Preparations (Step 3 Adjusting the Camera)

3-1 Back-focus Adjustment

At the factory, back-focus is set at the point for the widest range of use for CS-mount. However, it is necessary to readjust back focus if a zoom or C-mount lens is used or if focus cannot be attained using the focus ring of the lens. To adjust, follow the procedures described below.

In order to adjust back-focus appropriately, use the iris adjustment function and an ND filter to re- lease the lens iris before proceeding with the adjustment. (An ND filter acts to reduce the overall amount of light entering the lens equally over all wavelengths.)
