Camera gear is always going to be a game of evolution.
I have seen so many options to choose from when it comes to vlogging.
I have heard of gh5 first from casey neistat when he used to be active on social media. IMO, the GH5 wouldn't be first option when it comes to vlogging, but someone like you could use it considering all the features it has.
If you can, do go through Fujifilm xa5 and Gopro Hero7, since till date these have been my first choice when it comes to strictly vlogging.
