The Canon T6i, also known as the EOS 750D outside of North America, is a popular entry-level DSLR that has found its way into the hands of countless aspiring photographers. One of the most important features for any camera is its autofocus system. So, a burning question for many considering this camera is: Does the Canon T6i have Dual Pixel autofocus?
The Autofocus System Of The Canon T6i
The short answer is no, the Canon T6i does not have Dual Pixel CMOS AF. It’s crucial to understand what this means for the camera’s overall performance and in what situations this difference is most noticeable.
The Canon T6i relies on a hybrid autofocus system. This system blends phase-detection and contrast-detection autofocus technologies to achieve focus. In essence, it attempts to combine the speed of phase detection with the accuracy of contrast detection.
Phase-Detection Autofocus
Phase-detection AF is typically quicker at acquiring initial focus. It works by splitting incoming light into two images and analyzing their relative phase difference. This allows the camera to determine both the direction and the amount of lens adjustment needed to achieve sharp focus. The T6i uses a dedicated phase-detection AF sensor with 19 cross-type AF points positioned across the viewfinder area. These cross-type points are more sensitive than standard AF points and contribute to improved focusing speed and accuracy, especially in challenging lighting conditions or when tracking moving subjects. The 19-point system provides a decent coverage area, allowing you to select a focus point that aligns with your subject within the frame.
Contrast-Detection Autofocus
Contrast-detection AF, on the other hand, is generally more accurate but slower. It achieves focus by analyzing the contrast levels within the image. The camera adjusts the lens until the contrast reaches its peak, indicating the sharpest possible focus. Contrast detection is primarily used in Live View mode and when recording video on the T6i.
Dual Pixel CMOS AF: What It Is And Why It Matters
Dual Pixel CMOS AF is a more advanced autofocus technology developed by Canon. Let’s delve deeper into what it is and why it makes such a significant difference.
How Dual Pixel AF Works
Unlike traditional autofocus systems, Dual Pixel CMOS AF features a sensor where each pixel is divided into two separate photodiodes. These photodiodes can be read independently to perform phase-detection autofocus directly on the image sensor. This means a much larger portion of the sensor area is available for phase-detection, resulting in significantly faster and smoother focusing, particularly in Live View and video recording. This system greatly improves focus acquisition speed and tracking performance when compared to contrast-detection AF.
The Benefits Of Dual Pixel CMOS AF
The advantages of Dual Pixel CMOS AF are numerous:
- Faster Focus: It provides significantly quicker focus acquisition compared to contrast-detection AF.
- Smoother Transitions: Focus transitions are noticeably smoother and more natural, especially during video recording.
- Improved Subject Tracking: The system excels at tracking moving subjects, keeping them sharply in focus even as they move across the frame.
- Enhanced Low-Light Performance: Dual Pixel AF performs admirably in low-light conditions, allowing for reliable focusing even when light is scarce.
- More Responsive Live View: Using Live View for photography becomes a much more fluid and responsive experience.
Comparing The T6i’s Autofocus To Dual Pixel AF Systems
To further understand the absence of Dual Pixel AF in the Canon T6i, let’s compare its autofocus performance to cameras that do feature this technology.
Performance In Live View And Video
The most significant difference is apparent in Live View and video recording. On the T6i, Live View autofocus relies heavily on contrast detection, which can be slow and prone to hunting (the lens moving back and forth before locking focus). When recording video, the T6i’s autofocus can struggle to keep up with moving subjects, resulting in noticeable focus shifts and potentially distracting the viewer. Cameras with Dual Pixel AF, on the other hand, provide a much more responsive and reliable Live View and video autofocus experience. The focus is acquired quickly and smoothly, and subject tracking is significantly more effective.
Still Photography Performance
For still photography using the viewfinder, the difference is less pronounced. The T6i’s 19-point phase-detection system provides decent performance for capturing static subjects. However, when shooting in challenging conditions, such as low light or with fast-moving subjects, the limitations of the system become more apparent. Cameras with Dual Pixel AF can still offer benefits for still photography, particularly when using Live View or when shooting in situations where precise and reliable focus is critical.
Alternatives To The Canon T6i With Dual Pixel AF
If Dual Pixel CMOS AF is a must-have feature for you, consider some alternative Canon cameras:
- Canon EOS 80D: A significant upgrade over the T6i, offering Dual Pixel CMOS AF and a more advanced feature set.
- Canon EOS 77D: Another excellent option with Dual Pixel AF, offering a good balance of features and performance.
- Canon EOS M50: A mirrorless camera with Dual Pixel AF and a compact design.

Does The Canon T6i Actually Have Dual Pixel CMOS AF?
