Reading the title, I thought: finally someone rooted/jailbroke sony cameras.

On Canon you can run Magic Lantern, an extensive mod that adds many features to Canon cameras.

Even Samsung N1 had SD Card loadable mods before they moved away from the camera market.

Rooting sony seems impossible, I never saw someone Working on it Since their Fullframe lineup launched.

The last two generations of Samsung NX cameras were built around Tizen Linux, and it was (and still is) easy to get a root shell on them. They still make great photos and you still can buy them used for a good price.

NX300/NX30/NX2000 had a read-only rootfs, but for NX500 and NX1 there was a persistent mod that extended camera functionality with a menu, and you can actually SSH into them and rsync your photos... while shooting!

Background: I've recently taken over maintenance of the NX-KS mod at https://github.com/ge0rg/nx-ks-mod

On some cameras, including the older firmwares for the current cameras, https://github.com/ma1co/Sony-PMCA-RE gives you a root shell.
