Millimeters, or “mm” for short, is the standard unit of measurement for the focal length of a lens. So when you see “mm” following a number or a pair of numbers on a lens, you will know that the number refers to the focal length (single number) or focal range (pair of numbers).
Is a higher mm lens better?
Focal length is expressed in mm and a higher number means a bigger zoom, while a lower number mean the lens can be used for wider shots. As a rough reference, the human eye is said to see about the equivalent of 30-50 mm on a full frame camera (more on that later).

Does MM stand for millions?
If we wanted to denote millions, we would show that as MM. M is the Roman numeral for thousand and MM is meant to convey one thousand-thousand — or million. To take it further; one billion would be shown as $1MMM or one-thousand million.
What is a 50mm lens good for?
50mm lenses are fast lenses with a fast maximum aperture. The most basic 50mm lenses are typically F1. 8 – a very wide aperture. This means they are great for low-light photography (e.g. low-light portraiture or indoor shooting) as they allow more light into the camera’s sensor.

the larger number, 105mm, represents the focal length when you “zoom in” on a subject. 35mm times three = 105mm, therefore this is called a 3x zoom. When you zoom in on an object, it will get 3 times larger in the camera. Prime lenses only have one focal length, for example, a 60mm lens is a prime lens.
