Here in the following article we are going to discuss about What is a DSLR camera. A Digital Single Lens Reflex camera, commonly abbreviated as a DSLR is a top-notch professional camera that comes with amazing features to capture the best quality images. 

Parts of a DSLR camera

Before you go on exploring about the different kinds of lenses available in a DSLR camera, it is important that you first know about the parts of a DSLR camera:


Compared to other cameras a DSLR comes with a much larger body and are heavy in weight. Whereas other cameras are lightweight and can conveniently fit anywhere you want, but for a DSLR camera you need a separate bag to carry the camera and with the tripod it is overall cumbersome to carry the equipment.


Lenses forms the most vital part of the camera, and this is exactly where you start taking your pictures, they basically comprise of the prime and the zoom lenses which allows you to capture images with a fixed or an interchangeable focal length.


Aperture forms one of the most vital parts of the camera which determines the amount of light entering the camera, which allows for maximum exposure of the image. The aperture is adjusted depending upon the focal length of the lens.

Image Sensor

An image sensor forms yet another vital part of a DSLR camera which processes the image from an optical image to digital or electronic signal to be further sent to the memory card for managing the output.


A flash is used to provide light to low or dim light scenarios whereas an image can be captured in a dark space, and forms an important part of a DSLR camera.

Differentiation Between The Prime And The Zoom Lenses

As mentioned above, a DSLR uses two kinds of lenses, the prime and the zoom lenses. Now here, an attempt has been made to provide a brief differentiation between the two.

The prime lens- A prime lens used in a DSLR comes with a focal length that remains constant, which means it allows maximum light to enter the aperture of the camera, put in more simpler terms, it allows more light to enter into the camera lens, for the time period the shutter is open. Since it allows more light to enter into the aperture, the pictures provide a wide exposure in frame.

The zoom lens- On the other hand a zoom lens comes with a focal length that can be changed depending upon the photographer’s convenience.

The main part played with a zoom lens is that it allows you to change the focal length without actually changing the lens.The varied focal lengths can be adjusted using the zoom rings on the lens which allows you to capture the best quality images, based on your convenience of course.

Differentiation Between Zoom And Telephoto Lenses

You have already read about the major differences in between the two kinds of lenses, now apart from the prime and the zoom lenses here is a further detailed differentiation again in between the zoom and the telephoto lenses.

You already know that a zoom lens comes with a focal length that can be changed using the zoom rings available on the lens, depending upon the photographer’s convenience. Now let’s see what a telephoto lens is and what are its uses.

Now unlike a zoom or a prime lens which has its own distinct properties, a telephoto lens can either be a prime or a zoom lens. In a telephoto lens you can capture distant images by zooming in to a maximum point whereas in prime there is a limited amount of magnification that cannot be changed. A telephoto lens is normally used in wildlife photography.

To conclude, DSLR cameras are readily available in the market today and you can afford it at the most reasonable prices, also there are various sites available from where are can acquire the link to buy the camera at a reasonable rate.


Cameras have always played an important part in your life and are an important medium to capture memories or anything that interests you. To cater to this need there are a million range of camera brands available in the market today that differ in cost as well as quality.

Now speaking about the quality, most of you would say that the DSLR or the Digital Single Lens Reflex camera is a much preferred one over the SLR or Single Lens Reflex camera.

And hence, in the following article we have tried to give a brief about all important DSLR vs SLR comparisons which we believe is surely going to give you enough insights in how a DSLR is different from an SLR, and which can work for you the best and which one may not.

SLR And Its Functions:

An SLR or a Single Lens Reflex camera is an analog camera which before DSLRs came into being had been quite common and popular. The mechanism of an SLR camera is quite simple when compared to its counterpart which is today is obviously the DSLR camera.

Basically, an SLR camera uses a single lens system and hence the name single lens reflex and consists of a prism and mirror which allows the photographer to see through the lens to compose whatever they want to capture. 

The usage of an SLR camera it seems is much hassle free as when compared to that of a DSLR. All that a photographer needs to do is just press the shutter button usually situated on the camera head and a very simple mechanism starts acting where the camera mirror flips to release the sensor along with providing an adequate amount of exposure to the image to be captured.

We already explained DSLR and its function above in the Article.

A Brief Comparison Between DSLR & SLR

Now let’s make a clear comparison in between the two cameras so that you can decide which is the best among the two:



  • A DSLR refers to a Digital Single Lens Reflex Camera.
  • A DSLR uses digital image processing system.
  • With more advanced DSLRs coming into the market , the cost of the DSLRs are getting more expensive.
  • The mechanism of DSLR is really complex and requires high expertise to operate them.
  • A DSLR gives the best quality image with a proper exposure maintained.


  • An SLR refers to a Single Lens reflex Camera.
  • An SLR uses an analog image processing system.
  • SLR cameras are not much available nowadays and if at all it is, they are easily affordable at best prices.
  • The mechanism of a SLR is not that difficult and any lay man without experience too can easily operate them.
