A DSLR camera is a digital camera that features a single lens that allows light to enter the camera and be reflected either upwards or downwards into the camera’s viewfinder.
The mirror pops up out of the way when you push the shutter to take the shot.
The shutter then opens, allowing light from the lens to travel straight to the image sensor, where it is registered as an image or photograph.
This explains the acronym’s “SLR” portion. Instead of utilizing 35mm film, digital refers to the digital sensor.
To comprehend the differences between SLRs and DSLRs, keep in mind that the mechanics are the same, but SLRs store images on film while DSLRs store images digitally.
What Does DSLR Stand For?
DSLR is an acronym for Digital Single Lens Reflex.
The term “digital” refers to the camera’s use of a fixed digital sensor.
The term “single-lens” implies the professional camera employs the same lens for framing, focusing, and taking pictures.
This is not the same as a rangefinder or a twin-lens reflex camera. With these kinds, you can’t see the precise view from the lens that will take the photo.
You’ll have to rely on other techniques to set up the shot instead.
Reflex is a mechanism in which incoming light is divided or directed towards an optical viewfinder by a mirror. It gives you a precise optical perspective of the scene.
This mirror is semi-transparent and may be flipped up during exposure in SLRs and DSLRs. What’s more, it can be fastened in SLT-type cameras.
How Did DSLRs Come to Be?
Nikon developed the first DLSR camera prototype in 1986. In 1988, they released the first commercial DSLR camera.
Other DSLR camera manufacturers, including Canon, Fujifilm, Kodak, and Sony, flooded the market in the following decades.
DSLR cameras have only become more advanced since then, with the number of megapixels in image sensors continuously growing.
Digital noise reduction, focus speed, frame rates, and high ISO performance have all been prioritized.
How Does A DSLR Camera Work?
When light reaches a digital SLR camera lens, it is reflected by a mirror inside the camera body, allowing the photographer to see their subject via the optical viewfinder.
The mirror swings out of the way when the shot is taken, allowing light to pass through to the digital image sensor, which records the image on a Micro SD card.
This is quite different from mirrorless cameras, where light is propelled directly to the image sensor. The photographer or videographer sees what they’re shooting through a back LCD/TFT display or an EVF (electronic viewfinder).
Types of DSLR Cameras
While different DSLR cameras have different sensor sizes, these sensors are still large enough to capture enough megapixels to blow your smartphone camera image quality out of the water.
The two primary sensor types are full-frame and APS-C.
APS-C DSLRs have small sensors which cause low focal length, also known as ‘crop factor.’ This smaller viewing field can be improved with certain lens accessories.
However, it’s something to keep in mind when selecting your ideal APS-C or full-frame DSLR.
Full Frame DSLRs are the standard and have sensors that match the size of the 35mm film.
Why Do You Need a DSLR?
Fast AF (Autofocus)
DSLR cameras have advanced subject tracking, which allows for lightning-quick AF (autofocus), vital for sports and events photography.
Most digital cameras use fixed lenses with fixed focal lengths, which means less manual control.
A DSLR can use several lenses, giving you more options for your snaps, such as changing shutter speed, customizing DoF (depth of field), and shooting wide-angles.
Long Battery Life
Since the optical viewfinder uses less power than typical cameras, your battery will last longer, allowing you to spend more time taking pictures.
Since light is focused directly into the optical viewfinder, you can see the actual scene without the lag that some point-and-shoot cameras have. This means you’ll spend less time concentrating on your shot and more time filming it.
Plenty of storage
When you take a photo on an SLR camera, it’s stored on a film. With DSLRs, the image is saved on a memory card, which can hold a lot of pictures.
Therefore, when you have a DSLR, you don’t need to worry about expensive films; a single Micro SD is enough.
A DSLR camera is a great pick, whatever your budget or needs are. DSLRs are widely renowned for their single-lens mirror system, which allows you to preview the precise optical view of the shot you’re about to take.
So you’ll find these cameras handy in a lot of instances.
