A DSLR (Digital Single-Lens Reflex) camera is a digital camera that uses a mirror-and-prism system to reflect light from the lens into an optical viewfinder. When you press the shutter, the mirror flips up, letting light reach the image sensor. This mechanism delivers:
Accurate real-time optical viewing
Fast autofocus
Exceptional image quality

Why DSLRs Still Matter in 2025
Although mirrorless cameras continue to dominate the market, DSLRs remain popular for several reasons:
1. Optical Viewfinder (OVF) Advantage
Unlike electronic viewfinders, an OVF shows the scene exactly as it is—no lag, no digital interpretation.

Brands like Canon and Nikon have decades of DSLR lenses available—often at reduced prices in 2025.
5. Ideal for Beginners & Hobbyists
DSLRs are intuitive, ergonomic, and forgiving for first-time shooters.
How a DSLR Works (Easy Explanation)
1. Light enters through the lens
2. Mirror reflects light upward
3. Pentaprism flips the image into a correct orientation
4. Optical viewfinder displays the scene
5. Shutter opens → mirror flips up
6. Sensor captures the image
This classic mechanism is what makes DSLRs unique in today’s digital camera landscape.
