    For those trying to replicate the eye's picture (one eye only), you'll need -
    22mm lens, f/2.1 max aperture and f/8.3 minimum aperture (35mm equivalent - 16.5mm lens, f/1.6 max aperture and f/6.2 minimum aperture)
    50mmx50mm film/sensor with 6.5 stop dynamic range (20 stop dynamic range for video) and ISO range of 25-60000.
    15 megapixels (100 megapixels and 1/10 shutter speed for video)
    Software like the Oloneo Photoengine that could manipulate different colors from different lighting sources.
    Monitor to display the same dynamic range and color and gamut as the eye.

    The eyes resolution isnt constant, neither is its light sensitivity. The center of the eye has the highest resolution (most cones), but the lowest light sensitivity (fewest rods)--in fact the center is so bad at night vision there is a slight blind spot in the center of your vision at night. Its all about rods, cones, and how they're distributed.

    As for color, the brain highly manipulates the results. Also rods and cones react to color differently, cones are nearly blind to low wavelengths (red), which is why red roses appear black at night, and why movies often use a heavy blue filter when shooting night scenes.

    Most rods are inactive in the day and are not used in core vision.

    Yeah, but the Eye's lens is utter ****. Not even as sharp as a Sigma lens.

    But do note that the eye has a light sensitive area larger than full frame cameras, therefore it can actually be less sharp yet be able to have the same sharpness as full frame cameras. If the eyes have regular pixel placement, any lens sharper than the Nikon 28-300mm is gives no extra benefit.

    It gets better. The eye has a honeycomb layout of pixels, and thus do not suffer moire effect. Also it is HORRENDOUS as an image capturing device having a very small sweet spot in the middle of the image. The brain combines a constant video feed with short term memory to make our eye appear to be far better than it actually is. In some cases it even makes up things that aren't there (such as filling in the blindspots in our vision).

    And merging data between each frames in each frame to create even smaller detail, 6 times more detail.
