Anti-static dusters?

    I have had some trouble keeping my lenses and filters dust-free. The
    various micro-fiber cloths--and I have tried a lot of different ones--
    leave tons of lint behind, if you bother to look with a bright, narrow-
    beam flashlight. The various aerosol dusters, even the ones sold in
    camera stores, leave a residue behind. The squeeze-bulb dusters can't
    blow with enough force to remove the lint, but I think that electrostatic
    attraction may have something to do with that. You used to be able to
    buy a squeeze bulb duster with a brush and a bit of polonium on the end;
    the radioactive decay of the polonium would ionize the air around the
    tip and reduce static. Of course, they don't sell those anymore, and
    any old ones would have gone through too many half-lives to be useful.
    Are there any modern alternatives?

    You can buy new polonium dusters from Adorama for a hundred bucks or so.
    The refills are also available (they're rated for 5 years). One of the
    Amazon reviewers got a brush that was only 90 days away from its
    expiration though, so buyer beware.

    Most folks just use a LensPen.

    Yup! I still have one of those, bought around 1980-83 packed away with
    my various turntable accessories. ;-)

    There are good lint free cloths, and a good recommendation are always PEC pads.

    Also a good combination is a Giotto's Rocket bulb blower(puffer) and a
    soft 1''-2'' brush. Use the blower to blow off any loose dust. Then
    with a clean brush (free of oil from fingers etc.) start by applying a
    few puffs from the blower to the bristles. This does two things, first
    removing any dust on the bristles, second applying a negative charge to
    the bristles. Now brush off any persistent dust from your lens and
    camera body, stopping frequently to reblow the brush to clean off
    collected dust and recharge. Be careful not to touch the bristles with
    your greasy fingers.

    For antistatic and heavier dust removal try these guys, they are a good
    source of cloths & brushes, even an ionizing air gun:

    I have a couple of their "Tiger cloth" lint free antistatic cloths abd
    a couple of their brushes.

    ....and one of these kits is handy to have in your bag

    For other cleaning supplies I usually go to Micro-Tools, which has US
    and European store fronts, & Photographic Solutions

  4. Good Lord, over $100 for the 1"size? I used to sell those in my camera
    shop for about twelve dollars in the early 80's! I looked up the
    manufacturer's web page - they're still in business, to my surprise -
    and the current version of the product says it should be replaced every
    18 months, and are therefore freshly made to order.

    I remember the 80's ones being rated for several years.

    You could construct one from the Americium-241 pellet from inside a smoke detector and a standard Lenspen, but I believe the Americium-241 has less energetic alpha particle emissions than the Polonium used in the traditional brushes. Which means you have to mount the pellet as close to the lens surface as possible, within 1/2 inch. The upside is the source has a much longer half-life than 12 years so it won't wear out.

    There are many electric equal charge static eliminators, but most are not
    portable. They emit pos and neg ions through ac high voltage. I found this
    with a quick search, I'm guessing it operates the same manner.

    Well, $12 in 1980 is $37 today! If you sold it for $12 in 1970, it would be
    $78 today! :)
