1d MK4 vs 7D comparison...RAW files....

These were taken at CES.

First of all I am amazed that I could take pictures at all because everyone were showing and pushing. I wanted to hit someone but I was afraid of going to jail.
Canon people have no manners. I forgot to use 5d2 because I was so mad.

Download below.
800-6400 ISO.

There is a discrepancy in metering for some reason. Same lens was used but because there is different crop factor metering was based on smaller area.

All I know is that ticker was in the middle on 0. I don't think that slight metering discrepancy would affect the results.

I did this: moved all sliders in ACR to 0.
Opened comparable files and cropped the center.

7D files have about equal amount of Luminance and Color noise on the other hand 1D MK4 files have more Color noise and hardly any Luminance noise.
I still say that because 7D has higher pixel density it has more details.

Even if 1D MK4 has slightly less noise (very debatable) frankly, I don't see $3.5K difference.

Have fun.

The only time a smaller sensor with the same pixel count is superior to a larger sensor (aka higher pixel density) is when you are focal-length limited.
