This is an old debate. Personally, I prefer test results to theoretical suppositions--particularly since the theoretical suppositions go in both directions.

I do agree 100% with you. And theoretical suppositions made by forum collegues may be many times based on aspects we cannot know for sure, eventually we may guess. Additional, image quality is not only resolution.

For example, here's a test done by Liquidstone, a well respected bird photographer. Tests like this, together with my own experience with my 7D and 5D3, have convinced me that the reach advantage offered by higher density sensors is real.


While in your link I would agree there is a marginal advantage for 7D vs. 5D2, ISO200 and a low contrast cvasi-monochrome target do not tell the whole story. I have done my homework somewhat different. Below is my result. Some notes:

  • Images come from 7D and 5D3.
  • Distance to subject is always the same. Lens is always EF 300 f/4L IS USM. 7D images are matched to have similar size as 100% crops from 5D3.
  • Postprocessing is done something like "best resonable effort" - actually some 1-2 minutes per image in LR. Digital exposure is always 0 (no push / no pull).
  • LR sharpening is same in all pictures, NR varies for obvious reasons (7D needs always more NR vs. 5D3).
  • For the moment I tell you only left images are always from the same camera, right images from the other camera. I let you and the collegues guess which is which. It should be clear.

ISO 100
