90mm lens has much better DOF tolerances at wide apertures than longer lenses. You are much more likely to have errors from an incorrect cam, particularly with longer lenses. (One more tip is after you think you have it right, push the top rail back a fraction on the bottom rail and then make sure that didn't make the image sharper.) With a bit of tinkering using a loupe on the ground glass and focussing back and forth you will get it right.

It is not that difficult - just be sure to use a loupe.Ĭonsidering the fastest aperture you will shoot is probably f8 it won't show in the photos (even an aperture of 5.6 still allows DOF within a couple of mm of front standard movement). Keep adjusting the position of the front standard until the front rails until you don't need to focus anymore then move the stops to that point and rescrew. Just loosen the small screws on the infinity stops so they move in their tracks, then focus on something that is at infinity (really at infinity - horizon stuff).
