The terms infinity focus and focus to infinity are commonly used in photography articles and tutorials. But let’s get one point out of the way: even the most experienced photographers don’t know precisely what they mean! So, let’s start with How To Set Canon Zoom Lens To Infinity?

How To Set Canon Zoom Lens To Infinity?

Turn your focus ring to the infinity sign to set your camera’s lens to infinity focus. Not all kit lenses have this choice. Numerous autofocus lenses lack an infinity focus setting. The focus ring on older lenses is more likely to have an infinity setting.

What Is Infinity Focus?

It is possible to use an infinity-focus lens to capture images at a distance so far away from the camera sensor that all of the light rays entering the lens are functionally parallel to one another. In doing so, you eliminate the blur and the resulting halo effect, making the entire image more sharply focused.

If you use infinity focus, you won’t get an exceptionally crisp picture because nothing is out of focus. To put it another way, infinity focus can be likened to producing an enormous depth of field. Even though it may seem like it, the infinity setting does not deliver perfect focus at the infinity’s distance.

Because the infinity focus point is located at a distance from the camera, a subject close to the lens will not focus. In front of the camera, this is known as the hyperfocal range. Multiple factors, including the camera’s crop factor, affect hyperfocal distance. Everything up to and including the point of infinite concentration must be clearly in focus when using this technique.

How To Set Your Camera To Infinity Focus?

Your camera lens’s focus ring can be changed to infinity focus by turning it to the infinity symbol (). This feature isn’t available on every kit lens. Infinity focus is not a standard feature on many autofocus lenses. It is more common to find an infinity setting on older lenses.

The infinity symbol, as shown below, must be reached by rotating the lens focus ring clockwise or counterclockwise, as is the case with lenses that have distance scales. It’s just over the white line and to the right of the 20-foot mark. At the focal point of a lens, known as the image plane, an object at infinity will appear as a single picture.

How To Focus To Infinity?

Even if you’re a beginner in photography, you can learn how to focus to infinity, even if you’ve never done it before. Learning to infinity focus is made more difficult because each lens has a somewhat different method. With the instructions below, you can easily focus to infinity as soon as you have lenses capable of infinity-focussing.

  1. Determine whether or not your lens can focus to infinity. Your lens’s focus rings—the portions you can twist to change your focal length should have at least two of them.
  2. When using a manual lens, check for the infinity sign on the lens to switch to manual focus (MF).
  3. Completely turn the smaller focus ring right. To achieve infinity focus, turn it to the left until you can see the indicator on the left-hand side of the screen.
  4. See what you wish to capture by peering through the camera’s eyepiece. Adjust the giant focus ring without adjusting the smaller focus ring until the subject’s outline is well defined in the viewfinder. A lack of focus may necessitate some physical adjustments, such as moving closer or further away from your subject matter.
  5. Has the problem persisted? Make use of a lower aperture to get the most out of your camera’s depth of focus (This may be particularly critical while photographing landscapes to avoid hazy foreground objects).
  6. Set a slower speed to compensate for a smaller aperture, as less light will reach your camera’s sensor.
  7. To decrease camera shake at these slower exposure times, a remote shutter release can be used in addition to the tripod.

When Should Infinity Focus Be Used?

It’s time to apply infinity focusing if you want distant items to appear sharp and clear! This is an excellent tool with mountains or other natural objects that may be kilometers distant as subjects in your landscape photography shots. Even if your subject is

thousands of miles away, your final image will be incredibly crisp since you set your camera to infinity focus on purpose. To get the most OK photos when photographing astral figures in the night sky, such as the sun and moon or even the Milky Way, utilize infinity focus. Infinity focusing will ensure that these magnificent subjects remain sharp and focused on your final images.

How Do I Set My Autofocus To Infinity?

Turn the focus ring to the infinity sign. This will put the lens at infinity focus. However, this feature is not included in all kit lenses. The infinity focus setting is not standard on autofocus lenses. The focus ring on older lenses is more likely to have an infinity setting.


Using the focus-to-infinity approach while photographing distant things, particularly at night, is a simple process once you get your head around the concept. It doesn’t necessitate much practice; all you need is a firm grasp of your gear.

You’ll be able to know How to set the canon zoom lens to infinity to capture far-off objects with pinpoint accuracy once you’ve identified the infinite focus point for each of your lenses. That’s all we have on How To Set Canon Zoom Lens To Infinity?

Frequently Asked Questions

What does the infinity symbol mean on a camera or lens?

At a distance so far that the light rays emitted by the subject matter are precisely parallel that your camera’s resolution limit cannot tell them apart from other perfectly parallel rays of light, your lens is said to be focused at infinity.

In terms of camera lenses, how far is infinity?

“An object is regarded to be at an infinity location when its proximity from the camera is 200 times the focal length of the lens,” says Steve Simmons in Using the View Camera. So for a 50mm lens, it would be 10,000 mm or 10 meters (30 feet.)

Is it possible to verify infinite focus?

The position at which the line segment of the [graphic] mark is matched with the distance indication on the distance scale is known as infinity at an average temperature. As you turn the focusing ring, glance through the viewfinder to see what you’re focusing on.

Is it possible to adjust a zoom lens’s focus?

A single micro-adjustment setting is typically available for all zoom positions on most cameras. Even though Reikan FoCal cannot compensate for cameras that do not support multiple micro-adjustment values, calibrating a zoom lens nevertheless yields superior results to those of an uncalibrated zoom.
