Why is it said that wind has a great impact on macro photography?

Haha, what typeboy said is not entirely correct.

In macro photography, the focal length of the lens is different, and the minimum shooting distance is also different. For example, Nikon's 60 macro, the minimum shooting distance is, but this distance is not the distance from the subject to the lens, but the distance between the subject and the image. To put it bluntly, it is the distance to the CCD.

The imaging ratio mentioned by 14441680, are there any macro lenses now that have a 1:1 ratio? Entry-level macros are all 1:1. Nikon's 60mm, Komei's and Sony's 50mm are all entry-level.

Generally speaking, the maximum aperture of macro lenses is 2.8, and Tamron’s 180 is 3 or more. But when actually shooting macro, because the imaging distance is short, the depth of field is very shallow, especially when the ratio is 1:1. Therefore, when shooting macro, the aperture should be above 4, or even as high as 8. Only in this way can the front and rear depth of field be controllable.

Judging from the poster’s question, the poster wanted to take photos of flowers and plants outdoors.

If the wind blows, the imaging ratio reaches 1:1, that is to say, if the subject shakes by 1mm, the image will shift by 1mm on the CCD. The original author calculated by himself, how big an impact will this have?
