1 What is autofocus?

Autofocus is a system that uses sensors, motors, and algorithms to measure the distance between the camera and the subject, and then adjust the focus of the lens accordingly. The camera usually indicates when the focus is locked by a beep sound, a light, or a confirmation box in the viewfinder or on the screen. Depending on the camera model and settings, you can activate autofocus by half-pressing the shutter button, pressing a dedicated button, or touching the screen.

2 Autofocus modes

Autofocus modes are the options that determine how the camera focuses on the subject. There are two main types of autofocus modes: single-shot and continuous. Single-shot autofocus mode, also known as AF-S or One Shot, is suitable for stationary subjects, such as portraits, landscapes, or still life. In this mode, the camera locks the focus when you half-press the shutter button, and maintains it until you take the photo or release the button. Continuous autofocus mode, also known as AF-C or AI Servo, is suitable for moving subjects, such as sports, wildlife, or action. In this mode, the camera continuously tracks and adjusts the focus as the subject moves, as long as you keep the shutter button half-pressed or the dedicated button pressed.

Recent cameras have incorporated subject recognition to the Autofocus system. Human eyes, animal eyes and other subjects recognition AF are now expected features of some higher end cameras. So do read the manual ,watch utube vids to learn the camera settings to turn on/off these subjects detection/recognition features and fully take advantage of the AF system.

3 Autofocus areas

Autofocus areas are the options that determine which part of the frame the camera focuses on. There are three main types of autofocus areas: single-point, zone, and wide. Single-point autofocus area allows you to select a specific point in the frame, and the camera will focus on that point only. This gives you precise control over the focus, but it also requires you to align the point with your subject. Zone autofocus area allows you to select a group of points in the frame, and the camera will focus on the closest subject within that group. This gives you more flexibility over the focus, but it also means that the camera may not focus on what you want. Wide autofocus area allows the camera to use all the available points in the frame, and the camera will focus on the most prominent subject in the scene. This gives you the easiest way to focus, but it also means that you have the least control over the focus.

Many modern cameras now have "eye-detection autofocus" systems, which use advanced algorithms to identify and focus on the eyes in a portrait. Focusing on the eyes is essential for portrait photography. - The eyes are the windows to the soul, they convey emotion and connection. - In-focus eyes make a portrait feel more intimate and engaging. - A sharp focus on the eyes draws the viewer's attention to the subject's expression and creates a compelling image. - Blurry eyes can make the entire portrait look out of focus and unprofessional. - Accurate focus on the eyes ensures that your subject's eyes are in sharp focus and that the portrait looks polished and professional.

4 Tips and tricks for using autofocus

Using autofocus effectively requires some practice and experimentation, and there are several tips and tricks to help you improve your skills and take better photos. It's important to use the right autofocus mode and area for your subject and situation, such as single-shot mode and single-point area for a portrait, or continuous mode and zone area for a bird in flight. Additionally, you can use the focus lock feature to recompose your shot without changing the focus. The back-button focus feature can also be used to separate the focus and shutter functions, allowing you to switch between single-shot and continuous modes. If autofocus fails or is not accurate, manual focus can be used by adjusting the focus of the lens with the focus ring or the magnifier and focus peaking features.

Each lens has its minimum focus distance. The image would be blurry if the lens is too close to the subject . If a lens is not able to focus on a close up subject, try zooming out or taking a step back.
