This concept of using fluids to focus light has been around for some years. I think it has been applied to other applications in research but commercially implemented. So I think Philips's lens is the first example.

It works very well when it is in miniature like for those micro cameras in a phone. But really if applied to a DSLR, I wonder how much that lens is going to weigh with the fluid. In addition, how will the fluid perform when the camera gets shaken upside down and inside out vigorously. Dispersal of the two liquids can occur, causing the lens to fog and become useless until the fluids separate....
