What Does MM Mean on Camera Lens? Find Out
When you are out in the market looking for a new camera, or even if you are just browsing through different models, you will come across a lot of technical jargon. Manufacturers love to use all kinds of complicated terms and abbreviations to make their products sound more impressive, but this can often be confusing for consumers who are not familiar with the lingo. One such term that you might have seen on camera lenses is “MM”. But what does MM mean on camera lens?
In simple terms, MM stands for millimeter and it is a unit of measurement that is used to indicate the focal length of a lens. The focal length is the distance between the lens and the image sensor (or film) when the subject is in focus. A lens with a longer focal length will have a higher magnification power, while a lens with a shorter focal length will have a lower magnification power.

Importance of Focal Length
Knowing the focal length of a lens is important because it can help you to understand the field of view and how your images will look. For example, a lens with a focal length of 50mm will have a field of view that is similar to what the human eye can see.
This is considered to be a “normal” field of view and is great for everyday photography. On the other hand, a lens with a focal length of 200mm will have a much narrower field of view. This can be useful for taking photos of distant subjects, but it is not as ideal for general photography.
There are two main types of camera lenses – prime lenses and zoom lenses. Prime lenses have a fixed focal length, which means that they cannot be zoomed in or out. Zoom lenses, on the other hand, have a variable focal length, which means that they can be adjusted to zoom in or out.
The MM on the camera lens indicates the focal length of the lens. For example, if you see a lens that is labeled as 18-55mm, this means that it is a zoom lens with a minimum focal length of 18mm and a maximum focal length of 55mm.
To sum it up, MM stands for millimeter and it is a unit of measurement that is used to indicate the focal length of a camera lens. The focal length is the distance between the lens and the image sensor (or film) when the subject is in focus.
A lens with a longer focal length will have a higher magnification power, while a lens with a shorter focal length will have a lower magnification power. Knowing the focal length of a lens is important because it can help you to understand the field of view and how your images will look.
