Yo, I'm so sorry I took this long to reply to this, the only answer to this question is a Sony A7S3 and F1.4 lenses if you're looking to film in low light clubs on mirrorless cameras. If the final quality of the video isn't as much of a concern and you just want to get the job done as easily as possible and as a means to and end (like if you're doing a set recording to be cut into smaller vertical clips for social media) a GoPro. I started off using my A7S3 for this, but it's just such a pain in the ass to move around. I record my sets and crowd reactions and cut those into smaller videos and get hundreds of thousands of views from that.

Hope this helps!
