This is one of my favorites. It is a NIKON F mount, AI lens with constant speed at f/2. It is a regular/normal lens. It has no AF, only MF. This copy come from between 1977 and 1979. It is clean inside. Focus and aperture ring operate very well. No visible damages.

Performance

When it comes to picture quality it has very decent parameters.

As it has short focal length, shooting landscapes will be a little bit difficult with cameras below 10 megapixels. You will not be able to resolve too much details. Quite opposite with closeups or midrange targets. You can easily take pictures event wide open at f/2, but if you would like to be 100% sure that you will not have any kind of defocus, mist etc, please stick between f/2.8 and f/5.6. Use f/8 and f/11 only if necessary. Use only f/2 in low light or if you like to get some sparklings in the background. In terms of contrast and color, you get good ones.

Conclusion

Strongly recommend it. It is general purpose lens with huge potential and reasonable price. It is metal and glass built piece of lens.
