Thanks Tim.
Well, I did a search here and saw the issues about the battery replacement issues, so primarily around things like that. I have a slight concern about the repair support, but it looks like there's still at least one place in the US that handles them.
Good advice about the AFD lenses, I didn't realize that. I'm still trying to get a good picture in my mind about the whole system. I know that some lenses are MF only, some AF, etc.
Other than that, maybe handling issues, maybe quirks with the different viewfinders, etc.
