Arca Swiss B-1

This ball head is considered by many to be the best ball head on
the market. It is relatively light-weight (1.7 lbs) and it will hold
a tremendous amount of weight for its size. You can use this head
for lenses as large as 600mm f/4 (some people do not recommend using
a lens as large as a 600mm f/4 on the B-1, but it will hold the weight).
The smooth action of the ball is also quite remarkable. It exhibits
almost no “stick-slip” or jerky action when tension is
applied to the ball. This makes for easy framing adjustments. The
action of the panning base is also quite smooth. The distance between
the center of the ball and the plate-support surface of the clamp
is 1.72”.
Problems with the Arca-Swiss B-1:
Before you buy one of these ball heads, you should be aware of some
problems with this ball head that have arisen over the years. There
are two problems that have since been rectified. The first was that
the heads produced during a particular time did not operate as smoothly
as others do. The second problem was that during a certain period
of production the quick-release clamp, when dropped into the notch,
would not go down a full 90° from horizontal. These are not current
problems, and we do not expect them to recur.
Lockup problem:
To avoid this problem, thoroughly read, and abide by the instructions
that come with your Arca-Swiss ball head. We believe the lockup problem
discussed below is not as serious as it once was, although it can
still occur with currently produced Arca-Swiss ball heads.
• If the ball is frozen and will not move:
If this happens, this is what Bryan Geyer of Really Right Stuff
suggests: “The fix is quite easy, and can be administered safely,
with no risk of any damage to the B-1 ball head. Here’s what
you do: check the small thumbscrew located on the main knob to confirm
that it is indeed jammed, and not free to rotate counterclockwise.
Then, get a firm grasp on the main locking control knob (you may want
to use a piece of cloth to help get a good grip), and force-rotate
that main knob clockwise (clockwise only—as if trying to lock
the ball). You will need to rotate this knob clockwise by about 1/8
inch of movement in order to free the internal lockup. When this is
done, normal operation is restored. Full hand force is quite sufficient
to accomplish this fix; no tools are required unless grip is physically
impaired.”
• If the knob is frozen, but the ball is free to move:
This happened to a customer (Trent Robeson). He was able to fix the
problem by heating the ball head up with a hair dryer for about 5
minutes. He then forced the locking knob clockwise. This broke it
loose.
• How to prevent your ball from locking up:
Arca-Swiss suggests that you leave your ball head loose while transporting
it in a car or airplane. In general it is best to leave the head loose
when not in use. Also, it is best not to over tighten the head; use
only as much force as needed.
