Aaton Camera body 25Viewfinder tension adjustmentThe screw (B) at the base of the viewfinder, allows you to modify the viewfinderleft/right lateral friction. Turn counter-clockwise to increase the friction. Turningthis screw until it reaches its stop locks the viewfinder left/right movement.The friction adjusting knurled screw (C), located on the front of the viewfinder,can be used to adjust the tension of the eyepiece swivel, depending on theoperator’s preference and on the type of viewfinder being used. When usingthe standard eyepiece, tension should be relatively light to allow for movementwith a moderate amount of pressure. When using a finder extension, tensionshould be increased to support the additional weight.To adjust the tension of the swivel, rotate the knurled screw (C). To increase thetension of the eyepiece swivel, rotate the knurled screw clockwise; to decreasethe tension, rotate the knurled screw counter-clockwise.Adjusting the viewing horizonIf the rotation of the image seen through the camera’s viewfinder does notexactly match what is seen with the naked eye, there is a fine adjustment thatcan be made to the image’s relative horizon. Locate the knurled knob (D) loca-ted on the top of the viewfinder. While looking through the viewfinder, turn theknob in order to adjust the image upright position. Note that the knob needsto be turned 180° when installing an eyepiece extension.BCD
