What is a DSLR Camera? How Does It Work?

A DSLR camera stands for a digital single lens reflex camera. In it, the main important parts are the lens, mirror, shutter, camera sensor, prism, and viewfinder. Let’s see how the DSLR camera works through the below diagram.

How DSLR Camera Works
  • First of all, the light enters through the lens, and it bounces off the mirror.
  • After it, the light goes through a special prism and beams through the viewfinder.
  • Then, it goes into your eye.
  • Now, whenever you press the shutter button, its mirror flips up.
  • And it exposes the camera’s sensor to light.
  • Incautiously, the viewfinder blackens, and the camera’s shutter moves to take your photograph.

Of course, the DSLR camera works quite smoothly, but it has a fundamental issue. Its mirror takes up a lot of space. Hold a DSLR camera in your hand, and you will realise how bulky it is. Its weight is not a big issue for a few photographers but for those photographers who shoot the whole day, travel a lot, and prefer to hold a small and lightweight package; a DSLR camera is not the right choice.

Here is where mirrorless cameras come into the picture.

What is a Mirrorless Camera?

A mirrorless camera is just like a DSLR camera. However, the basic difference between a mirrorless DSLR camera is that it does not include a mirror. Let us understand how a mirrorless camera works.

How Mirrorless Camera Works
  • First, lights enter into the lens. However, it does not bounce off the mirror and to a viewfinder.
  • Instead of it, the light straightforwardly goes into the sensor.
  • After that, the sensor is digitally projected onto the rear LCD and electronic viewfinder.
  • Now, whenever you press the shutter button, the sensor will record data, and you will get the photo.

As mirrorless cameras do not have mirrors, they are smaller than DSLR cameras. There are various types of mirrorless cameras available on the market, such as mirrorless cameras with interchangeable lenses, single in-built lenses, etc. In fact, if you have a smartphone, you already own a mirrorless camera. All smartphones contain mirrorless cameras.

In the next section, we will learn about some pros and cons of DSLR and mirrorless cameras in brief. And after that, we will discuss the key differences between the two based on some common factors.

Mirrorless Vs. DSLR Quick Comparison

Here is a quick comparison of mirrorless DSLR cameras based on a few common factors.



A mirrorless camera is compact, light in weight, and portable. On the flip side, the DSLR camera is large and heavy in size. Therefore, it is not suitable for people who frequently travel for shoots.

Battery Life

Battery Life

When it comes to battery life, the mirrorless camera offers shorter battery life as compared to DSLR cameras. The mirrorless camera’s electronic viewfinder needs battery power, and that’s why it is not the ideal pick if you want to go for long shoot days. The mirrorless camera’s battery life is shorter as compared to the DSLR camera’s battery life.

Shoot Speed

Both mirrorless and DSLR cameras can take photos at a fast speed. However, a mirrorless camera’s simple internal mechanics let it shoot fast as compared to DSLRs whenever there is continuous shooting.


Both cameras are expensive. However, in DSLR cameras, there are more accessories available. Therefore, a budget DSLR camera can provide the fresher photographer with more value as compared to a mirrorless camera.

There are limitations in the library of accessories like lenses when it comes to a mirrorless camera. However, in DSLR cameras, you will get a wide range of options for interchangeable lenses.

Image Stabilization

Image Stabilization

There is no mirror in a mirrorless camera, so there will be more image stabilization. As there are fewer moving parts in a mirrorless camera, you will get quieter and more stabilized photos.

Autofocus System

Auto Focus System

The autofocus system in the mirrorless camera makes use of the contrast-detection instead of phase detection. It means a mirrorless camera cannot measure the accurate distance between the lens and object, just like a DSLR can.

Sensor Size

DSLR camera contains a bigger sensor size as compared to a mirrorless camera. That’s why the mirrorless camera is not ideal for shooting when there is low light.

Exposure And Contrast

Exposure & contrast

When you use a mirrorless camera, you can preview the contrast and exposure setting on the screen before taking photos. However, the DSLR camera comes with an optical viewfinder. So users can see through the lens in real-time. However, if you are using a DSLR camera, after taking photos, you need to examine it and ensure that the exposure is correct.
