But are the time limits there to protect from overheating or just to not hurt the GH5? In other words can you restart video all day without it overheating like the GH5?
I guess it depends with which Canon body you compare. The liveview cdaf from 60D, 5D3, 6D, etc will I guess be the same as bmpcc6k. The dpaf from 70D, 80D, 5D4, 6D2 will be way faster.
The biggest problem is there are only a few active developers with not enough time. They already found ways to upload code to new camera's (M50, 80D, 5D4, etc) and are waiting for other developers to port existing code to them. I think the problem is there isn't that much demand as before because now we have the BMPCC and such.
The Canon 24-105mm f/4.0 L lens just isn't a sharp lens. Bought my first one second hand and thought it was just too used because at 100% the image most of the time looked slight out of focus. Sold it and bought a new 24-105mm f/4.0 ii L and this one is even worse. Bought the Sigma 24-105mm f/4.0 and it is way sharper. The only good thing about the Canon is that it's weather proof when needed. Maybe for video still good, but for photography not sharp enough for professional use.
Looks like it does ?

The sigma 17-50 2.8 is a nice lens, find it better then the tamron one (had both). Went now for the sigma 18-35 1.8, but it is much more expensive and heavy.
I'm sure they are here to stay (certainly with pro's). Their new RF lens line-up shows what they are best at. Just hope they also release some affordable lenses for the not-pro's ? Video features will always be a pain with Canon in their mirrorless or dslr. Don't see they changing much in the future.
