Yes I do. Lack of internal 4k is why I passed on the A7S. GH4 is 4k, so it's not living in the past. Samsung NX1 is 6k down-scaled to 4k and H.265, so it is good for the forseeable future. A7S is priced like 4k, but is only HD. It is the only one of the trio missing this highly sort after feature. As for comments like blah blah blah is "impossible"... well five years ago all of this was impossible wasn't it? Mark my words, Sony has the technology to do 4k in the A7Sii. They probably could have done it in the first model. The bottom line is this, the current A7S is a $4500 camera for anyone that would like to shoot 4k. So this means the A7S really is not priced where Sony planned it to be. Meaning fewer sales. For this reason I'm certain that getting 4k into the successor is a top priority.
