Ballhead Operation (continued)
TENSION KNOB
(BZ-217T & BZ-226T BALLHEADS)
The tension knob is used to
control the amount of friction on
the ball in order to maintain strict
control when positioning it. The
tension knob is the medium-sized
knob, and it has a different look
and texture than the main and
panning locking knobs so you
won’t confuse the two, even if
you’re operating them by touch.
