Sorryyyy just wanted to have a better camera. You could at least... you know... advise us what our alternatives are? I mean we do love the rom. Just that we would want some features added.
Sony camera, which is a bloated monster, won't give you any better quality. You lose camera quality when you unlock bootloader, because you lose a few proprietary algorithms, which Sony refuses to provide for open source community. So, even if you port the original camera, that won't improve anything. That's the trade off for having a debloated custom rom.
My personal choice for camera is this: https://f-droid.org/repository/browse/?fdfilter=open+camera&fdid=net.sourceforge.opencamera
