from Luca, aka spaceKoala cloudynights so starting from S30 pro, in (linux)firmware, devicetree DTB , the main (tele) 1/1.2" 8 MP camera module is software described(hardware abstraction) as below: which uses register = <0x30> reset-gpios = <0xa5 0x16 0x00) so in software side, whichever camera module that uses same register address, same reset-gpio address ( and formats) etc, can be used in S30 pro main camera. so the compatible options can be : SmartSens SC485SL (4MP) spec in 2024 SmartSens SC880SL (8MP) spec in 2023 OmniVision OS08B10 spec in 2021 so, maybe we are just not aware of that. this is same case in S50 pro details here compatible camera modules: SmartSens SC880SL OmniVision OS08B10 ( of course sony 585 is also included, but it uses different register addresses etc) from cloudynights post Seestar Pro's not sourcing their "585" sensors from Sony? milleniumfalcon here in Cloud...
