SonyAlphaRumors: Sony presents 2x2 On-Chip Lens (OCL) technology for high-speed focus, high-resolution, high-sensitivity, and HDR:
"In conventional technologies, the variance in sensitivity per pixel caused by the structure (described below), which places an on-chip lens that spans four pixels, was a major issue. However, we have successfully developed a high-performance image sensor with high image quality through optimization of the device structure and the development of a new signal processing technology."
The main features of the Sony lens structure:
- Phase differences can be detected across all pixels
- Improved phase difference detection performance (focus performance)
- Focus performance at low light intensity
- Focus performance that does not depend on the object shape or pattern
- Real-time HDR output
