With the announcements of the Canon 6D and Nikon D600, owning a full-frame camera just got a little more affordable. Since many on the Internet have been wondering why they're not more affordable, I think it's worth mentioning that it costs more to make a larger sensor like this, because they get fewer sensors per wafer just due to the size; and small imperfections on larger sensors will mean fewer sensors will pass muster. All that to say it still costs a lot more to make a sensor that big. You can get at least twice as many APS-C sensors from a single silicon wafer. Then you need a bigger mirror and a more robust mechanism to move that mirror, as well as a larger pentaprism and the optics to support that; and naturally all of that larger size requires a little more internal support and external coverage from your inner frame and outer magnesium-alloy shell. So I'm pretty sure it's not a big conspiracy; it just takes more of a few key elements to make a full-frame sensor camera, and I'm sure as soon as either company can figure out how to undercut the other on price to get more of their own cameras into more hands, they will.
