As a beginner photographer, understanding how to use autofocus on your Canon Rebel T5 can be a game-changer for capturing sharp, high-quality images. Autofocus is a powerful feature that helps you quickly and accurately focus on your subject, ensuring that your photos are crisp and clear. In this article, we’ll take you through a comprehensive guide on how to use autofocus on your Canon Rebel T5, covering the basics, different modes, and advanced techniques to help you take your photography skills to the next level.
Understanding Autofocus Basics
Before we dive into the nitty-gritty of using autofocus on your Canon Rebel T5, let’s cover some basic concepts.
Autofocus (AF) is a camera feature that uses sensors and lenses to automatically determine the focus distance between the camera and the subject. This process is controlled by the camera’s autofocus system, which consists of several components:
- AF Sensor: This is the component that measures the distance between the camera and the subject. The AF sensor is usually located near the lens mount.
- AF Algorithm: This is the software that processes the data from the AF sensor to determine the focus distance.
- AF Motor: This is the motor that moves the lens elements to achieve focus.
Types of Autofocus
There are two primary types of autofocus: Phase Detection and Contrast Detection.
Phase Detection Autofocus
Phase detection autofocus uses a dedicated sensor to measure the phase difference between light rays entering the camera through the lens. This method is fast and accurate, making it ideal for tracking moving subjects.
Contrast Detection Autofocus
Contrast detection autofocus uses the camera’s image sensor to analyze the contrast between different areas of the image. This method is more accurate but slower than phase detection autofocus.
Canon Rebel T5 Autofocus Modes
The Canon Rebel T5 offers several autofocus modes to cater to different shooting scenarios. Let’s explore each mode in detail:
One-Shot Autofocus (AF)
One-shot autofocus is the default mode on the Canon Rebel T5. In this mode, the camera focuses on the subject once and then locks the focus. This mode is suitable for capturing stationary subjects, such as landscapes, portraits, and still-life photography.
AI Servo Autofocus (AI)
AI Servo autofocus is ideal for capturing moving subjects, such as sports, wildlife, and action photography. In this mode, the camera continuously focuses on the subject as it moves, allowing you to track the subject’s movement.
AI Focus Autofocus (AI)
AI Focus autofocus is a hybrid mode that combines the benefits of One-Shot autofocus and AI Servo autofocus. This mode is useful when you’re unsure whether the subject will move or remain stationary.

What is Autofocus and How Does it Work?
Autofocus is a feature in your Canon Rebel T5 camera that allows it to automatically adjust the focus of your lens to ensure that your subject is sharp and clear. It works by using a combination of sensors and algorithms to detect the distance between the camera and the subject, and then adjust the lens elements to bring the subject into focus.
The camera uses a variety of autofocus modes to achieve this, including One-Shot AF, AI Servo AF, and Manual Focus. One-Shot AF is the default mode, which focuses on a stationary subject and locks the focus when the shutter button is pressed halfway. AI Servo AF is used for moving subjects, and continuously adjusts the focus as the subject moves. Manual Focus allows the user to manually adjust the focus using the lens ring.
What are the Different Autofocus Modes Available on the Canon Rebel T5?
The Canon Rebel T5 offers several autofocus modes, including One-Shot AF, AI Servo AF, and Manual Focus. One-Shot AF is the default mode, which focuses on a stationary subject and locks the focus when the shutter button is pressed halfway. AI Servo AF is used for moving subjects, and continuously adjusts the focus as the subject moves. Manual Focus allows the user to manually adjust the focus using the lens ring.
In addition to these modes, the camera also offers several autofocus area modes, including Single-point AF, Zone AF, and Automatic AF point selection. Single-point AF allows the user to select a single autofocus point from 9 available points.