The Canon EOS T6i (also known as the EOS 750D) does not feature Dual Pixel CMOS AF. This autofocus technology, known for its smooth and accurate focusing in live view and video recording, was introduced in later Canon models. The T6i instead uses a hybrid autofocus system that combines phase-detection and contrast-detection AF, but it doesn’t have the advanced capabilities of Dual Pixel.
The absence of Dual Pixel AF means the T6i relies more on contrast-detection AF in live view and video, which can be slower and less precise compared to Dual Pixel AF. While still capable, focusing performance in these modes isn’t as refined as in models that incorporate Dual Pixel technology. This is a key difference to consider when comparing the T6i to newer Canon cameras.
What Kind Of Autofocus System Does The Canon T6i Use?
The Canon T6i utilizes a hybrid autofocus system that integrates both phase-detection and contrast-detection methods. The phase-detection AF is primarily used when shooting through the viewfinder, leveraging 19 all cross-type autofocus points spread across the frame. This allows for quick and accurate focusing, especially in well-lit conditions, when shooting still photography through the viewfinder.
However, in live view mode and during video recording, the T6i relies more heavily on contrast-detection AF. While it can still achieve focus, this method tends to be slower and can sometimes “hunt” for the correct focus point, which might be noticeable during video recording. The hybrid system provides adequate performance, but lacks the speed and smoothness of Canon’s Dual Pixel AF technology.
How Does The Autofocus Performance Of The Canon T6i Compare To Cameras With Dual Pixel AF?
Cameras equipped with Dual Pixel AF generally offer significantly faster and smoother autofocus performance compared to the Canon T6i. Dual Pixel AF allows for quicker and more precise focusing, particularly in live view and video modes, due to the way each pixel on the sensor is designed to detect phase differences. This results in smoother transitions and a more reliable tracking capability, particularly in moving subjects.
The T6i, relying on its hybrid contrast-detection AF in live view and video, tends to be slower and less decisive than cameras with Dual Pixel AF. Users might experience more instances of focus hunting, and the transitions between focus points are often less seamless. While the T6i is capable, the difference in AF speed and precision is noticeable, especially when recording video or photographing fast-moving subjects in live view.
Is The Autofocus Of The Canon T6i Good Enough For Shooting Video?
The autofocus on the Canon T6i is adequate for shooting video, but it’s not ideal for professional-level filmmaking. The hybrid autofocus system, primarily using contrast detection in video mode, can be prone to hunting for focus, particularly in low light or with challenging subjects. While it can achieve focus, the speed and smoothness of the transitions aren’t as refined as those found in cameras with Dual Pixel AF.
For casual video recording and vlogging, the T6i’s autofocus can be sufficient, but it requires careful monitoring and may necessitate manual focusing in some situations to ensure sharpness. Users who require precise and reliable autofocus for more demanding video projects may find the T6i’s capabilities limiting compared to newer cameras featuring Canon’s Dual Pixel CMOS AF technology.
What Autofocus Modes Are Available On The Canon T6i?
The Canon T6i offers several autofocus modes to suit various shooting scenarios. When using the viewfinder, you can choose between One-Shot AF (for stationary subjects), AI Servo AF (for tracking moving subjects), and AI Focus AF (which automatically switches between One-Shot and AI Servo). These options provide flexibility for capturing different types of photos effectively.
In live view mode, the available autofocus modes include Face Detection + Tracking AF, FlexiZone – Single AF (allowing you to select a single focus point), and Quick Mode (which temporarily flips the mirror down to use the phase detection AF system). While versatile, these modes can be slower and less refined compared to the autofocus performance when using the viewfinder due to the reliance on contrast-detection AF.
Does The Canon T6i Have Face Detection Autofocus?
Yes, the Canon T6i does offer face detection autofocus, specifically within its live view mode. When enabled, the camera can detect and prioritize faces within the frame, ensuring that they are sharply focused. This is particularly useful for portraits and group shots where the faces of the subjects are the most important elements.
The face detection feature on the T6i helps simplify the focusing process by automatically identifying and tracking faces as they move within the scene. However, it’s important to note that the performance of face detection AF is generally better in well-lit conditions. In lower light or with complex scenes, it may not be as accurate or reliable as in optimal conditions.
Can I Manually Focus The Canon T6i?
Absolutely, the Canon T6i allows for manual focusing. This is achieved by switching the lens to manual focus mode (MF) using the switch typically found on the lens barrel. Once in MF mode, you can rotate the focusing ring on the lens to adjust the focus manually until the image appears sharp in the viewfinder or on the live view screen.
Manual focusing can be particularly useful in situations where autofocus struggles, such as in low light, when shooting through obstacles, or when dealing with subjects that have low contrast. It provides the photographer with precise control over the focusing process, allowing for creative control and the ability to achieve focus that the autofocus system might miss.
