The focal length of a lens is defined as the distance from the optical center of a lens or the secondary principal point for a complex lens like a camera lens to the focal point sensor when the lens is focused on an object at infinity. The list above does not cover some rarer scenarios such as using a large aperture for Milky Way photos but you will realize them pretty quickly in the field.

The Importance Of A Focal Point

It uses a 163MP X-Trans CMOS sensor similar to that seen in the interchangeable lens X-Pro1 and X-E1 models but now with on-chip phase detection promising much-improved autofocus speed.

. The X100S sees Fujifilm revisiting the concept but while the external design is essentially unchanged its a very different camera inside. Eventually you should add your own points. Conversely longer focal lengths.

An important point here is that you will outgrow these suggestions organically as you become more and more skilled at exposure in photography. To understand this definition of focal length we need to define optical center as well. A lens optical center is the point usually though not always within a lens at which the rays of light from two different sources entering the lens are assumed to cross.

This is supported by a new. First lets define a few terms. Its a primary physical characteristic of a lens which can be measured in an optical lab.

Shorter focal length lenses provide a wider field of view but offer less magnification.
