What do the letters on a lens mean?
Your camera lens may or may not have the “mm” printed on it. You will see a number, a slash, and another number (# / #). The second number is the focal length. A lens stamped 1.8 / 55 means that the focal length is a fixed 55mm. Prime lenses have only one focal length, while zoom lenses have a range of focal lengths.

- The first number or pair of numbers indicates the range of available focal lengths in millimeters.
- The lens speed is listed after the small “f” and the slash.
What does A and M mean on Nikon lens?
A = Full Auto, with no Manual Override. You’d have to actually switch to “M” to focus manually. Also in older lenses, if the camera was set to Automatic focus, and one turned the focusing ring, there’s a good chance one will destroy the automatic focus of the lens itself.
What’s the difference between AF P and AF-S?
AF-P lenses use a “Pulse” motor or “Stepping” autofocus motor and are even quieter and smoother to autofocus than an AF-S lens, making these lenses ideal when shooting video with a DSLR. The DSLR camera bodies that do feature a focus motor can utilize AF and AF-S lenses.
