MAVLInk cameras for orthomosaics and photogrammetry that will fit on a 6 inch quad for under $300?

Looking for recommendations for a small cheap camera that will fit on a 6 inch quad and be easy to set up with Ardupilot and be operated in missions.

The primary purpose will be to photography the ground for creating orthomosaics.

This will be my first time hooking up a non-FPV style camera and so ease of use with Ardupilot and Mission Planner is a consideration.

All other recommendations I have found on this forum link to discontinued or very expensive cameras, so if anyone can make other recommendations that would be very helpful.

Thanks in advance.
