How to Turn off Autofocus on Canon Rebel T7
The Canon autofocus system is good, maybe even one of the best. But there are times when it may not be idle. Often, this is the case if you would want to compose a scene differently and alter where the point of focus should be.
Many times, this is the case when the camera is on a tripod where you cannot pre-focus and recompose before shooting. To fix this issue, you will have to manually focus the lens.
If you are dealing with an 18-55m kit lens, you are required to slide the switch at the base of the lens from the AF to MF setting. From here, turn the focus ring to focus. Moreover, you will see the MF displayed on the shooting display of the LCD screen, it means that you are utilizing manual focus mode.
How Does the AF Work in a DSLR or a Mirrorless Camera?
If you own a modern EOS DSLR, it is important to note that it comes with two different AF systems. One of these systems is applicable when the images are composed in the viewfinder, while the other one is used in live view mode or video mode
Mirrorless cameras are designed to work in the capacity of live view mode all the time and hence have only one AF system.
Anytime you are using the viewfinder in a DSLR, the main reflex mirror reflects light to the viewfinder. The sub-mirror, located behind the main mirror, reflects some of the light into a dedicated autofocus sensor.
When in live view or video mode, the main mirror tends to lift up out of the optical path so the imaging sensor receives light at all times, and not only during exposure. In this mode, DSLRs use the imaging sensor to gather autofocusing data.
Whenever the viewfinder is in use, EOS DSLRs employ highly sensitive line sensors for autofocus ranging. These sensors are located at the base of the camera.
What Are the Different Autofocus Modes?
Most of the EOS cameras in the market offer two different autofocusing modes, while some have three. While the end result is that the camera lens automatically focuses, it would be best to set the mode to suit the subject.
One-shot AF
This AF mode best suits subjects that stay in one place as you take your photograph. The focus is locked with the first pressure on the shutter button. Also, one-shot AF is recommended if you do not know which mode to use.
Therefore, it is basically a general-purpose setting to suit most of the subjects. There will be a green focus confirmation signal in the viewfinder to notify you that you have achieved focus as well as an in-focus beeper.
In one-shot AF mode, the camera will not allow you to fully depress the shutter button until the subject is in focus. This means that you can only take a picture if the camera is able to focus.
AI Servo AF
This AF mode is designed for fast-moving objects. The camera works to calculate the exact location of the subject at the time the shutter fires and then focuses the lens accordingly. This model is designed to continually check the focus and re-focus the lens each time until the moment of exposure. It is therefore suitable for photographing moving subjects.
AI Focus AF
This mode, available only in a few cameras, can switch between one-shot AF and AI Servo AF depending on the movement of the subject. It is up to the camera to decide. The camera can detect the movement of the subject by taking several AF readings while the shutter button is partially pressed.
