I record a concert using the Sony a7III and Sony a7RIII. I use a couple of accessories like the SmallHD Focus and Rode Videomic Pro to help with the setup. I use a wide angle Sony 24-70 F4 for the wide shot, and I use the Sony 70-200 F2.8 GM OSS lens for the close-ups.
I use the Sony a7III, a7RIII, and a6000 for some sports shooting. I make some general comparisons over the image quality and features in this VLOG
