It's interesting to see how much technology has progressed through 2001 to 2010. Film still produced grainy images with ISO 800 rated film back then, and we now have pristinely clean photos at ISO 12,800. Without a doubt, the technology has been steadily improving, until it has come to a point where technology may just lend several helping hands to those who lack a genuine understanding of photography to achieve better photos.
Like many established camera manufacturers, Canon certainly has a hand in revolutionizing technical progression in the camera scene. In fact, they were the first to have launched the professional 1D series way back in 2001. Since then they have been constantly updating this particular series over the years. Recently, the Canon EOS 1D Mark IV made its global debut, and what an advancement it is over its predecessor, the 1D Mark III.
Before we continue the rest of the article, might be prudent to understand that it's unfair to compare the brand new 1D Mark IV with the almost three-year old 1D Mark III, but being the only APS-H DSLR out there (the Leica M8 doesn't count), the 1D Mark III is essentially the closest competitor it has. There's always the Nikon D3, and the upcoming D3s, but as both these cameras are full-frame by nature, it would be unfair to compare these cameras on even ground. With the D3s having a lower megapixel count over a larger physical sensor, the noise is expected to be better than the 1D Mark IV, but these are just assumptions, and we will have no way of verifying this since we haven't had the opportunity to test the D3s yet.
That said, going by the 1D Mark III's history, we were pleasantly surprised to find that there were no discernible concerns with the new 1D Mark IV and we've had a pretty good time with the DSLR. Read on for our full assessment.
