What is a DSLR camera?
First, what does DSLR stand for?
DSLR stands for Digital Single Lens Reflex:
-
Digital means the camera features a fixed, digital sensor.
-
Single lens means the camera uses a single lens to frame, focus and take a photograph, so you'll see the view from the lens that will capture the shot.
-
Reflex describes a system where a mirror directs incoming light towards the optical viewfinder. In DSLR cameras, the mirror flips up during exposure.
So what is a DSLR camera? A DSLR camera is a type of high-performing digital camera that allows interchangeable lenses. This ability to change DSLR lenses makes the camera more versatile and gives photographers more styles, functions and looks to explore in their photography.
DSLR cameras were first made in 1999, and have generally replaced SLR cameras since. They're popular with both beginners and professionals, produce high quality images and allow photographers to see the image they're capturing directly through the viewfinder, helping them visualise their shots better.
How does a DSLR camera work?
DSLR cameras use reflex mirrors (or prisms) to reflect light into the optical viewfinder. Light travels through the lens and is reflected by a mirror or prism in the camera body, enabling photographers to see the subject. When the shutter is released, the mirror moves, and light passes through to the imaging sensor: this results in your photograph!
What’s the difference between a DSLR camera and an SLR camera?
The main difference between a DSLR and an SLR camera is that DSLR’s record images using a digital sensor, whereas SRL’s use film.
Benefits of using a DSLR camera
There are many benefits of using a DSLR camera, including:
Interchangeable lenses
Interchangeable lenses make cameras more versatile, and mean photographers can experiment with different styles and techniques to enrich their skills. From adjusting shutter speeds to trying out wider angles and more, you’ll be able to capture images like never before.
Great battery life
DSLR cameras have a good battery life, so you won't need to cut your day out short to go back home and recharge your device.
High-performing autofocus
Advanced subject tracking and quick autofocus on DSLRs makes them great for capturing pictures and videos at events.
Storage
DSLR cameras use memory cards, meaning you'll be able to store lots of photos without spending money on film.
No delay
As light passes directly into the optical viewfinder, there's no lag on DSLR cameras.
Great image quality
The large sensors in a DSLR camera guarantee great picture quality.
Lots of accessory options
It's easy to add attachments and accessories to DSLR cameras; choose mounts, triggers, flashes and more to personalise your device.
Drawbacks of using a DSLR camera
Cons of using a DSLR camera include:
They're big
This isn't necessarily a drawback, and many photographers don't have any issues with the bulkiness of DSLR devices. However, if you're looking for something lightweight and compact, a DSLR isn't the best choice.
Limited display options
The optical viewfinder on a DSLR camera won't show the current exposure, so you won't be able to tell if your image will be exposed or not by looking at it.
Extra cost for accessories
While it's great that you can add attachments to your DSLR camera, these are an extra expense.
Alternatives to DSLR cameras
Let’s look at a few alternatives to DSLR cameras:
Mirrorless cameras
Mirrorless cameras work without a reflex mirror; light reaches the digital sensor directly and the image is displayed on the camera’s LCD screen, enabling users to experiment with settings before capturing the shot.

DSLR vs mirrorless cameras:
The main difference between DSLR cameras and mirrorless cameras is that DSLR cameras use reflex mirrors to divert light into the optical viewfinder, while mirrorless cameras allow light to pass directly to the digital sensor. Here are a few more differences:
-
Mirrorless cameras are more compact than DSLR cameras.
-
You can check exposure and contrast before taking photos with mirrorless cameras.
-
DSLR cameras have a better battery life than mirrorless cameras.
-
DSLR cameras are usually cheaper.
-
DSLR cameras perform better in low light.
-
The autofocus system on DSLR cameras is generally better than that on mirrorless cameras.
-
When it comes to videos, mirrorless cameras perform better than DSLR cameras.
Compact cameras
Compact cameras are lightweight, portable and easy to use. They don't require that you spend time setting up apertures and shutter speeds; simply point and shoot for great results.
DSLR cameras: A summary
DSLR cameras are versatile: whatever your subject, a DSLR will deliver fantastic picture quality. Their interchangeable lenses mean you can alternate between styles to develop your photography skills, while their impressive storage and battery life mean you won't have to worry about cutting your days out short.
They're bulkier than mirrorless and compact cameras, so if you want a camera that's lightweight, a DSLR may not be for you. Still, DSLR cameras are a fantastic choice for both beginners and professionals, and are sure to help you develop as a photographer.
