i still have the a6000 here and the a7II , i have the helios - 44 on the a6000 in my bag and the Laowa 15mm f4 on the A7II and now the A7IV + SEL24105G as walk around , so i will still be using MF beside the AF .
I was running that Helios setup earlier at a festival and it was wonderful using the manual focus in such a lively location after using AF on a 35mm 1.8.
I've been looking at getting the a6700 to update, I was really on the fence of sticking with APS-C but I wouldn't mind it for video commercial jobs, especially with the vintage lenses or some consumer priced APS-C cine lenses like the Sirui ones
