I dont understand this, maybe i am just an idiot but when I put a lens on my camera, adjust the aperture to lets say f2.8, take the lens off and look at the diaphragm blades it is small, as if at f22. This is on all my lenses I have, the diaphragm blades when I look at them when the lens is off my camera is always at f22. I dont get it ???

I am using a D7000
