Lens opening is the second country on your camera.

If you change the lens opening by one stop, the light either doubles or decreases by half.

How many stops difference between f/4 and f/22?

The lens opening is getting smaller, so the amount of light will decrease.

f/4 to f/5.6

One Stop Less Light

f/5.6 to f/8

One Stop Less Light

f/8 to f/11

One Stop Less Light

f/11 to f/16 One Stop Less Light
f/16 to f/22 One Stop Less Light

By going from f/4 to f/22, there are five stops less light reaching the sensor.
