The optics were custom built for this camera, so we'll have to wait until someone actually dives one.
I'm really excited about the viewfinder optic. Sealux builds the GS Viewfinder for Subal, and we all know what that did for their housings...
I'm not certain that is the correct interpretation of the buoyancy spec, Ron. I'm actually thinking they set this up to be slightly positive (granted 1.9# pos w/ the flat port is a lot, but the fisheye and wide angle lenses are a lot more manageable), and when the battery pack for the lights is added it is neutral. I'm trying to get clarification on this.
The housing does come with a flip UR Pro Red Filter & Flip +3 Diopter as standard equipment.
They use Subtronic S6 connectors for their monitors, not wet connects like Amphibico. I'm sure whatever connector Amphibico uses now could be retrofit.
