Hi @Lukk,
Sorry about the late answer and thanks for your message 
We’re using these cameras for Reachy equipped with motorised zooms and lenses. The lenses are of different size but it is mostly for an aesthetic reason. Because of the motorised zooms, we can get between 65° to 125° of FOV.
You can take a look at the head’s CAD file if you want to see the different parts.
The cameras can deliver 1080p at 30FPS but because we integrated the streaming in Reachy’s ROS environment, we are currently working with a resolution of 480p at 30FPS and it is still enough to use the robot in teleoperation.
We are currently working on better solutions to handle the camera streaming.
Hope this answers all your questions!
Cheers
