I'm curious if anyone has made this switch? I've really enjoyed the Z7, but find the AF tracking good, but not great. I also like the idea of Sony's native 1.4 glass and two card slots. However, I've used the Nikon for many paid jobs and it's great. So why switch? Mostly, for the above two primary reasons...2 cards and native 1.4 glass. Although, the card issue seems remote, it's best to have and not need it. Right? Having the extra resolution probably won't make any difference other than perhaps a hardware upgrade, but the extensive lenses in the Sony line up are impressive.
