I had a similar issue with a previous version. Bill on the website gave me this advice:I very much like the fact, although limited to manual focus, that you can now focus with lens wide open and the aperture will close down only when pressing the shutter. So it works almost like a typical DSLR.
Sadly this feature isn't yet allowed when using AF which would be even better. For example, in studio while shooting with strobes, and focusing is done under dim modelling lights (eg. flash much more powerfull than ambient light).
Afaik Sony A1 allows this, atleast with some lenses.
I hope they could allow changing the fixed stepdown limit of f5.6 to larger aperture. Using f2.8 for AF would allow 4 times more light to sensor - can't see why it wouldn't be beneficial for focusing.
"Check Custom Setting D9-Show effects of Settings-Except When Using Flash
This was added in Version 3.00."
I can't see this in firmware 5 any longer however I have tested with a flash and as long as the flash is switched on, the viewfinder will brighten up enough for the camera to focus
