Having used a 6D a bit I say the 6D technically wins in everything except build quallity and the feeling in your hand/against your eye. It even wins at focusing in low light (when you only use the central point of course). But some some images from the older cameras just look more... film like compared to the new boys (especially colours of nature). Still love it, but I'd trade it in for a 6D any day (ISO 25k is cleaner than our 1250
).
Finally managed to get my Yongnou YN-568EX into working order. It works flawlessly with the 1Ds and with the Pixel King PRO triggers.
And a pic from tonight (ISO 1250)
Big up
