Recently a company called RealPix announced a point and shoot style camera designed for Realtors. I has 22mm fixed focus lens, 640x480 pixel resolution, "high-powered" built-in flash all for $299. It is expected to ship in July.
In my opinion, this camera will not impress Realtors. I have a lot of Realtor friends and very few would buy something like this. All the Realtors I know already have more sophisticated camera's in their cell phones (minus the 22mm lens).
