One of a camera’s most crucial components is the viewfinder. You can see and frame your subject with this rectangular component on the back of your camera. Some viewfinders are entirely digital, displaying information before the shot, such as the shutter speed, aperture, and ISO.Parts-of-the-camera-and-their-functions-1 (3)

Button Interface

On the top and back of the body, there are a lot of buttons that are set up to perform specific tasks. Some cameras let you customize a few buttons to your liking.

Flash Button

Some cameras with an integrated pop-up flash, and the flash button is present. Its primary purpose is to make the flash open before being activated. While holding down the flash button on some cameras, you can change the flash’s intensity by adjusting the flash exposure compensation.

Lens Mount

The mechanical component that enables the lens to attach to the camera is known as a lens mount. Only lenses that are compatible with your camera’s lens mounting system may be used. To guarantee customers will use their lenses, certain camera manufacturers use exclusive lens mounting methods.

Focusing Screen

The glass surface on which the image is projected by a camera’s mirror is known as the focusing screen. The focusing screen aids in producing a variety of focus effects, from clear, high-contrast images to bokeh and blurring.


The camera’s display provides the user with useful details regarding the pictures and the camera. You can adjust the exposure, ISO, shutter speed, and other camera parameters by changing the ones shown here. This display can be used to access various menus and modify your camera’s settings. Nowadays, the majority of camera screens allow you to see your image before pressing the shutter release button.Parts-of-the-camera-and-their-functions-1 (2)

Shutter Button

One of the most recognizable components of a camera is the shutter button. By pressing the button, the camera is instructed to open its shutter and snap a photo. The shutter button on DSLR cameras is given a second job: when it is halfway depressed, it activates the camera’s autofocus system.

Main Dial

On the front of the camera, the main dial is a cogwheel that you can turn to change the aperture, shutter speed, exposure compensation, and other settings. You can browse the photographs on the memory card on some cameras using the main dial.

Zoom Elements

It’s likely that your brand-new camera came with a zoom lens if you just bought one. Depending on your lens’ focal range, zoom lenses let you change between focal lengths, from wide to telephoto, by twisting the lens rings.Parts-of-the-camera-and-their-functions-1 (4)


Last but not least, one of the camera’s most crucial components is the battery. Without one, the majority of its parts will not operate. The ability to capture more images for longer periods of time with a long-lasting battery enables you to find the perfect shot.


One of the three pillars that determine how your photos are exposed is their aperture. The aperture is also the hole in your lens through which light enters. Depending on how much light you want in your exposure, these tiny, thin blades on this portion can contract or extend.

Autofocus System

The capacity of digital cameras to focus on a specific topic fast and automatically is one of their advantages over traditional film cameras. This is made possible by the autofocus sensor, a component of a lens that transmits data to the camera’s internal computer and instructs the lens to change its focusing components in order to produce a sharp image.

Relay Mirror and Reflex

In all SLR or DSLR cameras is a reflex mirror. A DSLR requires a mirror because, unlike rangefinder cameras, the lens is not on the same axis as the lens. You may see what the lens views by using the reflex mirror, which is a mirror angled at 45 degrees to reflect light from the lens to the viewfinder.
