What Is Dual Pixel Autofocus?
Canon’s Dual Pixel Autofocus (DPAF) is a technology that dramatically improves autofocus speed and accuracy — especially in live view and video mode.
Unlike traditional contrast-detection systems, DPAF uses phase detection across every pixel on the sensor. This means each pixel is doing double duty: capturing light and assisting with focus.
The result?
- Faster subject tracking
- Smooth transitions during video
- Accurate focus without hunting
It’s particularly valuable for hybrid shooters — those capturing both stills and video — or anyone who uses Live View regularly.
Which Canon Cameras Have Dual Pixel Autofocus?
Not all Canon cameras have DPAF, but many recent ones do. Here are some notable models:
- DSLRs:
- Canon EOS 90D
- Canon EOS 77D
- Canon EOS Rebel SL2 / SL3
- Mirrorless R range:
- Canon EOS R, R5, R6, R7, R10
- Canon M50, M6 Mark II
- Cinema C line:
- Canon EOS C70
- Canon EOS R5 C
Tip: Always check your camera manual or Canon’s website for confirmation.
How It Works (Simply Explained)
Imagine each pixel split into two photodiodes. As light enters the lens, both halves detect phase difference. If both sides “see” the same image, the subject is in focus.
If not, the camera knows which direction and how far to move the focus — without guesswork.
Compared to contrast-based systems (which rack focus back and forth), DPAF is decisive, fluid, and reliable.
Why It’s Great for Still Photography
In stills mode, DPAF comes into play when using:
- Live View on a DSLR
- Touchscreen focus
Face and Eye Detection
You get:
- Fast focus acquisition
- Sharp eye focus in portraits
- Accurate results even at wide apertures (like f/1.4)
Tip: Use Eye AF on supported models for razor-sharp portraits — even with moving subjects.
Why It’s Brilliant for Video
Video autofocus has historically been shaky. Older systems constantly pulsed in and out, hunting for focus.
DPAF solves that. It delivers:
- Smooth, cinematic transitions between subjects
- Reliable face tracking (great for vlogging)
- Customisable speed and sensitivity settings
It allows filmmakers and content creators to focus on framing and storytelling, not fiddling with manual focus rings.
Best Settings for Video Autofocus on Canon
If your Canon camera supports it, head to:
AF Settings > Movie Servo AF
Adjust:
- AF Speed: Slower = cinematic pulls; Faster = vlog-style snapping
- Tracking Sensitivity: Stickier = stays locked on subject; Responsive = shifts focus quickly between subjects
Touch & Drag AF is also worth enabling — especially for those using flip-out screens.
Use Cases for DPAF in the Real World
Here’s where it shines:
- Portrait Photography: Eye AF locks onto the closest eye, even at shallow depth of field.
- Wedding/Events: Quiet, accurate focus with no lag in Live View.
- Wildlife/Action: Face tracking and object recognition for moving subjects.
- YouTube/Vlogging: Keeps your face in focus as you move without needing a crew.
- Interviews: Focus pulls between two subjects can be automated without touching the lens.
DPAF makes your camera smarter — and lets you work more intuitively.
Common Mistakes to Avoid
Even with great tech, a few things can trip you up:
- Shooting through glass or obstructions can confuse the system
- Low contrast scenes reduce focus confidence
- Bright backlighting can make subjects harder to track
- Wearing glasses or masks may affect Eye Detection
To solve these:
- Use AF Point Expansion for wider coverage
- Increase AF sensitivity
- Position your subject with strong contrast edges
Manual Focus Override
Many Canon lenses with DPAF support Full-Time Manual Override (FTM).
That means you can:
- Let the camera lock focus automatically
- Then fine-tune manually with the focus ring — even in AF mode
It’s perfect for tweaking focus during interviews, close-ups, or macro work.
Advanced Tips for Getting the Most from DPAF
Use Back Button Focus: Decouple focus from the shutter button for more control.
Switch to Single Point AF for product shots or static subjects.
Use Zone AF when shooting unpredictable motion (e.g. kids or pets).
Enable Focus Peaking (on mirrorless models) to visually confirm sharp areas — especially useful when blending AF and manual.
Pair with RF lenses (on EOS R systems) for the fastest focus response and best Eye AF performance.

Micro FAQ
Q: Is DPAF available in viewfinder mode?
No — it only works in Live View or when using the LCD/electronic viewfinder on mirrorless models.
Q: Is Eye AF the same as DPAF?
Eye AF is powered by DPAF, but they’re not the same. DPAF enables Eye AF and other focus features.
Q: Can I use DPAF with adapted lenses?
Yes, but performance depends on the adapter and lens. Native RF/EF lenses perform best.
Q: How do I know if DPAF is active?
When in Live View or video mode, you’ll notice smooth tracking — not the “hunting” you’d get with contrast detection.
Q: Is DPAF better than mirrorless competitors?
Many pros consider Canon’s DPAF among the best for video and hybrid use. It’s fast, natural, and very accurate.
Final Thoughts
Canon’s Dual Pixel Autofocus is one of the most useful autofocus systems available today — particularly if you shoot a mix of stills and video.
It gives you confidence, speed, and creative freedom — whether you’re photographing fast action or shooting an interview solo.
If you’re not already using it, take time to explore the settings, practice with moving subjects, and fine-tune your AF preferences. Once mastered, DPAF can become an invisible assistant — working behind the scenes to keep your images and footage sharp, every time.
