How Exactly Do Camera Lenses Work? Lenses work similarly to the human eye and allow you to control the amount of light that enters your camera. Inside each lens is a series of convex and concave optical elements that work together to bend light and refract it into a single sharp focal point.

Lens aperture controls light that passes through the lens to the image sensor or film. This is measured in: F-Stops (Estimated Measurement) or T-Stops (Exact Measurement). You will normally find T-Stops used when describing the best camera lenses versus a standard digital photography lenses.
A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
If the camera is the ‘brain’, then the lens is the ‘eye’. It lets us view and capture our environment. Some photographers find that the lens is more important than the camera. Others believe that the camera body functions and limitations are more important.
Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the
A lens hood blocks strong sunlight and unwanted light. If your camera is a person, lens hood serves like a visor or a cap when you are in the sunny outdoors. Strong, unwanted light lowers the quality of your images. It causes distracting flares and ghosting.
Aspherical lens element The aspherical lens element has helped to improve the optical quality of camera lenses in recent years. You may have seen ‘Asph’ or ‘Aspheric’ marked on a camera lens or in lens specifications. It’s now widely regarded as a mark of excellence.
A fisheye lens is a camera component used for shooting extremely wide angles, typically 180 degrees. Also referred to as a “super wide” or “ultra-wide” lens, it produces an image that appears distorted, giving it a more abstract yet
When to use a Wide Angle Lens Because the distance between the lens and camera sensor is a lot shorter on a wide angle lens, the lens itself has to be wider in order to capture enough light to make an exposure. So the peripheral vision of a wide angle lens is broader, which means it “sees” more of what is in a scene.
Every digital camera has at its heart a solid-state device which, like film, captures the light coming in through the lens to form an image. This device is called a sensor. In this article we explain the different sensor types and sizes.
