New Olympus patent describes improved phase detection AF tech.
Egami (translation here) spotted an Olympus patent describing a new on sensor phase detection tech. The idea is simple. With an addition of a second layer every single pixel can be used to enable phase detection AF. if it works we basically would have the best solution ever…even better than the Dual AF Pixel solution from the Canon 70D. But we all know there is usually a huge time gap between patents and real application on final mass products.
