    Just got my new lens from B&H, the interesting thing is I noticed
    there's a few dust particles on the inside of the rear element. I can
    see it when look at the rear element, and I can also see if I look at
    the lens from the front with the rear cap removed. It shows up quite

    Should I be concerned? This is a manual focus Nikon 105mm lens. i
    can't see the spot when I see through the view finder, but if I look
    at the lens from the front, it show up quite clearly.

    otherwise the lens feels and operates fine. I know I won't have
    trouble exchanging it, just wondering if I should go through the
    hassle. It probably won't show up on the photo.

    Opinions? Would you exchange it?

    If the lens is brand new there should be NO dust at all. I probably would
    exchange it - I admittedly, can be terribly anal about dust particles. One
    of my shortcomings I guess.

  3. They all have some dust. Zooms are going to have more than non-zooms.
    As time goes on they will get more.

    If your eyes are good enough, I doubt if you can find a lens with no

    For the most part dust does little harm. A lot of dust can interfere
    with image quality however.

    I suggest that it is not a photographic decision. It is one of your
    tolerance. If it was a new lens, you should be able to ask for an exchange.
    If you eyes are good be ready for several before you find one with none.
    While I would not bother, it is your right to bother if you wish. After
    all, part of the fun of a new lens is pride of ownership and if that dust in
    interfering with that, then you did not get all you expected.

  4. Even if your new lens was completely dust free, it won't stay that way for
    long. Doesn't hurt the lens function at all. Just use it and enjoy! If
    you ever get into an environment where there is a *lot* of dust, such that
    makes the lens function gritty, then get it CLA'd and it'll be just as good
    as new.

    Should is the operative word here. Yes, They should not have dust, but the
    fact is they often do have dust (a speck or two) right from the factory.
    Shine a flash light through the lens and they show up like little stars.

    If the lens didn't come equipped with dust from the factory, it will soon
    get some dust from normal use. They are not air tight.

    A few dust particles cover less than 1/1000th the surface of the lens and
    are not likely to affect the image one bit.
