Personally I think Canon did a great job on the 5D Mark III to really dominate their own personal DSLR Video market, but the new 1DX will still be their flagship camera for high speed sports photographers. The 1DX sports a 61-Point High Density Auto Focus, dual compact flash media recording, Gigabit Ethernet Port, and up to 14fps burst mode. And obviously if you still plan on doing HD Video, it has all the features of the 5D Mark III and more, but beware of that $6,800 dollar price tag. If you were waiting on one these cameras, more of the EOS-1DX has arrived in stock today over at EOS-1DX full product page B&H.
