A couple observations…
5

1) The 24–70mm isn't a great lens (in the corners) at 24mm & wider apertures but it's fine there once stopped down. I recommend f/11. IMO strongly negative reports are due to sample variation, general inexperience with 24–70 zooms or people making declarations about equipment they haven't actually used.

2) All my wider lenses, whether native FE (including the 24–70) or adapted, perform better in the corners on my A7r2 than my A7r. Not hugely but noticeably. Maybe throwing more photosites into the mix improves things, maybe the BSI tech helps with angle-of-incidence issues, maybe there's some smarter processing going on…or maybe it's some combo of the these. Whatever, I'll take it.
