A lens is a device that contains lens elements. These elements are shaped glass pieces that bend light in specific ways. Each element within the lens has a different function, and they work together in harmony. A camera lens is a very special item. It’s absolutely necessary to capture great images. You could use a pinhole and get great results. But you would have little to no control over the final image.The lenses you own today could well be the ones you own for the longest period of time. If you look after them, they will last a lifetime. One of the biggest challenges with a lens is the need for sharpness across the entire width of your scene. This includes the corners. Camera lenses, like it or not, are the most important part of your kit.

1) The Focal Length

An essential attribute of a focal point is the central length. A focal point's central length is characterized as the distance between the focal point's optical focus and the camera's picture sensor (or film plane) when centered at endlessness. To comprehend this meaning of central length, we need to characterize "optical focus" also. A focal point's optical focus is the point (ordinarily however not generally) inside a focal point, at which the beams of light from two unique sources entering the focal point are expected to cross. More limited central length focal points give a more extensive field of view yet offer less amplification. On the other hand, longer central lengths give a more limited field of view however give more prominent amplification.

On DSLRs, the tradable focal point's central length is estimated in millimeters. The central length of a focal point is typically shown on the focal point barrel, alongside the size of the connector ring.

2) The Lens Ratio

At the point when you view the front finish of your focal point barrel, you'll see a proportion number (1:2.8, 1:2.8-4, 1:3.5-5.6, and so on), which is the most extreme opening of the focal point. The opening decides how much light the focal point sends to the picture sensor. The lower the most extreme gap worth will demonstrate the nature of the focal point as far as splendor. Excellent long range focal points convey a consistent f-stop all through the central reach (for example a f/2.8 at 35mm and a f/2.8 at 80mm); though on a lower quality focal point, the f-stop shifts as you travel up the central reach (for example a f/3.5 at 28mm, yet a f/5.6 at 80mm); you are losing in any event one stop of light as you zoom up the central length from wide point to fax. A focal point with a low f-number (wide greatest gap), is a superior quality focal point and permits you to accomplish more with it. For instance, such a focal point is "more brilliant," permitting you to take photographs in low encompassing light conditions, yet still register a quality openness.

What's more, these brilliant focal points will empower you to accomplish an extremely shallow profundity of field. It is to be noticed that any focal point that is f/2.8 or lower is viewed as an expert focal point, and will have a correspondingly greater cost tag.
