Sony A9ii RAW in Lightroom

People on this forum are just other users with very few adobe employees on it. You should make feature requests on https://feedback.photoshop.com where actual Adobe engineers are active. In this case you can count on them working on this one. Supporting a new camera is not a simple update. Adobe has to buy a copy of the camera (most camera makers do not send Adobe or other raw software developers prerelease versions so Adobe ends up in the same queue as everybody else preordering new cameras) when it becomes available. Reverse engineer the raw format (the camera makers do NOT publish specs for their raw formats and every camera release they change enough to have to make sure the changes are caught). They then shoot a large number of calibrated color charts with the camera under controlled lighting conditions and build standard and camera profiles from that (camera profiles are the profiles that mimic in camera jpegs). I have read that they will do this for more than one copy of the camera to make sure they are not calibrating for an outlier camera. This is a lot of manual work. Generally the profiles and raw file support end up in the next release but sometimes a release is already locked up before a camera appears and you have to wait two cycles. Minor Lightroom releases are about 2-3 months apart. So typically if you buy a camera on the day it came out you might have to wait a few months for Lightroom to support it. Here is data on how long it generally takes for a camera to get supported: https://community.adobe.com/t5/lightroom-classic/timing-of-lightroom-releases/td-p/8175418
