From what I got from you, Andrew and Emanuel, and from what I found on youtube, these are some low budget options:
-One Plus 7t Pro (video below- Thanks Emanuel for poiniting out- I didnt get that info at first sight)
-Mi 10 (Thanks Andrew, looks like a kewl device even without RAW video)
-LG G8s
-LGv50
-IQOO 5
-Poco X3 (this one would be a guess, from the other five phones above is footage floating around with supposely Raw clips recorded with the Motoion Cam App)
So friends, go ahead and research this interesting field. Cannot wait to see some footage. One thing I recognize, the first testers show some enjoyable footage, just like the pioneers back then with their first GH1, 5D2 footage. Some great little clips from these enthusiasts!
