For beginners. . It is common to take pictures with your camera on your back and sometimes forget to take off the lens cover. This is mainly because novices take care of the camera and wear it when something happens. In fact, if there is a UV mirror on the camera lens, there is generally no dust.

02

A special mode is used:

At present, there are many modes on SLR cameras, such as digital cameras, many automatic modes and many manual modes, which require manual adjustment of data. There are also some modes that are used to shoot special subjects, and sometimes they can't focus because of the wrong shooting mode (such as B-door mode).

03

Use manual focus:

In addition to the mode, the lens may also have problems, that is, the focus mode of the lens. There is a sliding dial ring on the lens, which allows the camera to change the focus mode. If it becomes manual, pressing the shutter cannot focus automatically (you need to turn the focus ring yourself). )

04

No memory card inserted:

If the camera just imported photos a few days ago and you forgot to put the memory card in it, you can't take photos (you can't enjoy taking photos by pressing the shutter), but many cameras can be set to take photos without the memory card (you can only take photos, but you can't save photos).

05

The shooting environment is too dark;

If you are in a dark (poor light, not enough) environment, when the camera can't recognize what you are shooting, you can't focus by pressing the shutter, even if you can't press it, you need light to take pictures.

06

Camera damage:

Another possibility is that there is something wrong with the camera and it can't focus. In many cases, it may be that the shutter button is wrong, or the focal length of the lens is damaged, which needs professional inspection.

07

What mode is better for beginners:

In order to prevent beginners from choosing the wrong shooting mode, which mode is better to start practicing? I suggest that the aperture is the best, and then you can try the automatic M mode. As for the landscape mode, it is similar to a digital camera. . Don't try.

08

When is it suitable for manual focusing?

There is also the choice of focusing mode. Many people will ask, since manual focusing is so troublesome, why design it? Of course it works. When we shoot something very fine, such as jewelry, it will actually be clearer than autofocus. Sometimes, we deliberately blur the photos. What do we do? It is also correct to shoot with manual focus.
