What camera to buy


I bought a few prime lenses for my Canon T6i. Found out later that they work better with full frame cameras. Cinecom.net praise the Panasonic Lumix GH5 Body for serious film making but I fear my already purchased lenses won’t work cause they are canon. Is there a Canon model equivalent to the Panasonic Lumix GH5 Body?
Can you recommend me a camera that will do both photography and filmography? Please and thank you in advance!
