Probably, all of us are very much familiar about different cameras, but only a few among having good awareness about the camera lens. Here is the best explanation about Camera lens that you want to know.

The Basics ..

Why ‘Lens’ is used in camera?

• Lens is used to transfer the reflection of an Object To Film (In Normal Camera)/ Censor (Digital Camera)
• Lens is used To Control The Light that falling to the film (In Normal Camera)/ Censor (Digital Camera)
• Lens is used to control the limit of eye vision on a focusing object, where it functioned as image sharpening, blurring etc

How lens can Create Images?

Lens capture the light (Photon) that reflects on an object and it transmits to the film for creating the images. So, more clearly when you click the ‘ON’ button of your camera, the shutter (The cover that is placed in front of your camera to protect the lens) moves out and the light rays from the object passes through the film (normal) or Sensor (Digital Camera), and the image will expose (Developed) on the basis of primary colors (Red, Green and Green).

How Lenses are Co-related with Focal Length?

Camera Lenses are classified on the basis of the basis of focal Length (f). The light rays from an Object converge through the lens and it meets at a particular point is called Focal Plane. So, the distance from the lens to the Focal Plane is called Focal Length.

Proportion- Focal Length: Focus Object: Lens

When The Focus Object is closer to the Lens, then the Focal Length Increases and the image will appear as Bigger.

More clearly, for close up shots the Lenses having a higher focal length will give you Good results, and in the Wide angle shots the lenses having a less focal length gives you Good results.

Practicability

1. If you’ve chosen a lens that having High focal Length (Above 135 MM), then the depth of the frame will Increase, and the focus object will get a closer view and resulting of this, the frame will get more audience attention.
2. If you’ve chosen a lens that having less focal Length (below 135 MM), then the depth of the frame will reduce and the focus object will appear as a longer view, and resulting of this, the frame will get less audience attention. Less focal length lenses are used in wide angle shots and establishing shots.
