That's the answer right there. One advantage of mirrorless is no microfocus required. Now that you mention it, I had an SLT-A65v a while back that suffered from the same issues. I had to adjust microfocus for several lenses. Pain in the butt. The same thing can occur when using an LA-EA4 on a mirrorless due to the translucent mirror in the adapter. That mirror setup was one of the worst systems ever developed, AFAIC. You lose about a half stop of light due to the mirror. It put a lot of people of Sony.  

Nice, I'll look forward to seeing those pictures.  This issue I have is with all my lenses and since they were new.  I'm going to download a fucus chart and play around with micro focus adjustments next. I hope I find something there.  Thanks!

I’ll have access to a a68 in a couple weeks and post some shots to compare with the body settings. Part of it could be the lens aging too unless you’re having the same problem with multiple lenses. A lot of those 28-90/28-105s get softer with use and the worst are super glowy at the long end.
