Ya... now have one of your clients run and see how well that adapted glass tracks

It's a really good system. Just needs native and I'm having issues with native right now.
I agree it needs native to get the utmost out of the AF system...but there is a huge photo world out there that does not need the utmost AF tracking. Eye- AF is simply amazing and allows you to make images that are extremely hard with traditional focus...but are quite easy with eye AF tracking.
I've been using both native and adapted glass and don't have any issues with AF or image quality. Don't know what your issues are, but I'd look at either your camera has a problem or more likely you have something setup wrong.
