Hey guys!

No matter what I try I can't seem to change my aperture on my a7s ii. I am using the metabones adapter, however, it is up to date with the latest firmware.

Anyone got any advice?

Do you mean the aperture does not change when you change it in camera? Or the aperture never changes even when taking photos? Metabones default "Green mode" is simulating Sony LAEA-3 adapter and it only closes aperture when taking a photo (like a SLR). If you want to aperture to change as soon as you change it on camera body (like native E-mount lenses), you can turn the Metabones into "Advance mode". Here is how http://www.metabones...power-save-mode.

I may have this same problem. In my case, the camera does not see the lens at all and displays f-- 

The problem is intermittent and sometimes everything works perfectly, with the camera being able to see the lens and change the aperture. 

I have had some luck with fiddling around with the WO/CF (mode) button on the adapter, but I can never figure out which mode I'm in and eventually the problem returns.
I have written to Metabones and they have offered to examine and test my adapter for the cost of shipping - but shipping is to Hong Kong. I'm in the middle of a project that I bought the lens and adapter specifically for, so I told them I had to limp through the work before I could send the adapter back.

Do you by any chance have a Tough E mount installed replacing the factory mount? When I installed one I had to screw it in pretty tight to get the contacts to touch.
Maybe try tightening your mount (the 4 screws) down just a touch, even if it's the factory mount.
