... Sony A7, and the major turnoff for me was the price of the native lenses.
+1
exactly. Sony lens prices are way too high,. for what it is. Zeiss badge notwithstanding. And Fuji charges FF prices for APS-C only lenses. No way. Aside from the Canon UI and all the Canon gear I giot, lens pricing is the main reason I have not yet bought a Sony mirrorless system.
Sony got the bodies, Canon got the lenses ... and I am not going to mess around with metabones adapter.
I think this may the reason for the higher price of native FE mount lenses. It has to do with the higher R&D costs for the lenses, which are challenging to design as the Sigma CEO states.
Here is the latest inconvenience:

It shows the full frame mirrorless Leica SL with the 50mm f/1.4 Summicron, the Sony a7RII with the 90mm f/2.8 macro G, and the Canon 5DsR with the 50mm f/1.2 lens. I had to double check a couple of times to convince myself that the Leica 50mm Summicron really was that big and that no mistake had been made with lens choice.
The Leica SL full frame mirrorless mount diameter is wider than that of the FE mount (51mm vs. 46.1mm). This shows why Sony used an APS-C mount on their FF mirrorless model, because if you use a dedicated FF mount with dimensions more typical of a full frame mount like those of the Leica SL mount, it causes an even more massive blowout in the lens size! Now we understand the basis for the Sigma CEOs puzzlement when he said that "...the diameter [of the FE mount ] is very small and makes it difficult to design high quality FF lenses ... it almost looks like E-mount was designed for APS-C more than FF".
Sony simply had to put an APS-C lens mount into a full frame body, because otherwise a 50mm f/1.4 lens would have ended up the same size as a 90mm f/2.8 macro lens:

Here the Leica SL is shown with the 50mm f/1.4 Summicron, the Sony a7RII with the Zeiss 55mm f/1.8, and the Canon 5DSR with the Tamron 90mm f/2.8 lens.
Yet even after putting an APS-C mount onto a full frame body, Sony still failed to reign in the blow out in lens size on professional fast lenses as this comparison of 85mm f/1.4 lenses on the a7RII and the a99 shows:
The added difficulty in designing full frame lenses for an APS-C mount on a FF body explains why the roll out of lenses has been so slow and the resulting lenses more expensive. It explains the reluctance of Tamron and Sigma to make FE mount lenses, because they are concerned about the ability to recoup R&D cost.
