For the purpose of this discussion, Bayer sensor is used here in the sense of "Bayer sensor without or with a very week AA filter. It is also assumed that the rest is the same, number of Mpixels, the underlying manufacturing technology, same generation of Sny sensors, etc.

X-trans wins:

  • X-trans outresolves Bayer sensor without AA when you shoot patterns with very dense horizontal and vertical lines
  • Bayer generates moire in this area, it is easily fixable in PP, but the resolution does not match X-trans

It is not easily fixable. You can remove most of the colour rainbow in the fabric for example, but the B&W lumi part of the moire cannot be removed.  If you think it is easy, you have not tried...and thus should not make statements

Bayer without AA wins:

  • Bayer outperforms X-trans pretty much everywhere else - images are cleaner at high ISO and it resolves more details both at high and low ISO

Unproven:

  • There are some claims that X-trans handles green patterns better than Bayer, I I simply don't see it in the posted images.

Additionally, I've been shooting with cameras without AA for at least 5-6 years and do not see moire to be affecting than 1% of my photos. Fabric, skins, eye-lashes, bricks, whatever it is, the moire is either invisible or is fixed by color noise removal. It doesn't show up. But I must admit, I never shoot objects with B&W horizontal lines.

Conclusion:

Modern Bayer sensor technology is better for 99% of practical cases.I am happy to admit that X-trans will handle better the remaining 1% cases If your photography requires you to primarily shoot horizontal and vertical line, than this number can be higher for you.

So, answering my original question which started this discussion, Yes, for most practical cases X-trans has lost it's superiority to Bayer without AA.

It is really not clear why and if Fuji will keep X-trans cameras in their product line. I suspect the time of X-TXX and X-ProXX with Bayer sensors are not that far away.

PS.

There is nothing to worry about though, the great X-trans cameras that you have today will continue to take beautiful pictures, they will beat X-A5 in terms of AF, handling, quality of the EVF/OVF and will offer more SD-Card slots, etc.

Not sure what are you talking about. Here is a comparison of the T20 with the A5 . I used Silkypix at default settings for xtrans demosaicing. The only thing I've done is that I turned off smoothing. I prefer xtrans here by a large margin... Default colors are much nicer, better resolution. I didn't even touch saturation or anything else.

I don't agree.

Bayer isn't better here:

Or here:

Or at High ISO either:

No idea what you talk about. Fixed all moire in my photos many times, never had a photo ruined by moire.

Anyway, it starts to remind me the good old Monty Python sketch.

Here is another comparison of the same files. Check out the feather. Xtrans image has better resolution and very clean and natural greens. The A5 has Canon-like yellowish greens which I always disliked. I am happy to pay extra 200 dollars just for those nice xtrans greens... Love them.
