What does continuous autofocus mean in Canon 90D?

Once the focus is closed, the camera's focusing system will continuously track the focus point, which is suitable for capturing moving people, animals, etc.

However, it is important to note that continuous focusing, there is no in-focus tone, and once it is out of focus, the shutter will also be released, and it may shoot out of focus**. For a single focus, there is not only a focus prompt sound, but also an in-focus shutter that is not released.

Focus mode, in different occasions, should be used rationally and understand its characteristics.

The so-called "continuous autofocus" seems to be easier to understand, in Nikon's parlance: "3D focusing".

Actually, to explain it in photographic terms, it's called: continuous servo autofocus.

The corresponding is single-shot servo autofocus.

In other words, when using single-shot servo AF, you can only focus once when you press the shutter halfway.

If the camera moves at this point, it will be out of focus.

Continuous servo autofocus, on the other hand, can always focus, keep focusing, and never lose focus.

This is very useful for photographing moving objects, such as birds.

That's what "continuous autofocus" in 90D means.

The so-called continuous autofocus means that even if you move the subject after you focus, it will still continue to track and intersect, for example, if you want to shoot a wild goose, then a big swallow, and take pictures while flying you, then you must use continuous autofocus.

Literally, the camera will continue to autofocus on the subject after it is turned on, which is useful when shooting moving objects.

1. At present, all DSLR cameras have "single autofocus" and "continuous autofocus"."functions; It's not just the Canon 90D;

2. Normally, the "continuous autofocus" function is used to shoot moving objects, such as running people or birds, or airplanes taking off, etc.;

3. Because of the above situation, the focal length of the subject is constantly changing;

4. If you shoot still life (such as landscape) or people in the landscape, the focal length is fixed, so it is generally set to "autofocus" to "off";

5. Generally speaking, except for professional sports photographers or professional bird activity photographers, ordinary people do not use the "continuous autofocus" function.

6. Therefore, the default setting of all DSLR cameras is that "continuous autofocus" is off.

As far as the description is concerned, this asks. First of all, it is recommended that you go through the camera manual. This is the best introductory textbook. Not one of them!

Secondly, literally, multiple focuses. For example, when the subject changes, it automatically refocuses.

I don't know how to continue asking, satisfied.

It may be too late, but it's really wronged to see so many wrong answers.

Canon's continuous autofocus = "pre-focus", even if you don't press the shutter, he will also be autofocusing, it is highly recommended to turn it off, it costs electricity!

The Canon 80D can be digitally zoomed by cropping the frame. Since you need this digital zoom (that's what you call digital zoom) function, then, just turn it on. There is no doubt about this.

However, if you take a closer look at the pros and cons of digital zoom, you will find that there is actually no benefit to turning on this digital zoom function.

The so-called digital zoom is actually the ...... of cropping the pictureCutting off a part from the original ** to obtain a smaller ** is equivalent to a ...... elongated focal lengthThat's how digital zoom works.

However, the result of this digital zoom is to greatly reduce the resolution of **, once 100% of the picture is played, the bridge may not even cover the full screen, resulting in a ...... degradation of image quality

Therefore, this method of digital zoom is actually the least worthwhile way to use.

We use DSLR cameras like the 80D.

The fundamental purpose of making a film is to obtain high-quality ...... for the sake of talkingAnd this kind of digital zoom itself is a loss of image quality, which is more than worth the loss ......

So, if you need a telephoto effect, go for a telephoto lens. Let's ......

It's generally turned off, because digital zoom is actually to crop the picture and enlarge the center part, which can be done in post-processing, and now there are a lot of digital zoom algorithms that are more intelligent than those built into the camera.
