Mamiya 7 adjustments. Using a ground glass on the film plane of the camera I can check and adjust parallax of the viewfinder. Also, as seen in photos three and four, I use a chart with 60mm line spacing (the rangefinder baseline distance) to check and adjust the rangefinder. Using this chart set at a 1 meter distance from the camera, I can adjust the rangefinder for one meter, infinity and vertical alignment.
