Yesterday, we found this very complete review of the new Canon EOS-1D MKIV. I contacted Justin and he gave me permission to post a bit of his review, but I really encourage you to go read his post, because it is very complete and he gives you some firm opinions.
“Why the picture of the camera surrounded by all the tools? Because this camera is a professionalâ€™s workhorse.Â Everything about it screams build quality, reliability, customization, and raw power â€“ all the likes of which come together to allow the photographer to take pictures in situations that simply werenâ€™t possibly previously.Â I would say 85% of this camera is pure amazing and praise worthy, but I was shocked particularly at one of the areas I felt oddly lacking.Â Keep reading to find my conclusions on Handling, Performance, Comparisons against the 50D, 5D Mark II, and the 1Ds Mark III, and my conclusion!
This review is the culmination of over 40 hours of testing and comparing aimed at representing typical performance in a real-world environment”
Justin includes coverage of handling, autofocus, image quality, as well as including quite a few still samples. Not to mention a comparison of the Canon EOS-1D MKIV and the Canon EOS 5D Mark II and the Canon EOS-1D MKIII and last but not least the Canon EOS 50D
Oh, and there's a very interesting tidbit at the end of the article describing why super fast frame rates may not currently be possible on the Canon EOS 5D Mark II (ok, he really talks about why the Canon EOS-1D MKIV isn't full frame, but I think you can extend the explanation to the 5D2).
