It feels like only last year we were faced with a technological breakthrough. Dual cameras in our phones. Two cameras working together as one to improve image quality, and increase ISO performance. To let us realistically fake the shallow depth of field previously only possible with large sensors. Oh, wait a minute. That was last year.
Dual camera smartphones have pretty much become a requirement now for anybody taking their mobile photography seriously. Already, though, Samsung want to make the whole concept obsolete. They’ve now announced some new mobile image sensors based on dual pixel technology. Similar to that found in cameras such as the Canon 5D Mark IV. Only way smaller.
