very fast lens (f/1.8 is pretty great), manual focus which can be a little awkward but that's ok with me
in my camera i need to use manual mode with this lens, so i need to adjust ISO, shutter speed, and aperture manually, but this is all as expected
the lens came in great shape, the focus ring slides well, and the aperture ring feels good too. There are little notches in the aperture ring at each stop (so there's a notch at f/2 which is unlabelled as well as the labelled f/1.8)
Note: I believe "Nikkor" is a mislabeling on this product, as this is the Series E lens
I'm not a pro so I can't evaluate this lens well, but it's fun and I like it.
