Focusing The focusing knobs are located on the inclinable drive housing. Is the focus movement too loose or too tight? Does the outfit tend to slide downwards? You can adjust the movement in accordance with the weight of the outfit and with your own personal requirements:
Hold the drive knobs firmly with both
hands and turn them in opposite direc- tions until you obtain the required degree of resistance during focusing.
