    internal dust in lenses

    I have had internal dust in some of my lenses, and being a sharpness nut, that bothers me.
    Is there a tool kit available that would allow someone who is an ex rocket "scientist" who is pretty handy to clean the lenses myself? I have had problems with Zeiss for Hasselblad, goertz for LF, and lately, my Communist lenses for my Hasselblaski.

    It would seem a kit would be popular.

    Once you see the price for a professional cleaning you'll likely not worry about it so much. A bit of internal dust really isn't an impediment to sharpness.

    Dust won't cause a lack of sharpness, but may affect the contrast. I wouldn't worry about the dust. If you get the lens apart and don't get the elements back in perfect alignment, then you will have a sharpness problem. It is also almost impossible to eliminate all of the dust. Some will get in during the process of cleaning and assembling the lens no matter how careful you are. The only way to avoid it is to have a laminar flow workstation.

    Let a pro handle it, or you'll be sorry. I had a Nikon lens cleaned, lubed and adjusted on an optical bench by a certified Nikon repair shop for $50. I asked to watch him do it and it was a very humbling experience. I would never even try to do it myself. There are a million things that can go wrong.

    By the way, you're just doing this for that fuzzy feeling in your stomach. Lens performance is not visibly affected by a little dust.

    The quotes (and bills) I've paid in the past couple of years for such services have been 2 to 3X what you paid. Either that was a long time ago or you have a very affordable tech at your disposal!

    With a bit of patience, you can get it for free. Nikon frequently offers free lens cleaning at major events like Photokina or sales events at Calumet. In any case, I recommend against opening a lens without specific training.

    Smart move!

    You one can save oneself $100 in pro-repairs by using a small screwdriver and do it oneself, but then, one needs $300 to fix the damage one did with the screwdriver!

    If you can ensure a top notch dust free environment, get a spanner wrench and go for it. Its really not rocket science. But You may get more dust in there doing it by yourself, even though I do clean lenses myself, but then, i do understand that risk. Another thing you have to watch is scratching the paints off on the threads for the retainers.

    By the way, whatever I said about a screwdriver goes for a spanner wrench too!
