I had another lens in my jacket pocket when I was shooting our office bake-off two days ago.
I like to call this "old glass" my "evergreen prime lens", the lens is the Nikkor 50mm f1.4 AI, a manual focus gem.
This lens was very popular in the 70s, it came as the "standard lens" with some Nikon models.
I like it because it is very fast and really sharp images can be capture after f2.8!
