Replacing the front element

    I have a lens that has a very faint scratch on the glass. So far, it
    hasn't cause me any concerns, and most of the time when I hold the
    lens up, I can't really see the fault.

    However, I would like to ask if I can get the front element replaced?
    The lens is a minolta and I tried to send a query via their website
    but the form goes dead when I press on the submit button. If you don't
    key in anything at all, the form woirks fine (makes you wonder what
    message are they sending).
    I had worse experiences with Minolta Singapore (and their parent), so
    I'm not really surprised at this.

    If it can be done, what kind of money am I looking to pay?

    Give Hagemeyer a try:

    Should be able to find a link to a service agent near to you. I've found
    ProGear at Chatswood NSW okay to deal with:

    So far the only effect is on your imagination. If it does flare up, run in
    some shoe polish and clean up the excess.

    You can but it won't be cheap.

    I am currently fixing my 80-200 due to a crack which happens out of the

    Cost me approx $200 on the labour and $60 for that lens element
    [with Maxwell here or $60 for the labour and $200 for the lens element if
    done over in Nikon Indonesia :D * very strange I know *]

    which is a the 2nd last element [== very small]

    I really don't know if I have to change my front ones which is an ED glass.

    Do you realise that replacing the lens may cause more harm than good. The
    service centre will most likely be unable to position the lens with the same
    accuracy as the manufacturer, so you 'may' have a decline in image quality.
    On the other hand, a scratch so fine that it is difficult to see will almost
    certainly cause you no problems at all, other than mental anguish. I would
    do nothing, other than get over it.

    I used the contact form on this website as well. I got the same
    results :-(.
    They don't have a service centre in the ACT, I'll probably have to
    give one of those in NSW a ring on Tuesday.

    Yeah it's true. When I first bought my camera, I fiddled with the
    focusing screen because there's a speck of dirt in the view finder
    that was so "distracting" even though it had no effect on the picture.

    I ended up having to replace the screen as I went too far and cracked
    it. Dumb.

    Shoe polish? You mean apply the neutral shoe polish cream on it?

    My suggestion is that you can consider the effect of making a mistake.

    I have read most of the replies.. here is my suggestion.

    If it really bothers you (it would bother me) then sell the lens on
    ebay. Be honest and describe the fault EXACTLY. Most people would not
    be bothered by a insignificant scratch.

    It may surprise you... you may even get more for the lens that it will
    cost you to import a new one especially if you add the service cost of
    replacing the element to the figure.

    For example

    while your putting shoe polish on it, you might consider also some sticky
    tape on the fron element as well, oh and when you are using shoe polish dont
    forget to use sandpaper. what a joke. Either leave it be if its not causing
    u problems in the prints or send it to Minolta and get it fixed properly.
    Either way anything you put on the front thats not made specifically for
    lenses (and elements which are coated in a very soft anti-reflective
    coatings) such as fluid and tissue u risk further damage...

    Thanks for all your inputs guys.

    I probably wouldn't send it for a replacement just yet as the pictures
    are still good. If it gets worse, I doubt I will get it replace either
    as the 300 odd dollars would probably be better spent on a new lens.

    Hmm ... ebay sure looks like a good place to sell stuffs.

    dust on a front element degrades the image not simply by being there, but by
    being something which scatters light. A scratch does much the same thing,
    causing a reduction in contrast and sharpness. Trying to fill a scratch with
    something with different optical characteristics offers little or no improvement
    over leaving the scratch alone.

    One of the oldest tricks in the book is to black out the scratch with boot
    polish or paint. Strangely (counter intuitively?) it works and works well.

    If it seems odd that a blob (or line) of black paint *doesn't* send your image
    all to hell, then consider the size of the big black blob in the middle of a
    catadioptric lens..

    Much of what you say doesnt kick in when the lens is wide open.

    remember the old advise with LF lenses, that it was better to buy the ones with
    the bubbles at the edges instead of at the middle?
