CP+ 2016: A look inside the G Master lenses at the Sony booth It says that the new 24-70 2.8 might be the sharpest and maybe even the fastest focusing lens of its kind that they've ever tested. (Though of course, that's just their impression...no studio tests yet.) My question is, if there will always be a lag in an electronic viewfinder, how would they ever be able to tell? It seems like they're closing the gap with the a6300, and hopefully that technology will trickle up to the next full frame, but it can't ever be perfect, right? Or will the camera focus and track better than the photographer will be able to? You select the subject, start a burst, and trust the camera to focus faster than it can show you what it's focusing on? That gives a whole new definition to the term "spray and pray..." Don't get me wrong, I'm super excited about these lenses, it just seems odd to have a lens more capable than the camera can utilize. Maybe it's future proofing?
