What Is a DSLR Camera?
DSLR stands for Digital Single-Lens Reflex. These cameras use a mirror mechanism that reflects light from the lens into an optical viewfinder.
When you press the shutter button:
- The mirror flips upward
- Light reaches the sensor
- The image is captured
Popular DSLR models include:
- Canon EOS 90D
- Nikon D850
- Canon Rebel Series
- Nikon D7500
For decades, DSLRs have been the preferred choice of professional photographers.
What Is a Mirrorless Camera?
Mirrorless cameras eliminate the mirror system entirely.
Instead of an optical viewfinder, they use:
- Electronic Viewfinders (EVF)
- LCD Screens
- Digital image previews
Popular mirrorless models include:
- Sony A7 IV
- Canon EOS R6 Mark II
- Nikon Z6 II
- Fujifilm X-T5
Mirrorless technology has become increasingly popular because of its compact design and advanced features.
