Overall -- the 'preview experience is not great, at all
-- this should be picture-in-picture kind of view.
Where I can have multiple settings previewed in different windows simultaneously, so that I can decide quickly which setting to choose, or click to take a 2 pictures, one for each setting...
I do not do much video, because I could not really figure out how to control auto focus selectively (when I want certain things in focus, and certain things out of focus as I pan)
My 14yo Lumix bridge camera can do Bracketing and Exposure compensation with a button press. Every DLSR I have used can with no look buttons and dials as well. I don't know about the flash sync as I never used that. What cameras are you using that the above things require menu hunting?
The multiple settings preview thing sounds interesting but isn't something I can see using myself. The video autofocus stuff is another example of why I don't like photography cameras being repurposed as camcorders, although I read dual-pixel AF and its equivalents are quite good. No personal experience though as I have no video interest really.
