Sorry, had to get this off my chest: I know that we don't NEED Full-Frame sensors to take good pictures. The problem is that the 36x24mm negative that we know from 35mm film has become the standard. Free markets NEED standards - it enables a level playing field and enables competition. Right now, the manufacturers describe everything (even Point-and-Shoot cameras) with focal length equivalents. ("28-210mm equiv." for instance.) That's because 35mm is the standard. So one of two things will have to happen: we either need to set a new standard, or the market will have to develop FF sensors. I expect digital SLRs and RFs to feature Full-Frame sensors within the next few years. Thoughts? Comments?
