    Just bought this tripod for a video camcorder, but if
    I slowly track something on a diagonal both axes go
    stick-stick-stick-stick - Is there any hope for or a
    fix for this? (maybe it's the heat and humidity?!)

    assuming that you have the drag adjusted correctly and
    the locks released, you may have just bought a tripod/head
    that was too cheap to match your expectations.

    Good fluid heads tend to be expensive. I haven't bought
    one lately, but I wouldn't expect anything for under $1000
    to be silky smooth, and even then, I wouldn't expect to
    stay that way for long. Professional tripods and heads
    used to start at $2000-$3000. Hopefully someone will jump
    in with a tripod/head for less that is good enough to meet
    your needs and expectations.

    The only other thing that comes to mind is that you may be
    fighting against the motion stabilizer that is built into the
    camera. These are best turned off when using a tripod.
    The sort of motion they are designed to reduce doesn't
    exist when the camera is on a tripod, but the camera may
    try to compensate for the intentional motion you make when
    tilting and panning.

    I have not seen this specifically, but I have seen the motion
    stabilizer cause a little jiggle at the end of a move. It is the
    compensation being pushed off to the side in an attempt to
    smooth out the pan, then when you get to the end of the pan
    it tries to recenter itself. I could see how such a device might
    do just what you describe while trying to compensate for a
    move that is already smooth.

    I have certainly seen this effect with inexpensive heads, and
    with poorly maintained expensive heads.

    No, your first guess was the better: I can feel the stick even without
    the camera mounted!

    I've had good luck with the Bogen fluid heads tripods.
    I have the 3046 and it pans just about as good as most running 300
    more.
    Reminds me when I had to make a rig for smooth pans back years ago.
    We were stuck in a real backwater and couldn't get anything flown in
    for a couple of days so I built one using two 1/2 inch blocks of
    teflon and some heavy silicone grease.
    Just cut two pieces of the teflon into four inch discs and drilled a
    1/4 inch hole in the center of both. Greased the mating surfaces witha
    thin coat of silicone grease and bolted them together with a long 1/4
    inch bolt and a knurled knob to allow for easy setting of the tension.
    Then screwed a camera mounting plate on the top and a standoff channel
    on the bottom with a 1/4 inch hole in the channel center to allow for
    bolting onto a standard tripod head.
    It did the job to the customers satisfaction and all went well.

  5. You can try a couple of things.

    1: Pan the head 360 degrees a dozen times clockwise and counter clockwise.
    See if that loosens it up some.

    2: Add more weight to the head (in addition to the camera) and see if that
    smoothes it out any.

    But remember, you get what you pay for.

    It loosens it a little, but not quite enough. What, no grease?-)

    That's a good idea - I'll have to think about how to do it.

    You mean because I paid less for a "professional" model, I actually
    received an amateur model?-)
