Camera Focus Points Explained: A Beginners’ Guide

Camera Focus Points Explained: A Beginners’ Guide

There’s a lot to consider when it comes to focus points on your camera – how many there are, what type they are, and how they work with autofocus modes and AF area modes. In this article, we’ll break it all down for you so that you can make the most of your camera’s focus features.

First, we’ll explore what focus points and AF area modes are and how they work together. Then we will look at the types of focus points in different camera models and discuss which you should choose to get the best performance out of your camera.

Focus Points: What Are They?

The autofocus system on a camera is made up of many components. Two important parts are the focus points and the AF area modes. The focus points tell your camera where to look to find areas of contrast in which to establish an accurate focus plane, while the AF area modes change how that plane is established.

Let’s take a deeper look at how these work together:

The Focus Points – Your camera will have one to 49 focus points that it can use. These are positioned in your viewfinder, either clustered together or spread out, depending on the camera model you have. The number of focus points is typically stated somewhere on your camera.

Focus Points and AF Area Modes

You may see an icon in your viewfinder with a box, brackets, or even a single dot in it. If you see this, your camera is using the AF area mode that corresponds to it.

Let’s take a look at what each of these symbols means:

Single Point – This focus point is ideal for subjects that are in the same part of the frame most of the time, such as a person’s head or a small animal. You will select this focus point by using the joystick, cross keys, or touchscreen to move it around the frame.

Cluster – This focus mode is good for when you want to track a moving subject. The camera will use all of the focus points in the cluster to try and keep the subject in focus.

Wide – This mode is good for landscapes or scenes with a lot of space in the frame. The camera will use all of the focus points to establish the focus plane.

3D Tracking – This mode is similar to cluster, but it will continue to track the subject even if it moves out of the frame.

Auto Area – This mode is for when you want the camera to select a focus point on its own. It is using all of the focus points in selecting this point. You can change which focus point it selects by half-pressing and holding down your shutter button so the camera focuses on your subject, then moving the selected AF area mode away from Auto Area.

Now that you know what these symbols mean, let’s take a look at how they work together:

You are photographing a stationary subject – If your subject is stationary, you will want to use a single focus point. This will ensure that the camera focuses on what you want it to.

You are photographing a moving subject – If your subject is moving, you will want to use a cluster or wide focus area mode. This will allow the camera to track the subject as it moves.

You are photographing a scene with multiple subjects – If you are photographing a scene with multiple subjects, you will want to use the Auto Area focus mode. This will allow the camera to determine which subject you want to focus on. Unfortunately, the camera doesn’t always choose the right subject, so you may need to fine tune it with your selected single or cluster focusing point.

What are AF Modes?

AF modes allow you to control how your camera establishes an accurate focus plane. There are three different autofocus modes that come on most cameras: Single Shot, Continuous Shooting, and AI Servo. Let’s take a look at what each of these modes do:

Single Shot – This mode is the simplest mode to use. When you press your shutter button halfway down, the camera will focus on your subject and then take the picture. If your subject moves after the camera has focused, it will not be in focus in the picture.

Continuous Shooting – This mode is good for when you want to take pictures of a moving subject. The camera will continually take pictures as long as you hold down your shutter button. If your subject moves after the camera has focused, at least one of the pictures will be in focus.

AI Servo – This mode is similar to Continuous Shooting, but it will track your subject after it has focused on it. If the distance between the camera and the subject changes too much, you may need to use exposure compensation to adjust your exposure settings.

If you are having trouble taking pictures of stationary or moving subjects, try switching your camera to one of these focus modes.

Limitations of Auto Focus

No autofocus system works perfectly all the time, so there are some situations in which your camera may have trouble focusing on what you want it to. Here are three ways that you can try to fix this problem:

Limit Depth of Field – When you want to focus on a specific subject and blur everything else in the frame, you can use a large aperture setting to limit the depth of field. This will make it easier for your camera to focus on what you want it to.

Manually Focus – If your camera is having trouble autofocusing on your subject, you can try to manually focus on it. To do this, half-press and hold down your shutter button and then rotate the focus ring on your lens until the subject is in focus.

Use a Tripod – A tripod can help you take sharp pictures even when your camera is having trouble autofocusing. This is because it keeps the camera stable and prevents it from moving around.

How can I Customize my Camera’s Focus Points?

Most cameras allow you to customize the focus points that are available to you. This means that you can select which focus points you want to use, and then hide the ones that you don’t want to use. To customize your camera’s focus points, follow these steps:

  1. Press the Menu button on your camera
  2. Use the arrow keys to navigate to the Shooting Menu
  3. Use the down arrow key to select AF Point Selection
  4. Use the right and left arrows to select which focus points you want to use
  5. Use the up and down arrows to select which focus points you want to hide
  6. Press the OK button to save your changes

Now, when you go to take pictures, only the focus points that you have selected will be available to you. This can be helpful if you are trying to avoid accidentally focusing on the wrong part of the scene.

How do I Choose my Focus Point?

There are many different factors that go into choosing which focus point you should use. Since each camera is different, there’s no one-size-fits-all answer for this question. Here are a few of the most common factors behind choosing your focal point:

Subject Alignment – If your main subject is already centered in the frame, you might want to keep it that way by focusing on the middle of the frame. On the other hand, if you want your main subject to be off-center, you should focus one or two points away from where your subject is located.

