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. see http://www.cnet.com.au/nokia-vs-lytro-the-refocusing-challenge-339346170.htm http://www.cnet.com.au/nokia-vs-lytro-the-refocusing-challen...
