The reality is that Sony, compared to other lines, offers a great image with leading DR and log performance along with the best open lens mount in the industry. They’re pushing us to their fx like and I may be okay grabbing an fx30 for video work as it seems like a better buy than the alternatives when you consider quality, price, and lenses. I currently own an griiix and it’s pretty cool for most of my photo needs but have yet to try snapping my runners. Could always grab a used a6600 for some action shots of runners to pair with an fx30 for documentary stuff
