Dust in Canon EF 70-200L f/4 lens - Photography

Quick question. I haven't noticed it in my photos but there is a piece of lint/dust on the inside of the front element of my 70-200 lens. It's close to the middle of the element. Will I not notice it because of it being heavily blurred? If it is a problem can most camera stores pull the front element off to clean it? Thanks, Greg...

    Default Dust in Canon EF 70-200L f/4 lens

    Quick question. I haven't noticed it in my photos but there is a piece of
    lint/dust on the inside of the front element of my 70-200 lens. It's close
    to the middle of the element. Will I not notice it because of it being
    heavily blurred? If it is a problem can most camera stores pull the front
    element off to clean it?

    If it's on the front element, you probably won't notice it unless you're
    shooting a patch of uniform color. Even then, because of the focus
    point, it will probably appear as a faint smudge over a fairly sizable
    area.

    I wouldn't lose sleep over it, but if you do notice it popping up in
    photos, I'm sure your local Canon dealer will know what to do.

    Try to bring it into focus in the viewfinder against a light and dark
    background... not even a hint of it, right? Ignore it. Lenses, even internal
    zoom lenses breath and little bits of dust are always moving around.

    Cheers,
