What is a DSLR Camera?
DSLR stands for Digital Single Lens Reflex. In a DSLR camera, there is a mirror box and a pentaprism which allows you to get your optical viewfinder. When you take a picture, the mirror flips out of the way blocking the viewfinder, letting the light go through and exposing the centre or the film, and that is how a DSLR works.
What is a Mirrorless Camera?
In a mirrorless camera, there is no mirror, thus the name Mirrorless. Many smartphones have mirrorless cameras.
Size of the DSLR Camera vs the Mirrorless Camera
In terms of size, the DSLR Camera tends to be larger, thicker, heavier and takes up more space because it has a mirror box and a pentaprism inside. The mirrorless camera, on the other hand, is smaller, thinner and lighter. If you are out there shooting using a mirrorless camera, somebody may look at you and be like that camera is small and may conclude that you are not a professional photographer.
Is the Mirrorless Camera technology better than the DSLR Camera?
DSLR cameras have fewer electronics in them because they do not have an EVF(in-body stabilization) to stabilize your shots. Mirrorless cameras have a little more technology into them since they have the electronic viewfinder in them
Battery Life of DSLR Vs Mirrorless Cameras
Most mirrorless cameras do not have a great battery life compared to DSLRs. This is because in the DSLR you do not have to power up an electronic viewfinder, your sensor is not always on receiving a signal that has to put through the EVF.
The viewfinder of DSLR Vs Mirrorless Cameras
DSLRs have an optical viewfinder while mirrorless has an electronic viewfinder. The optical viewfinder is what you see through the lens while an electronic viewfinder you only see an electronic representation of what the sensor is seeing.
In terms of quality, the DSLR is better and therefore I want to conclude that the DSLR cameras are better than the mirrorless cameras since they are more comfortable, have longer battery life and they make a person look more professional.
