What is a DSLR Camera?

DSLR stands for Digital Single-Lens Reflex, and it this post, we will go into the details about what it really is as a DSLR camera is still today the favorite of dedicated photographers. So let’s see what it is, how it works and how you should your next camera.

The reflex system was created in 1861, but the first camera with this system came out in 1884 in England and it remained as the standard system for many decades. Today, they are used with the same system, with only change in one thing and that is the material sensitive to light.

In the age of analog photography, a light-sensitive material was used, and this material was known as film or ‘rolls’ for the less technical ones. Today, digital photography also uses light sensitive materials but now there are small digital sensors that came to replace the film. Easier, cheaper and more common for all, the digital photography quickly became the commercial standard.

Now here we will have a look at the components of the system and how it works.

  • Front lens elements
  • Mechanism of approach
  • Diaphragm
  • Focal plane shutter
  • Film
  • Belt fastening
  • Trigger
  • Control of speeds
  • Frame counter
  • Rear viewfinder
  • Flash Shoe
  • Focus ring
  • Pentaprism
  • Reflex mirror

DSLR cameras are the system preferred by photographers for a simple reason, as they can actually see the light that is passing through, which allows them to see the real picture to be taken.

A clear comparison with bridge cameras is that we see the scene processed by a few chips through a screen that may show us an unbalanced scene of light and color because it may have a slightly unrealistic calibration. That is why the DSLR camera is preferred.
