What Does MM Mean on a Camera Lens? The REAL Definition

Usually, ultrawide wide angle lenses are used for landscape and architecture photography, while normal lenses are versatile because they offer a neutral, undistorted angle of view. A millimeter (abbreviated as mm and sometimes spelled as millimetre) is a small unit of displacement bookkeeping for startups (length/distance) in the metric system. A higher mm lens is better for wildlife photography as it gives you a larger zoom, and allows you to take photos from much further away. If you think you will be taking photos from a distance, then go for a higher mm lens, above 100mm.

• Between 16mm to 24mm is best for landscape photography, 35mm to 85mm is best for portrait photography, and 300mm plus is best for sports and wilidlife photography.
• Also, for each time we move from left to right, we must divide the length by 10.
• The lower zoom ring is responsible for changing the focal length of the lens – the currently selected focal length can be determined by the number at which the white line is pointing.
• Many are marketed with language like “equivalent” or “35mm equivalent” along with what their field of view would match on a full-frame camera to make choosing the right lens easier.
• If you’re new to photography, you might have wondered what “mm” means in the name of a lens like the Nikon AF-S NIKKOR 50mm f/1.8G lens or the Canon EF mm f/4L IS II USM lens.

For example, the Canon 17-40mm f/f L lens, which is available for full frame Canon DSLRs, has a focal length of 17mm at the widest and goes to 40mm on the long end. The lower zoom ring is responsible for changing the focal length of the lens – the currently selected focal length can be determined by the number at which the white line is pointing.
