After being shipped with a D80 without objective, this was one of my few options, an old manual 55mm from the 70s. I was intrigued by the fact it was f/1.2 and quickly decided to give it a try.No automatic focus, no aperture indication, no auto ISO is the result of using a manual obj on D80. On the plus side, there is a focus indicator, but it does not work in low light. While not having automatic focus is a real pain (and even with the indicator, it does take quite some time), not having exposition information is no big deal, it's quick to change settings and take several pictures. In many situation you don't need to change exposition dramatically and in the end you get used to evaluate it.I went to the forest next to my parents place for a walk on a dark winter day. And here are some shots I got. I was shocked by the luminosity in these conditions.
