The above CA can be corrected with a click in ACR so a non issue in any normal shooting situation.
I know that and I have been doing that but it has an impact.
I could even live with that but I also did not see a noticeable IQ difference.
So the main point that remains is the build, extra DoF and the creative possibilities.
Not enough to justify the invesment right now.
Just from my perspective of course.
