Re: X-Trans advantages - fact or fiction ?

It is very difficult to do a controlled test. Did you use the same lens/aperture/exposure on both cameras of the same subject at the same distance/lighting?

Using the same lens would require adapters, and that would also call all but center of the image in question, provided they were both carefully focused.

Then the next issue is that there is no truly neutral rendering with no sharpening, no noise reduction, etc. the specifics of the demosaicing algorithms influence this whether it's Bayer or Xtrans.

Color profiles and tone curves may also play a role in perceived sharpness, I guess.

The bottom line is that even with controlled parameters, you are still stuck with tweaking the output from each image to see what is the best that you can get from each, which is subjective. It's no wonder that reviewers throw in comparisons of default jpegs.

Have you wondered why DXO doesn't test Xtrans sensors or lenses with XTrans? This might explain it:
