camera lens has a 50mm focal length, the digital camera’s focal length might be 4mm. So even though they are very different numbers they produce the same result because of the size of the imaging surface. So the “equivalent 35mm focal length” for this smartphone camera at 4mm is 50...
What is focal length? Focal length is the main optical property of a camera lens. It’s displayed in millimeters and by a number that looks like this: 35mm, 50mm, or 100mm. Lenses are named by these numbers and used when refferencing different types of lenses. Essentially, focal ...
This is one of the most versatile types of lenses.A standard or “normal” lens gives a perspective that is very close to that of human vision. Most kit lenses are standard zoom lenses. The popular RF50mm f/1.8 STM“nifty fifty” lens is a standard lens on a full-frame camera, ...
In the example of the two Nikon lenses illustrated above, the lens on the left is a 35mm film camera zoom lens with a focal length of 28-105mm. It is a popular zoom lens because it provides a good wide-angle (28mm) as well as enough telephoto reach for a good portrait lens (with...
The focal length of a lens is the optical distance from the point where the light meets inside the lens to the camera’s sensor. Learn more today.

Some of the terms in photography can be a little confusing. Take focal length, for example. We know focal length refers to the lens on our camera, but what exactly is focal length?Understanding focal lengthwill help you know which lens to purchase and how to use it for a wide variety ...
Note that focal length is a property of the lens, not the camera. Some lenses offer wide focal lengths, some offer standard (medium) focal lengths, and some offer telephoto focal lengths. Prime lenses are capable of photographing at a fixed focal length, such as 50mm, while zoom lenses ca...
Lenses with longer focal lengths, such as 200mm, give you narrower angles of view. The focal length of a lens is the optical distance (usually measured in mm) from the point where the light meets inside the lens to the camera’s sensor. “You can zoom in on your phone, but that’s...
In optics and photography, the focal length is the distance from the optical center of the lens to the imaging sensor when the lens if focused at infinity. The focal length is measured in millimeters. Focal length directly affects the size of the image captured, as it changes the angle of...
