The Nikon DE-1 is the standard unmetered prism for the Nikon F2. This one is black, and is in excellent cosmetic condition, except for a very shallowindent on one side (visible in the image, and somewhat camouflaged by the leatherette covering) and some light paintwear on the same side. You may have noticed the “light prism marks” in the title, so let me explain what that means: there are a few small scratchesin the prism surface that would sit closest to the focusing screen. These do not affect function, but the marks kind of look like specks of dust through the viewfinder when in use. Does that sound like it might annoy you? If so, this one might not be for you. But if you think you can live with it, this is otherwise a nice looking prism.