Subject Movement – If your subject is moving, consider switching to Continuous Shooting mode instead of Single Shot mode. This will help you to capture more pictures of your subject, even if it is moving around.

Background Details – If you want to focus on the background details instead of the subject, you should use a large aperture setting to create a shallow depth of field. This will blur the background and make it easier for your camera to focus on what you want it to.

Where are the Focus Points Located?

Different cameras have different types of focus points. While there are some similarities between models, most cameras use one of four types of focus points:

Type 1 – These focus points consist of a single dot in the center of your viewfinder. They function like crosshairs and make it easy to find your subject.

Type 2 – These focus points are arranged in a cross pattern, like the letter “plus”. They make it easy to place your subject off-center and achieve an artistic effect.

Type 3 – These focus points consist of an outer ring that covers almost all of the viewfinder. They function like larger versions of type 1 focus points.

Type 4 – These focus points are very small and located in the corners of your viewfinder. They function like type 2 focus points.

Where would I use each one?

You can think of types 1 through 3 as being more appropriate for different situations, while type 4 is most useful when you want to cover a large area with your focus point.

Type 1 – These focus points are best for when you want to place your subject in the center of the frame. They make it easy to keep your subject in focus, and they’re perfect for portraits or landscapes.

Type 2 – These focus points are great for when you want to place your subject off-center. They’re perfect for capturing action shots or creating an artistic effect.

Type 3 – These focus points are best for when you want to focus on the background details instead of the subject. They’re perfect for portraits or landscapes.

Type 4 – These focus points are great for when you want to cover a large area with your focus point. They’re perfect for sports photography or any other time that you need to cover more space.

How does my camera choose which focus point to use?

Most cameras use a combination of the focus points that you have selected and previously used. This means that your camera is trying to find the best possible focal point for your current situation, but it’s not always choosing the focus point that you want it to. If this is a problem for you, there are a few things that you can do:

Select the focus point that you want your camera to use. This can be done with the buttons on your camera or through the menu system.

Disable automatic focusing and use manual focusing instead. This will allow you to choose the focal point that you want your camera to use.

If your camera has a Tracking Mode, use it to keep your subject in focus even if it’s moving around. This will help you to capture more pictures of your subject, even if it’s moving around.

Focus Points: Standard Versus Cross-Type

Most focus points are either standard or cross-type. Standard focus points are the most common type, and they work by measuring the contrast between the subject and the background. Cross-type focus points are more accurate, and they work by measuring both the contrast and the phase of light.

Which is better?

There is no clear answer, as both standard and cross-type focus points have their pros and cons. Standard focus points are more common, so they’re usually easier to find. Cross-type focus points are more accurate, but they can be harder to use in certain situations.

Focus Points and AF Area Modes

AF Area Modes

Your camera’s AF Area Mode determines what your focus point will be used for. There are four different AF Area Modes:

  • Single Point AF – This mode uses a single focus point to focus on your subject.
  • Dynamic Area AF – This mode uses a group of focus points to track your subject.
  • Cluster AF – This mode uses all of your camera’s focus points to track your subject.
  • Auto Selection AF – This mode chooses which of the above modes to use depending on the situation.

Which is best?

As with standard versus cross-type focus points, there isn’t a clear winner here either. Each AF Area Mode has its advantages and disadvantages, so you’ll need to decide which one is best for your needs.

In general, the Single Point AF and Dynamic Area AF modes are the most versatile, while the Cluster AF and Auto Selection AF modes are more suited for specific situations.

Shooting Still Subjects: The Focus and Recompose Method

When you’re shooting a still subject, it’s often best to use the Single Point AF or Dynamic Area AF modes. This will allow you to focus on your subject and recompose your shot without having to worry about changing the focus point.

How do I use it?

To use the focus and recompose method, follow these steps:

  1. Select the Single Point AF or Dynamic Area AF mode.
  2. Frame your shot so that your subject is in the center of the frame.
  3. Focus on your subject and take the picture.
  4. Recompose your shot and take the picture.

How well does it work?

The focus and recompose method works best when you’re shooting a still subject. It’s not as accurate when your subject is moving, and it can be difficult to use if your subject is close to the edge of the frame.

Shooting Moving Subjects: The AF Tracking Method

When you’re shooting a moving subject, it’s often best to use the Dynamic Area AF or Cluster AF modes. This will allow you to keep your subject in focus as it moves across the frame.

How do I use it?

To use the tracking focus method, follow these steps:

  1. Select the Dynamic Area AF or Cluster AF mode.
  2. Frame your shot so that your subject is in the center of the frame.
  3. Focus on your subject and take the picture.
  4. As your subject moves across the frame, keep it in focus by moving the focus point with the arrow keys on your camera.
  5. Take the picture.

How well does it work?

The tracking focus method works best when you’re shooting a moving subject. It’s not as accurate when your subject is stationary, and it can be difficult to use if your subject is far from the edge of the frame.

Conclusion

Understanding how your focus points work is essential for getting the most out of your camera. By choosing the right focus point and using the right AF Area Mode, you can capture amazing photos with ease. So experiment with different combinations and find what works best for you. Just remember to have fun and be creative!
