Hi Bjorn_L,

Sorry that I forgot to mentioned, I have a BR-6 too. Controlling the aperture is not a problem to me.

I'm asking because I don't have a BR-6: Is that going to work with a G lens? I can see it working with a D lens where you set the aperture on the lens itself but (from pictures) I don't see an explicit aperture setting on the adapter.

Hi Leonard,

The BR-6 have a lock to open the aperture to it's maximum position. This allow us to operate the lens in either it's maximum or minimum aperture. To operate the lens in between, we need to try an error. Below is a link I found from youtube on how to use it.
