I am just beginning to learn about the Sony system and deciding what equipment to get.
Do Batis lenses (used on the a6300 or the a7r2) focus at the the maximum aperture or at the shooting aperture? If Batis focuses at the shooting aperture, are there other lenses that focus wide open?
The more you can tell me about this issue, the more it will be helpful to me.

Thanks for the help with this issue.
I believe this depends on your "Live View Display" setting on your camera. If you turn this on, you will basically see what the exact image will be before you take the shot. So, if you set the aperture at f11 for example, the aperture will be closed up to f11 permanently. It will also (try to) focus at f11 this way. If you turn the "Live View Display" setting off, the camera will act the same way as a DSLR. It will show DoF and focus at max aperture, and only close the aperture after acquiring focus.

On the a6300, there is a setting under Live View Display for "setting effect on" or "setting effect off". Is this the setting you mean? I would assume this would affect the view through the EVF as well as on the lcd display?

This is the setting I mean, yes. I am pretty sure it effects both the EVS as the display...
I just tried it... If I turn off this setting (on my A7II) off, the aperture is wide open and only after acquiring focus it will close. If I turn this option on, it will just keep the aperture permanently on the chosen f-stop.
The electronic viewfinder in the mirrorless system is capable of making up for the light loss in the viewfinder. Under bright lighting conditions outdoors, for example, you wouldn't be able to tell the difference whether the aperture is stopped down or by how much. But if you do a session in a studio, you have to compose and AF under the modeling light only and then, the viewfinder or the monitor will get too dim and grainy. That's when you turn the Live View display to "off" and then the viewfinder would look bright again. Keep in mind that most studio sessions is done using studio flash units and the shooting aperture is fairly small, like f/5.6 to f/8 or something like that.
Composing or more appropriately if I say, focusing at the actual aperture has some advantageous. Some lenses, especially fast lenses, suffer from the so called "focus shift". I am not sure whether you are aware of the issue with Canon EF 50mm f/1.2 or not. You focus on the eye at f/1.2 and you take the picture at f/2 and when you look at the result, the eye is not in focus but the ear is. The focus plane shifts away from what you focus on. A little more dramatic example but you get the drift. That focus shift condition becomes a non-issue using mirrorless.
Two images from Mono Lake, California using Batis 18mm
Mark--does it behave differently under af-c than under af-s? Under af-c, if you have acquired and then lost focus, does the lens open up again or does it stay shut down?

Not taken with a Sony or Batis, but showing my happy friend using his new Batis 25/2 on a7R2 at the Huntington Gardens in Pasadena. He's jumped in with both feet, moving up from a Nikon D200 and average/consumer lenses.

Thanks, Chris! I know both of them personally. They do their own design and they make their own costumes by themselves. It takes them months to do that; their costumes are very intricate and detailed.
