Peri Paleracio (Club Ocellaris, Anilao) has kindly sent me a review of the Huawei underwater/cell phone housing with an added underwater lens, it may be of interest (1,2). It looks like it uses water proof lenses, if so, no ports are needed.
Apps provide the cell phone with a dive computer and with controls for the touch screen via buttons on one side of the housing; a vacuum leak detector is built into it. Let us await what the reviewers and early users have to say.
This seems to be a sampler of the miniaturization with quality that is becoming available, such as the Yongnuo camera (3) which uses the Canon EF lenses, but which still needs an UW housing with port.
This miniaturization might be considered part of the Spencer/Darwin Evolution of the UW Digital Camera (grouped in approximate but not chronologic order as the evolution has included much overlapping):
dSLR > 4/3's mirrorless > Mirrorless Full Frame > Point & Shoot, ie Olympus TG 1-5 > Cell Phone > UW Huawei (and we hope UW Yongnuo and others) > Smaller, lighter, tougher, easier to use cameras and housings, with the quality of a dSLR = Survival of the fittest.
