Can someone explain these to me? I'm not sure I'm grasping the concept....
they place empty space between the camera sensor and the lens so that it can focus closer than it normally can, but then it cannot focus to infinity. i hope this helps, it could be said a little more in depth and technically more sound, but thats the gist.
