A common problem with slim point-and-shoots is that users with larger hands may find it difficult to hold and operate the camera. A recent Sony patent (PDF) for a foldable grip may just resolve this issue, and I have to say it is quite clever.
According to the diagrams, it's possible to increase the grip's surface area by pulling the front plate out sideways so it folds and becomes a grip. Presumably, this will also expose the lens and turn on the snapper, much like the Cyber-shot T-series shooters.
But as with all patents, this apparatus will remain a concept until the company decides to implement it. So don't hold your breath.
