Cleaning lenses using Optex lens pen

    I recently noticed a product called Optex digital lens pen at a camera
    store. It contains a brush at one end and a tiny tip at the other end.
    The tip appears to contain something with black colour residue. I
    wonder what kind of chemical this is, and whether it has a benefit to
    be used for expensive camera lenses. Is it better to use a lens
    cleaner tissue paper and a clear liquid similar to the one used for
    your eye glasses instead? Thanks for the info.

    I haven't tried them yet, but I've heard those new digital lens pens are
    much better than the old analog lens pens.

    Does that mean the black stuff is 0's and 1's

    In digital terms, I think 0 represents the front element of the lens,
    and 1 represents the scratch that you just made in its front surface.

    You and me both Tony. Lens pens make me shudder just at the
    thought of using them, except maybe the very first time from
    new.

    Yes, they are an ideal way of storing those almost invisible pieces of
    grit that will progressively destroy the front and rear elements of
    your lenses. <g>

    I am getting good results with optical wet wipes, which only get used
    once. I started using them only on my glasses, but I was so impressed
    with them that I now use them on my camera lenses and filters too.

    I use UV filters all the time, only taking them off to use other types
    of filters. Every now and again I have to replace a scratched UV
    filter, but at a tiny fraction of the cost of replacing the front
    element of a lens. The only time I need to clean the front elements
    is when I have taken the UV filter off the lens for some reason.

    The optical wet wipes are a superb way of cleaning filters. I blow
    off the dust and grit first, with a blower brush. Then I clean gently
    with one side of the wet wipe (to remove any further grit without
    scratching) and more thoroughly with the other.

    I often get construction site dust on the filters. That tends to
    contain cement particles which are very hard and sharp. So I take the
    filter off and wash it under a running tap, then dry it and clean it
    again with the optical wet wipe.

    I have no idea whether these approaches are the best, but they do seem
    to work well for me.

    Save your money. Your best bet is a microfiber cloth and some decent lens
    cleaner. The nicest thing of all is that the best microfiber cloths can be had
    for a few cents each. Check your local grocery story and go to the
    window-cleaning products aisle. Look for "Windex Clean & Shine - Dry Microfiber
    Cloths". A box of 12, 11"x11" of them costs about $3. They have no chemicals or
    anything in them, just pure microfiber.They are a soft open-weave that traps any
    dust or grit on your lens. Much better than those expensive tight-weave cloths
    that cost a small fortune in photo shops. Cut them into 4ths and you have enough
    where you can dispose of them after every use or every few uses. Instead of
    grinding grit into your lens with the tight-weave microfiber cloths, the very
    soft open mesh in these captures that grit and keeps it away from your lens.

    For the best lens cleaner of all go to www.sciplus.com and get a product they
    sell called "Rexton - Optyl-7". An 8 oz. bottle is only a few dollars and will
    last you a lifetime. I divide it up into small dropper bottles and give it away
    to friends because you get so much for so little. I've tried many lens cleaners
    over the last 50 years. I have to maintain several large and expensive
    telescopes, their 1st-surface mirrors requiring special care, far beyond the
    care needed for simple camera optics. This lens cleaner has managed to remove
    grunge, tree-sap, and bug-juice that no other cleaner could touch. A drop or two
    of this cleaner on one of those open-mesh microfiber cloths and your
    lens-cleaning problems are completely solved.

    I have a box of those (branded "Opti Clear") that I bought
    somewhere on special offer ages ago then completely forgot
    about them until now. I just dug them out and you're
    absolutely right, they work rather well :)

    And I always wash dirty filters under the tap, always have
    done. Some people get too paranoid to use the obvious
    cleaning methods in favour of high-tech gadgetry.

    Only if the scratch was made losslessly. "Near lossless"
    scratch methods won't help you at all, no matter what the
    scratch-maker claims.

    You are shooting negatives, no?

    Or should that be yes?

    I have several brands, purchased from Lord knows where, but they all
    appear to work well.
    Why use tap water and detergent when there is some extremely expensive
    and technologically complex - but far less effective - solution to the
    problem on sale at Jessops?

    I bought a Kodak lens pen - similar to what you describe. It worked well
    for about three cleanings, then started to leave a residue. I think at that
    point I tossed it, in spite of the fact that the brush was still 100 percent
    functional. YMMV

    My question is about that black colour "liquid" What kind of chemicals
    is that? Is it really black in colour, or just because the colour of
    the tip is black? Is it something like a graphite powder (like the one
    used as a "puffer" to prevent key holes from rusting - non oil
    lubrication)?
    Would that black stuff damage the camera surface lens? I am a little
    bit wary to use it, and just only ise the brush. I was actually
    looking for a tiny "blower" to dust off particles from the lens. But
    the salesman told me to get this instead.

    Do you have a mind of your own, or do you always do what the salesman
    tells you?

  18. There's nothing wrong with a microfibre lens cloth.
