1. Ultra-wide lenseshave a focal length of less than 24mm (all of these numbers are in full-frame terms). They capture incredibly broad views. However, because of this, they often present a distorted or exaggerated view of the world. They are great lenses forlandscape photography, and they...
Focal Length and Angle of View Therefore, optics are used to bend light in a way that moves the nodal point forward away from the sensor, making the focal length distance purely theoretical. This is why, in modern photography, a listed focal length is merely used to indicate that lens’ ...
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...
Both compression and other types of distortion are useful tools not only in photography but also videography, where the choice of focal length can impact what is emphasized in a scene. Also, a great example of how these effects impact how a face is rendered to the viewer can be seen via ...
[Note that since most camera lenses are made up of more than one lens elements, the definition "middle of the lens’ is adjusted slightly.] The focal length of a lens is usually displayed on the lens barrel. Pictured below is a Nikon lens with a focal length of 50mm. The maximum aper...
Photography is full of fancy terms, but we are here to explain it all to you in simpler terms. Today we are focusing on focal length.
To find the focal length that is right for you,experiment and try out different lenses until you find the focal length that best suits you and your shooting style. Who doesn’t love to try out lenses anyway? Have fun with it! The bottom line is, photography is fun. A person can shoot...
What is Camera Focal Length? Focal length is a number that is vital to photography and photogrammetry but often misunderstood. What is focal length? A strict technical definition of focal length is difficult without providing a lot of background in lens theory, so we will use a simplification....

This would be a mildly wide lens according to the usual definition, since the focal length is somewhat shorter than the sensor width. However, this image is only 3 megapixels, while the camera itself delivers 12 megapixels. It's entirely possible that this image was cropped, which would ...
