I recently shot this cover song and music video in 8K RAW on the R5C with a Great Joy 1.8x Anamorphic (50mm). My daughter sings here and I recorded the music, so I was occupied with a lot of things aside from the camera. Having said that, the camera performs really well for what it is and is a great addition for those who already own Canon glass. It's not going to replace a proper cinema camera in terms of the best DR or latitude, but it is an amazing tool and the in-camera anamorphic de-squeeze is a priceless feature. The video is uploaded in 8K so choose that for best quality:
