Linhof super technika lenses adjustment instructionsAdiustment Instructions For lenses Ordered Subsequently For Super Technika V 4 x 5” The Super Techniko V 4x5” for the first time permits to selfadiust all additio- nally purchased rangeflnder-coupled lenses. Following the instructions below, exact correspondence between rangefinder and ground glass image is obtained. 1. Push the prematched coupling cam supplied with each lens fully into the cam mount, until an audible click is noticed. Pull out lens standard, insert lens and slide infinity stops into the rails of the upper track. 2 To guarantee exact adiustment, attach the transparent test image with scotch tape to the inside of a vertical window. Position the camera, mount- ed on a suitable tripod, parallel to the test image at a distance of about 15 feet (5 m) {picture 1). It is very important to exactly center and level the camera both vertically and horizontally. To facilitate this operation the use of a Linhof spirit level (ZYW) is recommended. When looking straight through the rangefinder ocular, the height adiustment of the camera should be made in such a way that the small circle of the rangefinder image appears in the center of the reference line A - B (picture 2). Exact alignment of the camera in relation to the test image is essential for the entire focusing range, it becomes most critical, however, for close distance focusing below 6 feet.3. To evaluate critical sharpness on the ground glass, 0 good optical magni- fier (Linhof optical magnifier, 8 x, ZYL) must be used. Before beginning the final adiustment, the magnifier ocular should be focused critically on the grain of the ground glass. 4. When looking through the rangefinder ocular, aim at the line A-B and turn focusing knob until this line is perfectly focused in the range finder. Lock the extension release to prevent an alteration of the focusing position now obtained. Press the spring-tensioned grips slightly and move the lens standard along the upper track, until the square pattern of the test image appears completely sharp on the ground glass (use optical magnifier). Cross-check by changing the focusing after releasing the locking lever. Focus the test pattern once more on the ground glass by turning the focus- ing knob. lf lens adiustment was correct, the rangefinder image must now fully coincide with the reference line A - B. ln case of any deviation, repeat the above procedure, until the required adiustment is obtained. 5. If adiustment was performed correctly, the rangefinder must now coincide with the ground glass over the entire focusing range. Finally, push the infinity stops against the lens standard mount and lock in this position by fastening the set screws.
