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 directions until you obtain the required degree of resistance during focusing.
Hold the left or right fine drive.
Turn the other fine drive until the desired resistance during focusing is reached.
