What Is A DSLR Camera?
A DSLR camera is a type of digital camera that has a system of mechanical and reflective mirrors. This system will reflect the light from the lens to the viewfinder of the camera.
For more specific, let's find out about the term DSLR. DSLR here stands for Digital Single-Lens Reflex.
“Digital” refers to the digital sensor that the camera uses.
“Single-lens” means that there is only one lens in the camera. This lens will do all the tasks including framing, focusing, and capturing the image. The single-lens construction allows you to see the view that you will shot through the lens.
“Reflex” is the mirror system that transfers the light from the lens to the camera's viewfinder.
A DSLR camera consists of the following sections.

How Does A DSLR Camera Work?
To take a photo with a DSLR camera, first, you will look into the viewfinder. The image you see will be the image on the photo after you take it.
A DSLR camera doesn't have lags like other cameras. Because its sensor needs to transfer the displayed image to a separate digital screen.
The image will enter the camera in the form of light rays. These rays will be reflected upwards by the flip-up mirror to the camera chamber.
Then, they will go to the pentaprism system. This system will direct the light so that it passes through the viewfinder to your eyes.
When you capture the image, the mirror will flip up. The light rays will pass through this mirror. Then, the shutter will open, and the lights go to the digital sensor.
The shutter will stay open until the sensor completes capturing the image. After that, it will close, and the mirror will return to its position.
Next, the processor of the camera will take the image data from the sensor. It will convert the data to a suitable format, then record it on a memory card.
This process happens in a very short time. Normal DSLR cameras will do this process 3-10 times per second. Some professional DSLR can do 11 times per second. You can watch this video to know more about this process.

These sensors are large and work well in every situation, even in the lack of light. The larger the sensor, the more light it receives, the sharper your image will be.
Besides, DSLR cameras have fast, constant, and effective autofocus. So, they can capture any movement.
The quality of the lens also affects the autofocus level. But in general, a DSLR camera will focus faster than most other cameras.
