These were all shot with a 70-200L f/4 IS at 200mm. Tripod mounted, Av mode, ISO from 100 - 12800. I moved the tripod closer for the 5D3 shots. These are 800x800 pixel crops. In each group, the 70D is first, 7D2 is second, and the 5D3 is third. All processed with DPP 3.14.41. All noise reduction is turned off as is auto lighting, digital lens optimization, and lens aberration correction. Looks to me like the 7D2 is right in between the 70D and the 5D3 (which is where we expected it to be).
Since we're limited to 8 images per post, this will be in 4 postings. Hopefully I can get them all done before someone starts commenting.
