I think, it is using contrast detection AF. It is early form of focusing with live view and slow. My t3i was like that. It has bunch of modes to help (using OVF phase detect AF) with live view. Pany and Nikon uses same contrast detection AF. It improved a lot over the time. Based on your experience, looks like Canon also doing fine with contrast detect AF with 4k.C-A430 said:Why is no DPAF an issue? M50 is using phase detection AF in 4K, just as α6500. In 1080p it has DPAF, something no one has matched yet.ritholtz said:For me only thing missing is DPAF. I can live with the 4k crop. I have used crop (digital zoom) feature with my SL2. It gave me reach to shoot some stage play. Unfortunately there is no dpaf when this functionality used with SL2 as well.Talys said:I agree that no DPAF is a downer. But this is a $740 camera. I think it's fine in that context, because you must expect to bump into some limitations at that price.ritholtz said:Video seems to be good until they start moving camera. I think 1 to 1 pixel crop for 4k produces good quality for the targeted users. But no dpaf is a downer. I wish, they will solve one of this problem (crop or dpaf) at least instead of punishing users twice.
I would say the two downers are no Eye AF in AI Servo mode (I think) and no DPAF in 4k video mode.
But both would be good incentives to buy the next version up. Also, something to let Sony come in with a competitor at that price point -- as a6300/a6500 are much more expensive. And well, Nikon needs to get their act together for live view AF before they're part of that discussion.
Sony and Panasonic NEVER use DPAF. Am I missing something?
