My first time playing around with a Canon 5d mark IV. Had the a6300 shooting behind the scenes:
Couple of things I learned:
1. Ewww, how did my jpeg become so ugly in the youtube cover view.
2. DPAF works great, but you may need to fiddle in the menus to stop it from seeking new focus after a face disappears (fast moving action isn't the best use for DPAF). Forwards / backwards moving objects + dpaf is awesome.
3. I was surprised by how much fun taking photos with it was. 7 fps (eventhough it's just one more than the 5d III) seems to increase responsiveness alot.
4. I'm still gonna stick with the 5dmarkIII + RAW video. 4k isn't really that interesting to me. Atleast not yet.
