How many people are going to be buying a £2k camera to shoot holiday footage on?
You are missing the whole advantage of shooting in 4k, which is not usually native 4k viewing, but the ability to edit the video with no perceptible loss of quality on conventional sized displays, you can even crop 4k video without even any loss of resolution when transcoding to a 1080p file. Higher resolution video is always better for editing regardless of the display resolution!
No dual card slot is shocking I have to admit, all Nikon full frames have dual cards and even their cheap D7200 crop has dual slots for gods sake.
I agree Caporegime the high video res for editing is a big advantage and of course most people will not spend 2k on a DSLR were there are so many alternatives. I think Canon has aimed this 6D2 at 6D1 users and APS-C users who want to upgrade. That is were problem lays in that it is a lot of money for not much of an up grade / spec.
I have watched and read too many reviews / articles on canon users switching over to Sony. I love my canon 7D and my 400D, EOS 50 before that, however Sony are offering so much for the money.
a1ex2001 that were canon is lacking as the market has more on and shifted so nikon and canon need to catch up and be innovative again. With Sony offering the A7 range starting from £1,000 up to £2,500 for full frame you can understand the appeal. For me there are still quirky menu issues with A7's and Canon's menu system is fairly straight forward. I think Canon can and should be able to produce a much higher spec body. I do hope that canon and nikon do not have mass load of dslr camera body stocks that they need to shift before they can think about designing newer and better one's.
I think also people expect more bang for their buck and that is why being a 7d1 user I did not upgrade to the 7D2. As the spec just was not enough of an upgrade to get me to spend £1,400 on a new dslr body !
That could be the same problem with current 6D1 owners !
