The Sony camera ecosystem is nowhere near as complete as the long-time major players but they are putting some very advanced and capable technology into peoples' hands. Whether they can create a confidence-inspiring product line with product and service longevity is another matter; so far I haven't been too impressed in this area so no Sony in my stockpile. That and I don't like how they fit in my hand.
The AF abilities of the a6300 are not to be dis'd tho, you really need to try the thing with some of their better native mount glass. It's impressive when you see what the image-processing is up to before you press the button fully. It's comparable to the high-res AF+metering system sensors on higher end Canon and Nikon gear but without the specialized sensor hardware. AND you get to see the real-time tracking in the display.
The image drawing of their new G series lenses is nothing to snub either; high resolution and very smooth bokeh. The majors would to well to up their performance here too. I'd love to use some of those new lenses on my Fuji bodies.
Why they chose lossy-compressed raw, that results in image artefacts, on otherwise excellent hardware is beyond me. Should be easily fixable with firmware changes tho.
As for average users, I think it was reasonably covered. I don't think many of the customers who'll buy these systems, especially the Sony, are likely to add too much to their kit and shooting capabilities very soon. Most will likely use the body with a kit lens or 2. I suspect the 80D buyers are more likely to buy extras in short order to expand their capabilities.
If anything, what Sony brings to the table is another set of increased performance features that established mfrs will have to respond to in some way, eventually. it's all good.
But I just bought another Olympus body instead; MFT system has a strong position in my toolbox.
