master-piece and Panasonic are teaming up again to unveil the second version of their wearable camera project. Their initial release last year saw a Webcam Backpack that integrated a digital camera mounted on the shoulder straps. However, this year's improved HX-500 digital camera comes attached to a compact shoulder strap of Surpass shoulder bag. Aside from minor exterior changes, the HX-500 is the first wearable camera to achieve 4K30p that is four times sharper than full HD footage. This collaboration item will be available from master-piece stockists in Japan from Friday, June 13.
