🔍 How DSLR and Mirrorless Cameras Work: Key Operational Differences


Video: DSLR vs MIRRORLESS. Know THIS before you switch!








Let’s get technical but keep it fun. Understanding how these cameras operate is crucial to grasping their strengths and weaknesses.

DSLR Operation

  • Light enters through the lens and hits a mirror angled at 45 degrees inside the camera.
  • The mirror reflects light up into a pentaprism (or pentamirror), which directs it to the optical viewfinder.
  • When you press the shutter, the mirror flips up, exposing the sensor to light and capturing the image.
  • This mechanical action produces the iconic DSLR “click” sound and causes the viewfinder to black out momentarily.

Mirrorless Operation

  • Light passes directly through the lens to the image sensor without any mirror in the way.
  • The sensor sends a live feed to an electronic viewfinder (EVF) or the rear LCD screen.
  • No mirror means quieter operation and faster continuous shooting since there’s no mechanical movement blocking the sensor.
  • The EVF shows you exactly what the sensor sees — a “what you see is what you get” experience.

Operational Pros & Cons Table

Feature DSLR Mirrorless
Viewfinder Type Optical (real-time, no lag) Electronic (live preview, some lag)
Shutter Mechanism Mechanical mirror flips up Electronic shutter options
Camera Size & Weight Bulkier due to mirror & prism More compact and lightweight
Noise Level Audible shutter click Quieter or silent shutter options
Battery Usage Longer (no EVF power draw) Shorter (EVF/LCD consumes power)

🎯 Autofocus Showdown: DSLR vs Mirrorless Precision and Speed


Video: What is the difference between a DSLR and a MIRRORLESS camera!?








Autofocus (AF) is where the rubber meets the road. Whether you’re shooting wildlife, sports, or portraits, fast and accurate AF can make or break your shot.

DSLR Autofocus

  • Uses a dedicated phase-detection AF sensor located inside the camera body.
  • When you half-press the shutter, the mirror directs some light to this AF sensor.
  • Phase detection excels at tracking moving subjects and predicting focus shifts.
  • However, AF performance can degrade in Live View mode since it relies on contrast detection there.

Mirrorless Autofocus

  • Relies on on-sensor phase detection pixels (like Canon’s Dual Pixel CMOS AF or Sony’s Fast Hybrid AF).
  • Every pixel can assist in focusing, enabling faster and more precise AF across a wider area.
  • Mirrorless cameras often include eye-tracking and subject recognition AI, boosting focus accuracy on faces and animals.
  • Continuous AF during video is smoother and more reliable.

Real-World Experience

Our team at Camera Brands™ has tested the Canon EOS R6 (mirrorless) against the Canon EOS 90D (DSLR). The R6’s autofocus locks on moving subjects faster and tracks them more reliably, especially in low light. But the 90D still holds its own with robust AF in bright conditions.

Autofocus Comparison Table

Aspect DSLR Autofocus Mirrorless Autofocus
Speed Fast with dedicated AF sensor Faster with on-sensor phase detection
Accuracy High, especially in good light Very high, enhanced by AI features
Low-Light Performance Good, but varies by model Often better due to sensor-based AF
Video Autofocus Limited, slower in Live View Smooth, continuous, and accurate
