The second of our three part series about the Canon EOS 1D Mark IV is a comparison of the EOS 1D Mark IV versus its predecessor, the old EOS 1D Mark III. The Canon EOS 1D Mark IV brings several minor improvements as well as two big new features: the new 16 megapixel CMOS sensor and improved AF system. I’ve compiled all the changes into the handy table below:

As I mentioned, there are huge improvements in the AF department as well as certain aspects of imaging (burst, resolution, ISO). Head on to theCanon EOS 1D Mark IV preview for more about the camera.
Hi I think Canon lV is very good !
You’re right, it’s a fantastic camera to use and I look forward to posting my review on it in the future once there is a production level unit.
It looks great on paper, can’t wait to try it out.
