The thing with technology is that no matter how advanced and updates you are, you really are not. Before seeing the new Lytro, I was quite certain that the DSLR was advanced but now, I am in shock of what is possible.
For about $400-$500 you can purchase your very own Lytro Camera available in 3 colors. Equipped with the all-new type of shooter called a Light Field Camera that captures the colors, intensity and vector direction of the rays of light and then uses powerful software to focus and re-focus, anywhere in the picture, even after it was taken. This means for you that you will no longer have any shutter delay. This is truly a spectacular device.
