We've been adding new information to our product database to make it easier to understand the characteristics of camera sensors. The idea of megapixels is generally well understood but, mainly because of the way they've historically been presented, sensor sizes aren't. We feel that relating these two pieces of information gives a clearer understanding of how they interact. To achieve this, we've added the new field: "Pixel Density" to the database, to help when comparing cameras. We think you'll find it useful.
