What does 600 mm lens mean?

Taking your examples, the lens with a 600mm maximum focal-length has the smallest angle-of-view and therefore will magnify a distant object more. This type of lens is mostly used for bird and wildlife photography.

What does 12 mm lens mean?

So on a Four Thirds sized sensor, there is a 2x crop factor. So a 12mm lens will give you the equivalent field of view of a 24mm lens on a full frame 35mm camera. To put it simply, it stands for the distance between the back element of the lens and the camera’s sensor or film plane.

What does 100 mm lens mean?

100mm is the length of the lens. In general, longer lenses magnify more than shorter lenses. 2.8 is the maximum f-stop of the lens. The f-stop is actually the ratio of the length of the lens to the width. Smaller numbers indicate a larger opening.

How far can a 800mm lens zoom?

Canon EF 800mm lens

What does a bigger mm lens do?

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. A number lower than 30-50 mm will take in a bigger view than you naturally see, while higher numbers mean focus will be on a smaller aspect of your view.

What does 1.8 mean on a lens?

Aperture sizes are measured by f-stops. A high f-stop like f/22 means that the aperture hole is very small, and a low f-stop like f/1.8 means that the aperture is wide open.

What mm means camera?

focal length
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).

What does 300mm zoom mean?

At 300mm the lens will have the equivalence of a 450mm lens on a 35mm film camera or Nikon FX (Full Frame) digital camera. Many P&S cameras will say they have a 8x or 12x zoom, that just means that the longest focal length is 8x or 12x longer than the widest focal length.

What’s the difference between 200mm and 300mm lens?

On a full-frame camera, at focal length 200mm, the diagonal angle-of-view is about 12 degrees. At 300mm, it is about 8 degrees. In other words, at 300mm, the image captures a narrower part of the scene compared to at 200mm.

What does mm mean on a camera lens?

You see, mm is the way we standardize a lens. The mm of a lens is its focal length. Whether it be a zoom lens or a prime lens, the mm of that lens is its focal length. So, What If I Wanted A Wider Shot – What Camera Lens Would I Use?

What do the numbers on a camera lens mean?

When there are two numbers that means the lens is a zoom lens, where you can vary the focal length over a range. The first number is the wide end of the range, while the second number is the telephoto end of the range. The price of a lens tends to increase as you go farther towards the extremes of focal length.

How do you know what focal length your lens is?

Most photographers have a pretty basic understanding about lenses. But if that mm number printed on your lens barrel is still a bit of a head-scratcher, it’s time for a crash course in focal length. Here’s everything you need to know. All lenses have an “mm” number printed on them somewhere.

What is the distance between a lens and the camera?

For example, in a 55mm lens, there are 55 millimeters between the lens and the camera’s image sensor. Now, this is actually pretty meaningless information to you because the lens is housed in a protective shell, so you couldn’t actually measure that distance even if you had a reason to (which you don’t).
