Well, I went and looked at the on-line lens review you referenced above, and there's a huge problem with the reviewer's understanding, obviously.
The on-line reviewer whose web page your looked at wrote, "color fringing is light and poses no problems, it looks better wide open than the Sony 50mm F/1.4 does, but from F/1.7 and down, it's about the same."
Uh...the tip-off is the use of the word "color fringing" to describe a fairly complicated optical problem. First, the term "color fringing" is not the correct term,and it totally,totally ignores longitudinal CA: for example, an amateur lens tester, like the guy who wrote the fan-review above uses the wrong term to describe CA, AND the lens you have exhibits the problem of Longitiudinal CA very,very badly.
Obviously, if some internet wannabe' lens "tester" shoots a flat chart, and everything is in-focus and on a single plane of focus, there will be very little longitudinal "color fringing",since everything on the exact plane of focus is good,longitudinally, but that does not address lateral CA. As your angled photo, with differing depths shows, there is very little lateral chromatic aberrration at the edges of the in-focus lettering, but there is a hint of latral CA around the in-focus letters. However, the lens exhibits positively HUGE amounts of longitudinal chromatic aberration. So, the on-line lens review the fellow did really is not what I'd call a reliable source of information.
So, basically, the internet lens fan who wrote the "review" used the wrong term to describe lateral CA, and ignored (probably through ignorance) the immense longitudial chromatic aberration the lens model exhibits. So, if you want a lens that is capable of doing the kind of shots you showed, you obviously need a lens that is much less prone to "LoCa" or "bokeh CA" at wide apertures. This type of bad bokeh CA is not a lens-to-lens defect; pretty much any lens of that same exact design and make will exhibit the same problem, so another copy of the 50/1.7 will have the same characteristic. This problem would be less-visible if the lens had been stopped down three stops or so, but then the bokeh would be different...
