Egami spotted a new Sony patent that could dramatically improve the autofocus performance on future Sony cameras. Imaging Resource writes:

Sony’s patent publication (which means it has been filed and acknowledged, but not yet denied or approved), lays out the groundwork for being able to create unique microlenses with different profiles (shapes), so that the microlenses over the phase-detection pixels could direct light coming only from the desired direction onto the surface of the pixel, without requiring shading. This technology is significant and unique for the fact that the patent implies this would be done on a pixel-by-pixel basis.
This change would give the pixels and overall system much more information to work with in low-light situations.

We are slowly getting there…catching up with Nikon and Canon AF performance!
