Trollman said that the A7 gives live view DOF preview. I own an A7R and I can't find any reference to DOF in the manual.

So how do we get DOF preview in the A7/R cameras?

You can turn on Live View Display which is in settings 2, but even with this on, from my observations it appears that the aperture opens to some extent, though it seems not fully, while focusing, so the DOF portrayal will not be accurate until focus is achieved.

However from what I have observed, even with Live View Display turned off, although the aperture seems to fully open during focusing, once focus has been achieved then it appears to shut down to your selected value, so at this point, with respect to DOF, what you see should be what you get. However you will not see the brightness of the exposure realistically portrayed with Live View Display turned off.

How does the aperture open or close at all on the manual lens in question?

When using FE lenses, have you observed the aperture opening or closing during viewing? I'm curious if it's actually doing this, or if it's the EVF compensating. I've been assuming it's the EVF trying to give constant output.
