Tip: Use the Canon G12’s built-in lens, which has a maximum aperture of f/2.8, or consider investing in a faster lens.
Increase the ISO
Increasing the ISO will make the camera’s sensor more sensitive to light, allowing it to focus more easily in low-light conditions. However, be careful not to increase the ISO too much, as this can introduce noise and grain in the image.
Tip: Use the camera’s Auto ISO feature, which automatically adjusts the ISO based on the scene and lighting conditions.
Use a Flash or External Light Source
A flash or external light source can provide additional light, making it easier to focus in low-light conditions.
Tip: Use the Canon G12’s built-in flash or consider investing in an external flash unit.
Focusing on Moving Subjects
Capturing sharp focus on moving subjects can be challenging, but there are several techniques you can use to increase your chances of success:
Use Continuous AF
Continuous AF is designed for tracking fast-moving subjects. This mode will help you maintain focus on your subject as it moves across the frame.
Tip: Use the camera’s AI Servo AF mode, which is designed for tracking fast-moving subjects.
Use a Faster Shutter Speed
A faster shutter speed will help freeze the action and reduce motion blur, making it easier to focus on moving subjects.
Tip: Use a shutter speed of at least 1/1000th of a second to freeze the action.
Anticipate the Action
Anticipating the action and focusing on the point where the subject will be, rather than where it is, can help you capture sharp focus on moving subjects.
Tip: Use the camera’s predictive focus feature, which uses advanced algorithms to predict the subject’s movement and focus accordingly.

What is the Auto Focus (AF) feature in Canon G12, and how does it work?
The Auto Focus (AF) feature in Canon G12 is a camera setting that helps to quickly and accurately focus on a subject. When the AF mode is enabled, the camera uses its built-in sensor to detect the subject and adjust the lens to achieve optimal focus. This feature is particularly useful when shooting moving subjects or in low-light conditions.
In the Canon G12, you can choose from several AF modes, including Face Detection,_object tracking, and manual focus point selection. To use the AF feature, simply set the camera to the desired mode, half-press the shutter button to activate the focus, and wait for the camera to confirm focus lock before taking the shot. By mastering the AF feature, you can achieve sharp, stunning images with ease.
What is the difference between One-Shot AF and Servo AF, and when should I use each?
One-Shot AF is a focus mode that locks focus on a stationary subject when the shutter button is half-pressed. Once focus is achieved, the camera maintains that focus setting until the shot is taken. This mode is ideal for capturing stationary subjects, such as landscapes, portraits, or still-life images. Servo AF, on the other hand, is a continuous focus mode that tracks moving subjects, adjusting focus as the subject moves.
When to use One-Shot AF: Use One-Shot AF when shooting stationary subjects or when you need to recompose the shot after focus has been achieved. When to use Servo AF: Use Servo AF when shooting moving subjects, such as sports, wildlife, or street photography. Servo AF can help ensure that your subject remains in sharp focus, even as it moves rapidly.
