I ended up with a second copy of this lens in pristine condition (sold my original copy to a member here).
This is one of my very favorite lenses. Incredibly sharp, dreamy bokeh, built like nothing else. More glass than I've ever seen in a fast fifty.
There is a tiny bit of wear on blades, but it is completely insignificant. Couldn't even get a picture of it it's so faint. Focus is buttery smoother, aperture clicks are firm. Glass is immaculate.
This is truly one of the great lenses ever made. I hate selling it, but I simply don't shoot much anymore and can't justify it sitting about.
$425 shipped/pp'd CONUS
