What lenses cannot be changed to focus on items closer or farther away?
Zoom lenses
Autofocus lenses
Fixed focus lenses
Stationary lenses
Fixed focus lenses are lenses for taking pictures that are used in cameras, that have a fixed focus, meaning that the focus on the image will be always located in the same spot and al of the other areas will look blurry to the sight, they can not change the focus to objects closer or further away, if you wich to focus something that is closer to the camera you need to back up witht eh camera and find the spot where the lens focuses on the object, so that would be the answer.
