Exactly a year ago Sony announced a joint partnership with the Light company. And finally we are getting an idea of Sony’s plan with that new tech:
I just spotted this newly published Sony patent disclosing the design of a future E-mount Light Field Lens! The patent shows how you mount the lens on the Sony A7 to create multiple images on the sensor. Those images will than be combined to created a Light Field image.
A Light field image gives you completely depth of field control. And you can select what has to be in focus AFTER you have taken the image. The drawback is that you need a lot of fine tuned computational power to get rid of possible artifacts.
For now we know this is just a patent. We will see if Sony management will give this idea a green light in the near future…
