In reality the Lytro has abysmal performance, which questions the value of lightfield technology as a whole.

Instead of capturing the 'light field' you may as well capture most of the image.

Secondly the loss of the 2nd derivative of the k-vector makes lightfield currently unsuitable for use in a microscope (although they are working on it...). Although there might be better techniques for refocusing, such as division in the spatial frequency domain.
