[QUOTE="J-see, post: 519351, member: 31330"] Take any lens and point her with the end towards a wall. Then shine a flashlight at the front element. You'll see her cast the light at the wall. Now draw a square inside the circle of light. If you divide that square into two parts, does that in any way affect the light hitting the now smaller part? [/QUOTE]
