    NEVER DO THIS TO A LENS YOU LOVE IF YOU HAVE NEVER DONE THIS BEFORE! Can't stress that enough.

    I can't offer step by step, but I have taken a couple of fixed focal length lenses down and cleaned them and reassembled and they worked fine except for one thing. Watch out for the little ball bearing and the spring that creates the click as you turn the aperture ring. This is located in a little recess in the inner housing of the lens behind the aperture ring. Second thing, get a set of spanner wrenches before you start. You can get these from eBay cheap enough. These little ditties are priceless and save alot of time of lens scarring do to using the wrong tools. Be careful, use common sense, don't continue past what you are capable of and good luck.
    Thank you.

    Jim-

    It's a Quantaray lens. It isn't worth the time or money to try and repair. Just replace it. Also, as a separate note, please turn off your caps lock. When you type in all caps, it's as if you were standing next to someone and shouting.

    PRESS '+' ON YOUR KEYBOARD TO INCREASE THE SIZE OF THE LETTERS ON THE SCREEN.

    Then maybe I can try to read what you have written.

    That does not work on all computers, mine--but on most browsers if you click on "view" there is a line there for increasing text size.

    You're right Bobby, I often forget I'm one of the few people who use Opera. It's a browser shortcut, not a computer function.

    Zoom lenses are so complex that I think a casual repair attempt is just asking for trouble -- and taking apart is much easier than reassembling! Either replace the lens, or live with the fungus (and are the results so obvious? You may be able to live with it), or send it to an experienced repairman. Essex Camera in New Jersey seems to be able to do almost anything; start with them.
