What Does MM Means? MM. Meaning Abbreviation, Acronym

what does mm mean

The metric system is used by almost every country in the world for weights and measurements. The U.S. is one of only a few countries that do not use the metric system. The U.S. uses the customary system for units of measurement. Also, remember, these focal lengths we’re going to discuss are for a full-frame camera. Your focal length will be different if you’re shooting on a smaller sensor (like a crop sensor).

In everyday terms, the focal length number impacts how much you see and the angle of view when you look through the lens. For example, a focal length for a 16mm lens will show a much wider frame than that of a 200mm lens. Learn about the metric system, examples of metric units, and what the metric system is based on. To reach m from mm, we must jump three places to the left.

Another benefit of standard lenses is their focusing distance. You can be close to your subject and still get them in focus. You can harness the look and reach of multiple focal lengths from a single lens (saves a ton of time, money, and resources by having a good zoom lens instead of only primes).

  • As we can see in the chart, from mm to cm, only one jump to the left is required.
  • Now, whoever standardized the ‘name’ of a lens made it kinda difficult for the beginner to understand.
  • The point of convergence remains the same and can’t be changed.
  • Here, millimeters help us accurately express their length.

These days I primarily focus my efforts on this site, creating guides and tutorials that I wish I had earlier in my career. Each week I publish new tutorials on Photography, Photoshop, Lightroom, and Canva to help you unlock new skills and bring your creativity to new levels! Everything you learn here is backed by real experience, so you can finally skip the fluff and focus only on what matters. The super-telephoto lens is there to do wonders for sport and wildlife extreme photographers. A little bit more reasonable on the optic distortion, regular wide-angle lenses are still just as fantastic for landscapes (if not even more desirable for them).

We have to multiply the length by 10 every time we move from left to right. Also, for each time we move from left to right, we must divide the length by 10. An acronym sometimes used on Twitter when referencing a song or music that you think others should listen to.

The final result of your image depends on your lens, not the camera. A common misconception is that the longer the focal length, the better the lens. This is an understandable thought process, considering longer lenses are much more expensive! However, the larger the MM does not mean the lens is better – lenses don’t really work that way. Mm is an abbreviation that is a part of the metric system of measurement.

Millimeter Definition

Higher MM lenses are generally more expensive than lower MM lenses due to their size, as that involves more engineering and materials. A 24-70mm lens can zoom in and out, changing its focal length from 24mm to 70mm when turning the lens barrel. Lenses that don’t zoom are called Prime lenses, and the others are Zoom lenses. The functional distance between the front of the lens and its focal plane is how camera engineers tend to describe focal length.

What is the correct way to write MM?

Ma'am is a short form of Madam or Madame, the polite form of address for a woman.

Smaller numbers equal a wider field of view, while higher numbers are narrower, more zoomed-in perspectives (like a telescope or binoculars). A millimeter (abbreviated as mm and sometimes spelled as millimetre) is a small unit of displacement (length/distance) in the metric system. This is a loaded question – but I’m going to keep it in context with this article. We have a full-fledged article in the works that will explain, in detail, how zoom lenses and prime lenses are different. These lenses mimic the perspective the human eye sees the most, so they also tend to be very easy to use for brand-new photographers.

m Is A Great Semi-Wide Focal Length

As we can see in the chart, from mm to cm, only one jump to the left is required. We can use the following chart to find the approximate results for the conversion of customary units. “Millimeter” is a unit of length that equals one-thousandth of a meter. It is a small unit of measurement compared to the centimeter, meter, inches, and feet we are familiar with.

Territory includes Washington, Oregon, Montana, Idaho, Hawaii, Alaska, California, and Utah. Darrel has over 30 years of proven success and is skilled in developing relationships with internal and external stakeholders to drive superior business results. If you’re confused about the letter designations that stand for thousands and millions, you’re not alone. In fact, it’s one of our most frequently asked questions. Canon and Nikon sell a 200mm prime lens (f/2) that takes even better photos – but you’re looking at a $6000 price tag (versus ~$1400 for a 135mm).

m Is Considered The Most Versatile Of All Focal Lengths

The one little snag about telephoto lenses is that you need to be a bit away from your subject, as these lenses don’t focus up close. But this being said, short telephoto lenses still allow you to photograph in a smaller studio space and be able to focus. Because of the longer distance, short telephoto lenses can be used for action photography and wildlife. However, other telephotos tend to be a more popular choice for these subjects.

Standard lenses are the bread and butter for photographers. The benefit of standard lenses is the lack of optic distortion, so your subjects won’t have their proportions altered as a result. Here’s a fun example to understand why small units are important. Gulliver, a sea captain and a surgeon, ends up on the island of Lilliput, where people are only about 6 inches in height.
