When I bought my first 5D MKI I had the impression I did a downgrade from my 40D, technical old, limited menus and buttons, but IQ (ISO up till ISO 3200), bokeh,... was a big step forward!
That's from a semi pro to an older pro camera.
Now I have the same feeling with my new 6D (comming from a 5D MKII).
Cheaper feeling body (like I have a 650D with lots of functions), but the IQ is also a big step forward, ISO 12800 is surprisingly good, no disturbing noise!
That's a body downgrade from a pro to a starters fullframe with IQ upgrade.
The "feeling" of a body/functions can be misleading, it can feel old or cheaper, but the IQ inside makes the difference!
