The Markins quick release shoe or clamp is of the pro ball
heads industry standard dove-tail style, beautifully finished
and now with and even rounder contour. The quick release clamp
knob requires just half a turn to release the plate to slide
in or out again.
The
friction limit adjust dial is easy and smooth to turn with
the tip of a finger.
To set the ballhead for a given set of gear, start by mounting
it into the quick release shoe (clamp); then, holding the
gear in your hand so it won't drop, loose both the progressive
friction control knob and the friction limit adjust dial.
Then turn the progressive (big) knob clockwise only enough
so one can move the mounted gear but will stay put if untouched.
Then turn the friction limit adjust dial clockwise -with the
tip of the finger- as far as it can go (without forcing it)
to lock the ball in place and still able to move the camera
into any position without having to touch the controls. With
the friction limit adjust dial (small) turned in. It is now
impossible to turn accidentally the clamp knob back to a position
where the gear will fall. That's it. You have found its "sweet
spot"
If you still want to fully lock the gear, just turn clockwise
the progressive friction control knob a little, until you
cannot move your camera at all. It will take a small fraction
of a turn to remain fixed and you are all set. But this is
not necessary and will just slow you down when making changes
in composition. This is a pro ball head, not a vise.
The
friction limit adjust dial has to be re-calibrated
only when and if your gear gets a lot heavier or a
lot lighter.
You want to be able to smoothly move the camera into
shooting position to make final composition adjustments,
but without creep, slip or drop if you let go and
without further unlocking and relocking the ball.
This is what the extra load capacity is for.

When
mounting the ball head on a Bogen/Manfrotto tripod, it has
been advised by previous users of other ball heads and the
manufacturer to be careful not to over tighten the three
screws under the tripod head mounting plate, to avoid excessive
pressure on the bottom of the panoramic base, inhibiting
its designed smooth glide. Others might prefer to use a
"lock tite" type of semi permanent (blue, not
red) plumbing glue instead of the screws.
Some
users with not excessively heavy setups find unnecessary
to do either and opt for simple nail polish on the threads
or nothing at all; others, resort to tightening it with
a rubber strap wrench.
