I’ll be swapping my 5D Mark II DSLRs for two EOS-1D Mark IVs. For me the 1D Mark IV is a big leap in terms of imaging technology. It was the high ISO capabilities that originally attracted me to the 5D Mark II, but with the 1D Mark IV I can now get better build quality, superior high ISO ability and a vastly superior AF system, so it’s been an easy decision to switch. I would say, hand on heart, this is the best digital SLR I have ever used.
Jeff also includes a couple of high-ISO sample images (RAW files processed with Apple’s Aperture 3), shot at ISO6400 and ISO12800 with two lenses, a Canon 24-70mm f2.8L USM and EF 85mm f/1.2L USM, and I must agree with Jeff, the skin tones look terrific!
In conclusion, I don’t think Canon has completely caught up to the D3/D3s autofocus, but I do think that it’s close enough that technique and lens choice can make the margin negligible. I also think there’s no reason to assume you can’t trust the Canon 1D MK IV autofocus – based on my own extensive use of the camera in the last three weeks I’m convinced it focuses just fine.

I’ve put up some photos (click the image for a larger version) and two video clips taken at the 1D4 launch. The photos were snapped with a Nikon D5000, and either the Nikkor 55-200mm VR or AF-S 35mm f/1.8G lens attached to the camera. The video clips were taken with a Canon Powershot SX200 IS. Photos were processed in Adobe Lightroom 2.4.
