So as an enthusiast....
Full frame this one and I am all over it like white on snow. Even if the body bumped to $2k U.S.
Leave the total pixel count the same, etc, etc. Just give me the better pixels.
I would be more than OK/ w/o 4k vids, 7 - going to 9 FPS, no viewfinder blackout, DP AF,
take the guts out, put a FF sensor, put it in a 5D IV body and DONE!
