Question about TDP's sample crops

[LetTheRightLensIn]

Something else to consider - the 60D/7D sensors have stronger AA filters than the newer 18MP sensors (beginning with the T4i), so the 60D output looks softer at the pixel level compared to the T4i/T5i/SL1/EOS M. The output from the newer APS-C bodies does not look all that different from the FF cameras as far as pixel level detail in ISO 100 test shots is concerned, have a look:

5DIII vs. EOS M:

EOS M vs 60D:

I wonder if it is the lack of split greens on the CFA? I know that the 7D originally suffered from major and weird "mazing" artifacts until they came out with new debayer algorithms for it but they also every so slightly made the output softer (comparing pre-fix to post fix RAW converters output from it).
