Parts of a Camera and their Functions

Built-In Flash

A built-in flash bursts the light when the operator triggers the shutter button. It is built into the camera, which opens when we switch on the camera.

This built-in flash fix is in the upper position on the front or top side of the camera. It helps to get good clarity and quality of the image.

Mode Dial

It is a unique feature for video shooting mode. We can rotate the dial to select the mode as per the scene. There are creative and basic zones available.

In the creative zone, we can set functions as per our requirements. Whereas in the basic zone, the default setting gets selected per the scene.

There are modes like Priority, Aperture Priority, Shutter Priority, and Manual. In Nikon cameras, the short forms are P, A, S, and M, while in Canon cameras, the short forms are P, Av, TV, and M.

Shutter Button

The shutter button is to release the shutter while capturing the image. It works in 2 stages. When we press the button half, it triggers the AF to activate, and the complete pressing activates the shutter to release.

Red-Eye Reduction

After activating this function, it illuminates this lamp after half-pressing the shutter button. In the self-timer, it flutters for a specific time and stops blinking after the image is captured.

Lens Mount Index

It is a red or white dot to align the lens while fixing it to the camera.

Lens Release Button

This button helps to attach and detach the lenses to the camera. After pressing this button, we can rotate the lens freely to separate it from the lens mount.


It is a rubber coating on some parts of a camera to get a good grip during use. It helps to prevent the slipping of the camera during photography.

Lens Mount

It is an arrangement for the camera to attach the new lens. To attach a new lens, we have to align the lens to the lens mount and rotate it clockwise to fix it. 

Flash Button

The main function of the flash button is to force the flash to open before it is triggered. In some cameras, if we press the flash button, we can adjust the intensity of the flash.


The aperture is a donut-shaped ring that is inside the lens. The function of the aperture is to control the amount of light that reaches the image sensor. It regulates the brightness of the image.

Aperture helps to blur the background of any photograph.

Camera Body

It is an assembly of all the internal parts, which are covered by a plastic cover to protect from foreign matters. It was available in various sizes, designs, weights, and shapes per the manufacturer.

Parts such as lenses and extra flashes are not part of the camera body parts.


It is a protection against external light. 

Viewfinder Eyepiece

It is a rectangle-shaped frame on the rear side of the camera. It displays the image which we are going to capture. We focus on the object through the viewfinder while clicking the photo.

In modern cameras, we have an LCD that displays the image that we have to capture.

Some cameras come with a fully digital viewfinder, which gives various details such as shutter speed and aperture before clicking the picture.

Dioptric Adjustment Knob

Every person doesn’t have a clear vision to see the image through the viewfinder. Due to that, this knob helps to adjust the viewfinder clarity.

Live Shooting Switch

We can activate or deactivate the live shooting mode by pressing the movie shooting switch. By activating this mode, we can record live at any time with only one click and see it on the LCD.

Focus Point Selection

This button helps to activate AF mode, and we can manually focus with controller buttons.

Quick Control Button

By pressing this button, we can see all the settings and functions on your LCD screen to select as per requirement.


It is a controller that helps to move the menu up-down, left-right, to move the magnified display. It helps to select a required function during live shooting or photography. 

Erase Button

We can erase/delete unwanted images by pressing this button.

Playback Button

It helps to see the earlier images we have captured on the LCD monitor.

Menu Button

This button helps us to get all the functions of the camera. We can select these functions as per our needs and requirements.

LCD Display

The LCD monitor is the screen at the back of every camera. It displays all the settings, images, menu, and performance. We can magnify the captured image to see its clarity on the same LCD monitor.

It helps you to check the image quality to take a good shot. It also displays the live video that needs to be shot.

In most cameras, the LCD screen fixes at one position, but in some cameras, the LCD screen will flip out or swivel. It will help us to capture a picture that is a very difficult or awkward angle.

Main Dial

The main dial is on the front side of the camera. Its function is to adjust the shooting setting, such as shutter speed, aperture, etc.

Display Button

It allows you to On/OFF the display of the camera.

Power Switch

The power switch has 3 modes: ON, OFF, and standby. With this, we can power ON/OFF the camera. When we switch on the camera & keep it ON for a prolonged period, it automatically goes to standby mode to save power. 

Hot Shoe

It is a U-shaped fixture available on top of the camera. Its function is to connect the extra flash, radio triggers, external microphones, and light meters to the camera.

Small sensors and connectors help to send the signal from the camera to the flashing. So, it flashes at the right time during photo capturing.


Whenever we record a video, we can store them in memory. While playing this video, the speaker gives an audio sound. With the main dial, we can adjust the sound.

Strap Mount

It is for connecting straps to the camera. It makes it easy to handle the camera and protects it from dropping. So we can balance them while doing photography.


Understanding the various parts of a camera is essential for harnessing its full potential and elevating the quality of your photographic work. Understanding these integral elements empowers you to use a multitude of functions, resulting in more beautiful and exceptional photographs.
