    It appears there are some with higher resolution, for still images.
    If you consider also that the eye is a video camera, and not just a still image there are none that have the same capabilities.
    There may be some with high resolution, and some with high frame rates, but none have both the high resolution of the human eye as well as instantaneously refreshing frame rate, or the ability to change focus from infinity to one foot in less than a tenth of a second, to maintain constant focus on elaborate moving images and patterns, or to have such a wide field of view and maintain clarity.
    In the example of a telescopic lens on a satellite, for example, the field of view is so narrow that it would take days for it to pan across the earths surface, whereas the human could see the entire planet from that distance, plus millions of stars in the periphery.

    Also the satellite could not instantaneously change the focus to have a look at something a few feet away. It would probably take 30 seconds or more, and be unable to see anything less then ten feet away.

    There are specialized lenses, specialized sensors and flashes, telescopes and storage media, but none of them are comparable in all round effectivesness.

    With each progreesion into a specialized field there are sacrifices made in other areas.

    For example, with the 4,000,000,000 pixel camera sensor, how long of a delay is there between the time you push the button to take the picture and the picture is actually captured or ready to display on a playback device?

    I'm guesssing at least 6 to ten seconds.

    Baseball would be an entirely different sport if it took 6 seconds for the human eye to process an image.

    Every single at bat would be a strike out, as batters swing seven seconds after the back catcher has the ball.
