PopPhoto has posted their 3 page review of the Canon EOS-1D MKIV and found it was made for “Sports shooters or anyone who needs a fast burst rate in a body built like a tank” – but they also thought the autofocus was “slower in our tests than the old one, even in bright conditions. This isnâ€™t to say that its performance was terrible, but in a camera of this caliber, we expect more.”
They go on to compare the Canon EOS-1D MKIV to the Nikon D3s – but you'll need to read their comments to find out which one they'd pick and why.
Oh, and if you want more in depth information on the Autofocus issues – go back and read the Canon EOS-1D MKIV review that canonrumors has on their site (this was originally hosted on Justin's site and we covered it, but Justin has since been hired by canonrumors to post for them).
And, our thanks to @fcwestfall on twitter for alerting us to the new review.
