Thanks @Eloi for your suggestions.
We are actively working to improve our cables, cable design methods, customer communication on cables, and our image sensor flexes. It's a task we take seriously and want to improve upon.
However, it is doubtful we can use ZIF style connectors for our platforms or be able to use COTS ZIF/FFC ribbon cables. They are the least vibe/shock tolerant of any connector class which require a lot of mechanical backing support to stay latched and engaged (and it must be movable to allow insertion and removal), thus adding weight, complexity, and size to the drone.
All of our image sensor flexes are also high-tech flex circuit assemblies, with power routing, specific ground plane control, EMI shielding, and high-speed impedance control, neither of which can be obtained from COTS FFC parts.
Hope that partly explains why we do not normally use FFC/ZIF parts.
