What does DSLR mean?

DSLR is an acronym for Digital Single-Lens Reflex cameras. This means there is a mirror inside the camera which lets us look directly into the viewfinder and see out of the lens. We can see the image we will get when the shutter is triggered. As the shutter is activated, the mirror swings and the image sensor capture what we saw. With technological advancements, DSLRs began to be equipped with electronic viewfinders. It was one of the main reasons that gave DSLRs an edge and they became popular.

How does a DSLR camera work?

In the older version of DSLR cameras, light passes through the lens and hits a mirror inside the camera. The mirror bounces the light through the prism into the viewfinder where a shot is framed. In modern-day DSLR cameras, half of the light goes to the Optical Viewfinder (OVF) while the other half hits a distinct autofocus sensor. When the photographer takes a photo making the distinctive shutter sound, the mirror assembly flips and the light goes through the digital image sensor. Then, it captures the photo on the SD card. These image sensors create such a picture that leaves your smartphone’s camera miles behind.

Image sensors in DSLR cameras

The two primary sensor types are full-frame and APS-C. Full-frame sensors are standard and give a similar result as a 35 mm film camera. APS-C sensors are a bit smaller, resulting in a shorter focal length called ‘crop factor’. These sensors can be compensated by using specific lenses. You should keep these sensors in mind while looking for DSLRs.

Interchangeable lens in DSLR cameras

A unique feature of DSLR is letting interchangeable lenses on the same camera. They accept a diverse range of different lenses such as ultra-wide lenses taking in loads of detail, macro lenses which let us see macro detailing and telephoto lens which is perfect for amazing portraits. Buying lenses with different properties opens up great possibilities for professional photographers and offers them greater creative freedom. Also, people interested in space as a hobby can use cameras like Canon DSLR.

DSLRs are customisation-friendly

Along with interchangeable lenses, manual controls of DSLRs are where users can make a difference. General compact cameras have various modes like ‘sunset’, ‘portrait’, and ‘macro’. In most DSLRs, we see five modes as Full Auto (often shown as a green square), Program Auto, Aperture Priority (A or Av), Shutter Priority (S or Tv), and Manual. Barring Full Auto, users can have partial or full control over each of the settings to help create a picture as they envisioned. Users can partially or completely adjust aperture, shutter speed, and exposure to get the best output.

What is the battery life of DSLRs?

DSLRs consume less power as they don’t need to be digital all the time. This increases their battery life.

Autofocus feature of DSLR cameras

Most modern cameras come with autofocus. DSLRs have better autofocus features to focus and shoot with a cutting-edge speed to capture high-quality images. Autofocus allows users to use a DSLR like a point-and-shoot camera but with better quality. With all their formidable strengths, DSLRs do have some drawbacks. You can find them quite heavy compared to common cameras. Some folks have difficulty adjusting to the autofocus system of DSLRs. But despite its flaws, the DSLR stands tall among its contemporaries.
