Via this machine-translated blog entry is an interesting look at a product from Nikon, the Media Port UP300x. It’s a set of headphones outfitted with a eyepiece complete with a LCOS screen at 640×480 pixels, built-in media storage, and is intended for use as a PMP-type device. But it also offers a video input, and some enterprising individuals have hooked it up to the Nikon D90 DSLR for use with the LiveView and video recording functions. Is this the future of filmmaking?
