Rumors suggest that Samsung is preparing to turn up the heat in the camera phone race with the upcoming 16-megapixel Galaxy S4 Zoom. As appealing as a Galaxy S4 variant with optical zoom and image stabilization sounds, Nokia may soon steal the show with the most impressive camera phone the world has ever seen. Featuring a 41-megapixel PureView camera and a xenon flash, the Nokia “EOS” has leaked a number of times already. But now, a video has been released by ViziLeaks that reveals the handset’s mechanical shutter and image stabilization feature in a close-up of the camera assembly. There is still no word on when the EOS might be unveiled but in the meantime, the full video follows below.
