What do you mean by enlarging the lens?

I want to explain some professional words you mentioned in a popular way.

Zoom-that is, you can make the picture bigger and smaller.

Focal length-is the size of the viewing angle that can be seen. The greater the focal length, the closer the feeling, the smaller the focal length and the farther the feeling.

Telescopic lens-refers to the lens can be hidden in the fuselage when not taking pictures, and can be extended when taking pictures.

Digital zoom-Contrary to optical zoom, it only enlarges the picture at the expense of pixels. That is to say, the picture is enlarged, but it is blurred.

Optical zoom-enlarges the picture by changing the position of the lens in the lens. In other words, if you enlarge the picture, the picture will not be blurred.

Wide-angle lens-a lens with a relatively small focal length, that is to say, it can see a relatively large range, but it feels far away. Usually used to shoot big scenes.

Telephoto lens-Compared with wide-angle lens, the visual range becomes shorter but the viewing angle becomes smaller, which is equivalent to seeing things through a telescope.

Focusing is the process of making the picture clear.

Zoom-that is, the process of making the picture farther or closer.

The camera doesn't have the best function, it depends on what function you need. I don't know what you want to shoot and how much you plan to spend, and I dare not recommend it to you. Generally speaking, the card machine is easy to carry, but the imaging effect is average and the zoom factor will not be great. A camera with a long focal length is generally large and inconvenient to carry, but its imaging is OK and it can be zoomed at a large magnification. Be sure to choose one with anti-shake function. SLR cameras have the best imaging and the largest volume, and need to be equipped with various lenses, which is very expensive.

Ok, that's all, I hope it will help you! ! !
