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?

photos mostly taken with manual lenses on Ricoh GXR M, Sony NEX5N, Pentax K-x and *istDs:

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?

Manual lenses have no electrical interaction with the body at all. The body doesn't even know there's a lens attached.

I think you must mean something else by "manual lens." What lens are you actually using?

For instance, the manual lens I just used on my camera is a 1970's Canon FD 55/1.2 SSC Aspherical attached using a plain aluminum tube adapter. This lens original coupled aperture information to the Canon bodies it was made for through an aperture lever, a stop down lever, and a max aperture pin. Only the stop down lever connects to anything in the adapter, and that's just to allow the lens to be stopped down when the aperture ring is turned. Nothing in the lens or in adapter couples to anything in the A7 body.
