Yes, but they are using lenses made for the GH5 m4/3 format, so a standard zoom is 12-35mm which is the same as a 24-70mm zoom on a Full Frame camera.
For the Canon R camera with it's 4K 1.67x crop you would need to use a 14-42mm lens to get the same view as a 24-70mm lens on a Full Frame camera.
You might want to give your film a look through grading, to make appear less like a "family vacation" video. Here's a frame from "Saving Private Ryan" (1998) that uses a bleach bypass grade to make it feel "grittier" : http://cinematicpaintings.com/post/126030090653/saving-private-ryan-1998
Finally another high quality V90 SDXC card brand enters the market. ( Panasonic V90 cards are great but they cost a fortune )
Can't wait to try this new card out.
The GH5s camera takes things even further. Here is my favorite short made with the GH5s and Fujinon cine lenses ( there's a company in England that adapts these lenses to the Micro 4/3 mount )

You should check out the camera reviews at the www.backscatter.com website that covers everything from GoPro action cameras to $40K underwater cine rigs. They are a dedicated underwater photography and video website.
The DOF difference between the GH5 and a Full Frame camera is 2 F-stops, so if you can shoot with a lens that is 2 F-stops faster than you would with a Full Frame camera the DOF is the SAME.
This is relatively easy to do with "normal" and telephoto lenses ( especially with GH5 speedbooster adapters ), but for some wide angle lenses you can only open up to f/1.4 on the GH5 which matches the DOF of f/2.8 on a Full Frame camera.
Generally I don't find the DOF difference to be that big of a deal for me, where being able to shoot 4K 10-bit 4:2:2 with the GH5 has been a big improvement over shooting 8-bit footage. ( color correcting for sh*tty fluorescent lights is not so bad now )
