Today I picked up a brassy Nikon SP with a 2.8cm f/3.5 lens. The SP is a chrome model, but so heavily used that much of the chrome has worn off. The lens looks eaqually well used, with much of the black finish worn off, but the glass looks perfect. Amazingly, despite it's appearance, everything on it works perfectly, and according to my electronic shutter tester, the shutter is almost spot-on. I am doing some film testing with it now, I ecpect it will take great photos.
