Aperture value doesn't change with manual lens attached

Aperture priority (A) exposure mode is not applicable with a MF lens, since aperture cannot be set with the dials on the A7. M and S modes are very usable, on the other hand, along with manual or automatic ISO.

great summary Miki!

just...A mode works very well, also with manual ISO or auto ISO, only difference is that aperture is set on the lens, not on the camera

So, you have to set the aperture on the lens, and then also set the same aperture on the camera?

No. Only on the lens. You can't set it on the camera for manual lenses.

But in A mode, the top dial on the back (that sets the aperture) still rotates and changes the value of the aperture.

Isn't that value that the camera takes into account to compute the exposure?

actually, when you have a manual lens attached and camera set to A-mode, neither of the dials do anything.  You should see a flashing F-- in the viewfinder/LCD.  Exposure should be computed based on the actual aperture setting on your lens.  If you are using a legacy lens with a smart adapter (only available for Canon EF and Contax G, I think), then you will be able to set aperture on the camera and this can have some impact on exposure , at least with the Contax G smart adapter, but that is an entirely different thread discussion.
