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:

hands and turn them in opposite direc-
tions until you obtain the required degree
of resistance during focusing.
