Upgrade form 7D to 1DIV

[HDNitehawk]

It is massive.

The difference in the AF system outweighs any perceived benefit that you may think the 7D has.
The quality of the pictures directly out of the 1D IV are superior to the 7D’s directly out of the camera. The 1D IV has much better contrast than the 7D. You can get close to the same image quality with the 7D if you are willing to work at it in post.
I thought it was a worthy upgrade when the 7D was $1,600 and the 1D IV was $4,500.

The success of the 1DX has resulted in more used 1DIV's becoming available on eBay and CL in the $3000~3500 range.

Now that you have definitively answered the question of the 1D IV vs. the 7D, I would like to pose a little different question that I have been woundering about. Now that a used 1D IV is in the same price range as a new 5D III, shouldn't the 5D III be in the mix with this comparison? When comparing those two it gets a little muddier (keep in mind one is used and the other new). Which would provide better IQ, DR, and/or better focus? I get that there is a 1.3 crop factor difference, and a frame rate difference, and focus with TC's; but then I am tending to be leaning towards wanting a FF and I really like the idea of a camera that handles low light noise. So I think I would be leaning more towards the 5D III (although I am quite sure I would like the 1D IV if I had one), and I like the idea of a new camera with warranty if I am going to spend that kind of money.

Rick - Any thoughts in comparing a used 1D IV vs. a new 5D III for about the same money?
