Alice Truong has written up a first person account of the Lytro Field camera at DVICE. It’s an interesting article and points out the difficulty of establishing a new category when the current one has not fully matured yet. Digital photography in its current incarnation has yet a little bit more ways to go before it reaches its full potential, presumably when compact mirrorless full-frame cameras become commonplace. The Lytro camera itself faces some technological challenges, not unlike what digital cameras had to go through, re: sensor size, LCD quality/size, etc.
