The A6600 is made in China (the first of the A6xxx series to be made there). My A6000 for example is made in Thailand. I have no problem with this. As long as Sony is on top of quality control (and I am confident that they are) this makes no difference to me.
Reviewers sometimes complain about things that I am glad are the way they are.
One review was wishing that the body was more like the bigger A7R. For me that would kill this camera -- I want the compact "rangefinder" style body. If the A6600 became a big "professional" looking camera, I would be elsewhere.
Another reviewer apologizes mildly about the lack of popup flash, but ultimately agrees with me. He would never use it. I would never use it. Nobody who isn't simply desperate would ever use it, so be glad it isn't there. Rockwell on the other hand goes on at length about what a terrible thing it is that there is no built in flash. It takes all kinds to make a world.
The menu system is a maze. The wise suggestion is to put things you expect to use frequently in the "my menu" section that is provided for you. This sounds like excellent advice.
I am sort of used to the menu system from my years with the A6000. I don't like it, but I know what to expect and am actually happy that things have not been turned inside out and upside down.
I don't do video, at least not yet, so various complaints about video limitations are pretty much lost on me. Likewise burst shooting is something I have never cared about, but that is just me.
If you were starting from scratch with no investment in Sony lenses, you might want to consider the Fuji XT4 or XT3 as an alternative APS-C sensor camera. But I have no interest in reacquiring a collection of lenses, so I am sticking with Sony.
The mysterious S and Q position on the dial are apparently slow and quick movie modes.
