That was a nice idea to test, but as a G model doesn't have an aperture ring. I have just checked, and when I start to twist the lens, the diaphragm just starts to close.
I have tested it under different sources of light, and shutter speeds, so I would discard these variables.
And with that same particular behaviour in 2 different copies, I think it has to be a design issue.
Is not a major problem, if you know it and expect it. It's just strange.
As I said before, I haven't shot with too many different lenses in digital, so I couldn't say if this happens in more lenses. It's just the first time I see it.
I also have to note that, apart from this, I find the lens quite nice.
