Camera Focus Chart

Nailing focus in photography starts with discovering the different ways you can focus using your lens and camera

If you are having a hard time, you can use the chart below to test your camera's autofocus and the measurements on your lenses. It could help solve any chromatic distortions on your gear.

What is Focus? What is Back Focus? 

Focus is the operation that enables you to enhance and emphasize a subject by making it stand out sharply against its surroundings. 

The correct focus allows you to build an emotional relationship with your pictures.

However, poor focusing can create blurry images and draw your viewers' attention away from your subject.  

Well, how does focus work?

After setting your gear to shoot, the lens allows light rays into the camera. The light hits the autofocus sensor that determines whether or not the subject appears in focus.

If the scene isn't as sharp, the sensor directs the autofocus motor to move the lens elements until the subject is the focal point. 

An error known as the back focus might occur during focusing. This error is when your subject gets out of focus, and instead, the sharp focus falls past it. 

It mostly occurs if you use a fast aperture lens or if the photographer imprecisely places the focal point to focus on the background.

How Do You Know if You're Front or Back Focused?

Front focusing occurs when sharpness lands in front of where you focused instead of your subject. On the other hand, back focusing occurs if focus falls behind your target subject. 

How to Focus a Camera

Correct focusing creates tack-sharp images that impact both the photographer and the viewers. However, the correct focus is something that can be hard to achieve, especially for beginners.

So, does focus differ per camera? Yes, cameras have different hyperfocal distance and autofocus performance. The reason is, cameras have a varying depth of field, which is the area within a scene that is acceptably sharp.

Another thing that makes cameras differ in focus is the specific lens. The choice of a lens on your camera controls the broadness of the sharpness in a scene because lenses have different aperture values. A wide angle lens and prime lens will focus in different ways.

You can achieve focus by switching your lens to either manual or autofocus mode. Your choice depends on the scene, lighting, skills, and gear. 

Now, when the situation forces you to switch to manual, how do you focus the camera?

Here's how.

Twist the Focus Ring Until the Subject is Sharp 

After switching on the manual focus option, turn on the focus ring, and wait for different scene areas to come into focus. You'll see the effects of the scene coming in and out of focus through the viewfinder.

Switch Your Camera to Live View Mode

If you are using a DSLR camera, turn the Live View feature on to monitor your subject's sharpness. The Live View will allow you to preview the representation in the camera on the LCD screen.

Use the Magnifier Button to Zoom in Your Subject

After switching to Live View on a digital camera, you can zoom in to the focus scene by pressing the magnifier button. The arrows on your camera should help you move to the area of focus. 

Fine-tune Until the Subject is Sharp

Scan in and out of the shot in smaller movements until it does not get sharp further. 

Exit Back to Normal Before Taking the Shot 

Tap the magnifier button to return to normal mode before you snap.

Do's and Don'ts of Focusing Your Camera

Check out the tips below when focusing your camera:

Do's

Focus on the Eyes

The eyes are a fundamental aspect of any photoshoot. Viewers focus on a person's eyes when looking at a photo. Therefore, if the eyes are in focus, the picture will be a memorable one.

Ensure There is Enough Lighting

Low light conditions make focusing more difficult. When the lighting is sufficient, your subject will be visible enough for the camera to focus. You can use a light source to illuminate the shot if you are in a low light situation.

Steady Your Hands

Use both hands to hold your gadget and bring it closer to your body to avoid shaky arms. 

It is crucial to reduce unnecessary movements when focusing to allow your camera to focus on the target object. For a superior focus, consider using a tripod.

Don'ts

Don't Get Too Close to Your Subjects

You should create adequate focusing distance between the camera and your scene by moving back slightly or increasing your lens's focal length until the item is sharp. 

Don't Focus on The Wrong Subject

If you let your camera pick, it will focus on the closest item. Although it might work in some situations, it may fail when there are obstacles between the target item and the camera.

You can avoid this error by switching to manual focus when shooting, especially with a zoom lens.

Conclusion

Perfect focus separates outstanding photography from the merely average. Thorough knowledge of focus distance and techniques is necessary to take your skills to the next level.

It shouldn't be hard to achieve focus if you turn to a focus chart for help. You can also practice focus by applying the manual focus steps when shooting. 

People Also Ask

It is not uncommon for you to think that your gear might be faulty whenever pictures don't turn out sharp. However, most of the time, blurry snaps result from the mistakes you make during shooting. 

You can avoid such a setback by answers to some of the questions you might have about camera focusing. 

Where Should the Paper Be Placed Relative to the Lens to Get a Sharper Focus?

Your lens can hunt for focus on a paper to no success if you place it in a horizontal position before the camera. 

However, if you want a sharper focus, try turning the same paper sideways and focus the camera since the lens achieves focus more easily if objects are in vertical positions.

How Do I Make Sure My Camera is in Focus?

Keeping a camera in focus depends on the distance between the target object, the lens, and the image sensor. You can keep the camera in focus by adjusting the settings on the camera.

You can also physically move the camera closer or further away from the subject until you see a sharper image.

Do Professional Photographers Use Autofocus?

Autofocus is appealing because it does not require training or a deep understanding of lens calibrations.

However, some situations and scenes require familiarity and manual adjustments of the lenses. In such a case, professional photographers start with autofocus and switch to manual focus to adjust the modes to befit the target item and scene. 

Why Won't My Camera Focus?

If you are struggling with poor camera focus and are consistently front or back focusing, you could be ignoring several factors.

For instance, you got your lens calibration wrong, have a shallow depth, or your subject is always moving. You can also check and improve on your lighting and clean your camera lens contact

What is AF Test?

An AF test is the test you take to determine how fast and accurate your autofocus is. 

Comparing these two factors is easy because differences in autofocus speed and accuracy are significant between different cameras. The test includes phase detection, contrast detection, and measurements of ultrasound and infrared distances.

Hi, I’m Andy. I’ve been taking pictures for just about as long as I’ve been old enough to hold a camera. I studied photography in community college after high school but was encouraged to follow a career path that was more stable. I do gigs here and there on the side but never took the leap to focus my efforts full-time. When Pam reached out to me through a mutual friend, I jumped on the opportunity to be a writer. Favorite type of photography: macro and street.
