17? $1 plastic phone lenses and 17? $3 phone sensors. It seems a clever & original design but I'm not sure who is going to pay $1,500 for a camera based on phone camera technology.
That should certainly ONLY depend on the quality and usability the gadget delivers.
Great many expensive consumer/hobbyist electronics etc are put together from penny parts, still people happily pay thousands and more. It is not no business of consumers to really know what the ex-works price of the gadget is. It is called supply and demand, desirability, usability etc.
Besides Zeiss has informed us, in connection with the high-Megapixel Nokia smart phone camera, that it is actually possible to make extremely high quality and cheap small plastic lenses, but not larger ones, and we all know how much large high quality lenses cost. So the lens might cost $1, but equals optically an Otus...
