aeolos: hmm.. have you guys actually looked at some red footage?I always thought the reds must be pretty amazing with it 5k and 4k shooting
but from a resolution standpoint the camera is pretty much crap.. the 5k looks only a little better than upscaled footage from a hacked gh2!

seriously look how bad the quality is even at 5k!
The "2000 horizontal lines was the maximum resolution the human eye could perceive" from the BBC may have been true decades ago at the time when cathodic ray TV of 32" were considered as very large. Obviously this perceivable max resolution is also a function of the size of the TV and of other parameters as well (distance from the observer for instance) so I do not think 2K or 4K for the matter are "fixed" limits... 4K is just an ambiguous type of standard today and I am ready to bet that in 10 years it will be just a memory...
