Sigma 17-70mm F2.8-4 C DC Macro OS HSM Lens

Has anybody had success with this lens on an a6300 or a6500?

I am about to send back a Sigma 17-70 C that I have a love hate relationship with.  The center sharpness is fantastic at all Focal lengths, but on my copy, the right side is unacceptable from the edge to about 20% in towards the center when shooting wider than about 30-35mm.  The left side is not tack sharp, but is acceptable.  I sent it to Sigma in NY and they said "all functions good"!    I'm pretty disappointed.  I may try another copy, but from what I have read, the 17-50 sounds like it may be better.

Yes, less reach, I know.  But, does it function reasonably well with the mc-11, which I already have.  It isn't Global Vision, so I don't know if recent updates to the adapter have helped. I read some old posts that weren't too positive.

Thanks

I
