Camera Lens Numbering System . A camera lens (also known as photographic lens or photographic objective). The second number is the focal length.

Depth of field (or depth of focus) is a measure of the range of object distances within which the image appears to be sharp. And dn denotes mirrorless camera format. Φ = ϕ 1 + h 2 h 1 ϕ 2.
What do the numbers on a camera lens mean >
A camera lens may be made from a number of elements: Very often you’ll see a shortened notation with no units, of the sort “50/1.4.”. Each increment represents a reduction in the amount of light passing through the lens by 50 %. Everything can also be expressed as “50 mm 1:1.4” or “50 mm f1.4.”.

The focal length of any lens is measured in millimetres (mm). In exceptional cases, generally on older lenses, you can also find the numbers reversed: If you remove the lens from your camera, the only kind of image you can produce is white light. Some aberrations will be present in any lens system. Camera lenses have another interesting property:

Your camera lens may or may not have the “mm” printed on it. So at one end of the scale, you’ll find the infinity symbol, and at the other end, you’ll find the lens’s minimum focusing distance (i.e., the closest the lens can focus). And dn denotes mirrorless camera format. Mm numbers mean focal length. Φ = ϕ 1 +.

When comparing lenses, the two most important numbers are the focal length range and lens speed. You will see a number, a slash, and another number (# / #). So the 800d is superior to the 700d. Same as af, except it can report the distance between the subject and the lens and then reports that information to the camera..

If you remove the lens from your camera, the only kind of image you can produce is white light. The first number used to describe a lens is its focal length; The lens is what focuses light from what you see through the viewfinder into a tiny, (typically) 35mm spot on the back of your film, dslr, or mirrorless camera..

So, if you really want to blur the background of your photo as much as possible, you’ll want at least a 50mm f/1.8, and probably something like an 85mm f/1.8, 85mm f/1.4 or 105mm f/1.4.
