What is the best focusing method for shooting landscape photos?

Landscapes are generally in focus at infinity. If it is really necessary, if the hyperfocal distance cannot meet the requirements, then the only option is post-production synthesis.

Focus is also called focus. A convex lens produces an image. For an object at infinity, its imaging position is at the focus.

There are relatively few opportunities to actually shoot infinity (such as shooting landscapes). Most of them are objects within a dozen meters of the lens. At this time, the imaging position is not at the focus, but before the focus. In order to take this kind of close-up image, the distance between the lens and the photosensitive element must be reduced. This can be achieved by moving the lens or the position of the photosensitive element. In practical applications, moving the lens assembly is the most convenient, so most lenses have a focusing function. .
