Sony has some of the best 4k video cameras out and more to come at Photokina? Sony is really pushing towards the consumer market more and more in my opinion, but we shall see what the future entails as far as cameras. According to SonyAlphaRumors, it will be an E-Mount video camera!

I can confirm via trusted sources that Sony will indeed soon announce a new high end E-mount 4K video camera. I have yet no 100% reliable specs a part of the obvious 4K recording capability.
