Re: you forgot

We should always be careful with interpreting test data between the sensor formats. When comparing similar pixel count, APS-C size sensor packs photo sites at higher density and challenges the lens with higher resolution requirement. OTOH, full frame sensor's edge photo sites are approached at higher angle which can add to chromatic aberrations, fringing and vignetting.

I don't have a constant access to FF camera (D800e would be ideal) in order to repeat these tests on FF; someone else would have to do that
