Consumer 4K is arriving. Well not really 4K, the redefined by RED 4K, which resolves around 2.8-3K with a decent lens after de-bayering. All in a 1/2 CMOS sensor, so each pixel will be that much smaller with all the attendant noise and lack of dynamic range that follows. With cheap glass, higher noise and compression, it will be interesting what this camera resolves, or what your average consumer would even play 4K back on?
