Just to make sure I did the math right in my head, the Sony 35mm F2.8 FE has nearly the same DoF capabilities as a MFT 17.5mm at F1.4 right?
Basically around there, though I don't recall if its exactly f1.4 equiv.
I found the 35 FE to have very smooth transitions from in to out of focus, so its not a lens that produces a very shallow DoF look. The overall rendering is typically pretty smooth though, with just occasional nervousness on some subjects such as lots of trees, and a bit better at closer distances. Very sharp lens though, and simply fantastic across the frame stopped down.
Basically does about everything you'd want in a lens, ie; small size, great hood, AF, great optics, however, it doesn't really have much of a "wow" factor. It is in a way a bit "boring", as far as 35mm f2.8 images go, not really giving that different of overall look that you'd get from a fast 17mm or 23mm on m4/3, APS-C shot wide open, or for that matter most FF DSLR f2.8 zooms.
That is by no means a bad thing, and it does its job with a nice size, AF etc, but there isn't that unique DoF advantage over smaller formats you'd see more from a 35mm f2.0 or 35mm f1.4.
Lens like a 58/1.2 on the other hand gives quite an apparent difference in isolation with the same framing vs something like the 35/1.4 on APS-C or 25/1.4 on m43. Those are both great lens in their own right, but compose the same frame with them and then a fast 50 on the A7(r) and you do get a rather different overall look and way of rendering.
