A wide angle lens is a type of lens that allows you to capture a wider field of view than a standard lens. These lenses are popular in landscape, architectural, and other types of photography where it is important to capture a large area in the frame. But how do wide angle lenses work, and what factors should you consider when choosing one?

The field of view of a lens is determined by its focal length, which is the distance between the lens and the image sensor when the subject is in focus. A wide angle lens has a shorter focal length than a standard lens, typically between 16mm and 35mm for a full-frame camera. This allows it to capture a wider field of view, making it ideal for capturing expansive landscapes or large groups of people.

One of the main characteristics of a wide angle lens is its ability to distort the perspective of the image. Because it captures a wider field of view, objects that are closer to the lens will appear larger in relation to those that are farther away. This can be used to create a sense of depth and drama in your photographs, or to emphasize certain elements in the frame.

Another factor to consider when choosing a wide angle lens is its maximum aperture, which is the size of the lens opening that allows light to pass through. A lens with a larger maximum aperture will allow more light to enter the camera, which can be useful in low light situations. It can also allow for shallower depth of field, which can be useful for creating a blurred background effect.

In conclusion, wide angle lenses are a useful tool for photographers looking to capture a wide field of view and create a sense of depth and drama in their images. By considering factors such as focal length, perspective distortion, and maximum aperture, you can choose a lens that is well-suited to your needs and style of photography.
