Rex, the OP - remember him? - made no mention of an interest in video. So why are we trying to push 4k video on him? FWIW, I do have a 4k TV, and there is nothing presently broadcast in UHD. I'm sure that'll change, but I'm also pretty sure it's going to be a slow process. In fact a great deal of content shown consists of old repeats from before HD was even thought of, which has been digitally upscaled and enhanced! The 4K TV is great for viewing still slideshows on though. And if you make prints less than exhibition size, 12 Megapixels is still sufficient. To paraphrase some famous photographer or other: If the picture is good enough, nobody cares what camera it was taken with. Besides, more and more people are viewing content on tiny portable screens, where 4K and > 12 Mp is just total overkill. 4K on Youtube? LOL!
