What if there were no 4K available in cameras today? Would you still recommend an A7something, GH4, NX-1, based on their other features? I like some of the high FPS slow motion coming out on new cameras, but not enough to be the sole buying point. I need to record video for work - A few talking heads, how-to steps, finished product, QA testing, etc. It will never be at a theatre near you. I do not need 4K, just clear quality and pleasant colors. Used models are also fine. Staying at 1080, what camera system would you recommend based on quality, features, workflow, codecs, etc. ?
