Often related to as a full frame start up camera? - its a superb camera with amazing high iso images. Auto iso is a game changer for me, coming from a 16 year old 5D classic of which I loved, trying out an old 6D MKI the difference was night and day. The 6D's still enable great skin tones of which is most important to me. I kept the 2nd hand 6D and traded in 2 x 5D's and a 550D for a new 6D MKII - no regrets whatsoever.
