OM-D EM-5 EVF and aperture question

[n5jrn]

When manually focusing using the EVF, is the lens aperture while focusing set:

1. Automatically by the camera body, regardless of the exposure mode,
2. At whatever aperture will be used for taking the shot,
3. At the widest possible aperture (i.e. like what a conventional SLR does),
4. It depends on how the camera is configured, or
5. Something else entirely.

I've heard the Fuji X-Pro 1 has the nasty property of being (1) above. I would hope that the OM-D, which obviously is inspired by an SLR, would be either (3) or (4), and if (4) probably with (3) as the default option. But I haven't been able to find anything on the Internet which says just what it does.

I havent tried it with native lenses, but I assume it would be point 1.

Using my E-M5 with the grip, I assigned aperture preview to one of the base FN buttons. In manual focus mode I am able to preview the aperture and focus. Using the focus assist function (magnify) I am able to preview after activating the magnify, but not the other way around (magnify after preview). This is of course with M43 lenses. I will probably assume the same for 43 lenses. So, I guess the answer is (3) by default, along with (4).

That's good news. I recently played with my Dad's M43 camera (whose EVF isn't as good as the one on the OM-D), and was pleasantly surprised by how much EVFs have improved in the past three or four years. It wasn't as good as an optical VF, but it was possible to manually focus with it with reasonable accuracy (in other words, probably good enough for my purposes).
