The Panasonic GH5 Camera is an excellent camera for both hobbyists and professional videographers.
While the GH5 won't be a king for photography due to its small sensor size, it's a beast for video with 60 fps 4K, 180fps 1080p, 10-bit internal recording, great interface, In-body stabilization, and so on.
I come from the GH4, and the biggest upgrade for me was the IBIS and increased native ISO level.
Everyone who is into video will not regret this camera.
Very impressive camera. I particularly enjoy the GH5 thanks to its in-body stabilisation and 4K capabilities.
