This is a Nikkor lens due to the writing around the edges.
Nikon is a Japanese optical company that got its start in 1881. It has been one of the leading manufacturers in camera equipment since the early 20th century. It has managed to maintain its reputation over the decades. In the 1930s, Nikon added added an "R" to the Nikko lens brand, and it has been called Nikkor every since. Identifying Nikkor lenses is usually easy because they are clearly labeled. However, some lenses are old, banged up or carry a variation of the Nikkor label. These lenses need to be removed and more closely inspected.
Instructions
1. Remove the lens cap from the lens and look directly at the lens. There should be writing around the edges of the lens. If the lens says anything about Nikkor, Nikon or Niko--in the case of very old lenses--it is a Nikkor lens. If there isn't any writing or it is illegible, go to the next step.
2. Unscrew the lens from the camera body. This can be done by pushing the lens release button and turning the lens counter-clockwise. The lens release button is to the left of the lens.
3. Hold the lens so you are looking at the mount--the part that attaches to the camera. You are looking for the same words as before: Nikon, Nikkor or Nikko. If you do not see any variation of the Nikon name, it is not a Nikkor lens.
