    D850 newbie - struggling with sub dial control

    Hi all, I'm new to this forum and I've just got my new D850 and I'm in the process of setting it up.
    Generally a mixture of mind blown and excited with all the controls avaliable but one stumbling block I'm up against just now is when I rotate the sub dial nothing happens. Specifically I am in Manual mode with a manual focus lens attached and I'm trying to adjust the aperture with the sub dial and nothing happens. I've checked the aperture isn't locked and I'm sure its something 'simple' to fix, but for now I'm stuck.
    Many thanks in advance for any help!

    There are two sub dials.

    If it a manual focus lens that has the aperture ring on the lens, be sure the aperture is locked at the smallest aperture (f/22 or whatever). If the lens isn't set to the smallest aperture, you might see ERR in the top display.

    Do you know if it is an AI lens or a lens that might have been AI modified?
