Minolta Metal Lens Hood The marking "D57KB" is on the back, but I don't remember which lens it was for. Judging by the length, it's likely for a 50mm to medium telephoto lens. It's a slip-on, screw-down type. Measuring the diameter, it's about 58mm, so perhaps it's for a lens with a 55mm diameter. Condition: There are several paint chips on the tip of the hood. There are some scratches on the sides. The silver mounting part has scratches, scuffs, and dirt.
