Zoom is to shoot pictures in different ranges by switching lenses with different focal lengths, so it is called zoom, which can widen and shoot large scenes, or zoom out to shoot distant subjects. This is a simple understanding.

Multiply and focal length calculation

I believe that friends who are not familiar with the concept of photography will not know why the photos taken should be marked with numbers such as 0.5X 13MM, 1X 26MM and 2X 52MM. Here is a brief explanation of these contents.

26MM means that when you use a Quan Huafu SLR camera and use the focal length of a 26MM lens, you can get a picture within the range shown in the following figure, while 1X means iPhone 1 1 take this lens as the standard. (The difference between each photo is seen from the surroundings, mainly the difference between enlargement and reduction, and the surroundings have the effect of being "cut". )

26 mm shooting effect

0.5X 13MM represents this picture, which is equivalent to the picture that can be shot by a full-frame SLR camera with a lens focal length of 13MM. The smaller the focal length of the lens, the wider the shooting range. Meanwhile, the front 0.5X stands for (1.0x26mm) x 0.5 = (0.5x13mm).
