Which is which? (5d3 vs D800) - RESULTS

Here are the results from the test I ran on the forums, feel free to interpret them as you want. It appears to some degree people can tell the difference.

Please note these were taken with the same Sigma 70mm F/2.8 lens @ f/8.0, which is one of the sharpest lenses in the world and it's sharpest setting.

The results were double checked.

Thanks to everyone that participated.

Total Accuracy: 58.8% (meaning 8.8% above random chance)

1. D800 - Brush Hairs

Accuracy: 71%

2. 5D3 - Figure

Accuracy: 16%

3. D800 - Bottle Tip

Accuracy: 50%

4. 5D3 - Metal + Crayon Box

Accuracy: 18%

5. 5D3 - Text

6. D800 - Yarn + Labels

Guess which one is from the D800 and which is from the 5D3. I will post the answers in a few days in a new thread as well as the accuracy of the forum members.

Indicate your guesses for the LEFT column only.

Background: I did a comparison for my own purposes of the 5D3 and D800 RAW files. I took both sets of low iso raws, then color and contrast corrected both so they looked very similar in ACR. Finally I rendered the 5D3 file at 36 MP from raw so it matched the D800 size. I was surprised to see how close they were, so I thought I'd share.

Here is the set of 10 crops from the same area of each image:
