Hello tcs, and welcome to the Camera Labs forum!
You've certainly read Gordon's review of this lens. Another professional review
came almost to the same conclusion: "the build quality is somewhat disappointing and optically it is also something of a mixed bag" (copyright Klaus Schroiff). There is also a very revealing shot showing very prominent CAs. As this occured not against bright sky but within the structure of a building I would not underestimate the problem of color fringing!
