More often, manufacturers have been making cameras with larger model numbers that cost less than their larger-numbered brethren. For example, Nikon's Coolpix S9 can cost anywhere from $20 to $80 less than the Coolpix S5, depending on the store you choose. Both have 6-megapixel sensors, 2.5-inch LCD screens, and 3X optical zoom lenses. Yet there are some rather subtle differences between the two cameras.
