A new patent has seemingly revealed Sony’s plans for a potentially game-changing new lens – that being, one that lets you take a photo, and select the focus at a later point.
News of the Japanese patent comes courtesy of SonyAlphaRumors, who has suggested the product would be a collaboration between Sony and Light.co, who have held a partnership for over a year now.
The lens is made possible by including several smaller lenses inside a larger single lens. Gathering detailed information about the depth of the scene in front of it, the lens would then allow the user to select the focus at a later point. Essentially, it’d capture the image at different focal lengths, allowing you to select which you prefer afterwards. That it comes in the form of a lens rather than an entirely new camera model opens but many opportunities. Check out the diagrams below for an idea of how the design may look.
This newly published Sony patent disclos(es) 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 then be combined to created a Light Field image.
A Light field image gives you complete 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.
Recent advancements in sensor resolution could well mean a lens of this caliber could soon be a reality, but quite when it would hit the market remains to be seen.
