I can't think of any reason for using adapters on Sony cameras really ...

The Zeiss 16-35mm f/4 OSS is pretty good in the ultra-wide zoom segment for instance. And beyond that is the Sony 12-24/4 and the Sigma 14-24mm f/2.8

It does seem like a lot of Sony lenses get less than spectacular reviews. 

I'm not that interested in using an adapter really. I thought it was interesting the Tokina, at least in the US, is actually sold paired with a Sigma adapter for a very good price. Their solution to not having a UW for the Sony? 

The Zeiss 16-35/4 OSS does look interesting and covers the main range I'm interested in. Does OSS work with the 5-axis IS in the A7RII?

Sony isn't exactly vocal about the existence of sync/dual IS. 
At least I've never seen any table with related f-stop gains. 
Therefore I wouldn't place any bets on this.

The only real disappointment, as far as lenses are concerned, is the Zeiss 24-70mm f/4 in my book - although it's probably fine on 24mp sensors. The 50/1.8 is also soso but then it's cheap. And the 28-70mm f/3.5-5.6 OSS is crap.

The majority of Sony's APS-C lenses are ... bleh.

However, the Sony G lenses are pretty much all very good and reasonably priced. The GMs are great but too expensive IMHO.

I'd suggest to go hold, handle and operate a A7R II first, to see if you not dislike how it operates (menus, controls) and such. It may be "cheap", but it must suit you besides a now low price, too.

I've criticized the shape of Sony cameras quite often in the past but the controls and the menu system are fine really.

Honestly, I don't get the whining about the menu system. There are actually TWO - like in most mirrorless cameras.
The main menu may be not optimal - but I couldn't care less really. I access the main menu pretty much just once following the purchase and thereafter only for sensor cleaning/firmware upgrades/card formatting. During field sessions, I use the quick menu (AF/MF modes, fps/timer, ISO, WB, DR etc.)  and that's pretty much enough except for exotic use cases. The quick menu system is perfectly Ok. Maybe it's different for video - I can't really comment on that one - but for photography I have no real complaints there. But, of course, that's just me.

So yes, it makes sense to handle the camera to make sure that you can live with the grip and the edgy design - and check whether the AF is good enough for you.

Thanks for the input. 

I'm not really worried about the menus. People say the same thing about the olys. I tend to set it and forget it. Most of it anyway. My concern is more the glass I can get.

I'm not giving up on mft by any means. That will still be my grab and go system. My thought for the Sony is a hi-res landscape camera. Thus why I'm looking at UWs. Therefore, I'm not really worried about shape. 

Likewise with AF. I'm sure the latest is better, and next generation will be even better. In real use, regardless of reviewers comments,  I'm surprised how few (next to none) out of focus captures I get with the PenF. It seemed an improvement to me compared to the Canon's I had owned.
