Fuji XPro/Xtrans a mistake?

Re: Read the article?

I read the article, and it doesn't say that at all. It's a commentary about the difficulty of demosaicing for this unique filter, and the authors commentary was based on PhotoRaw, which runs at "one tenth the memory of a desktop", SilkyPix, a beta of ACR, and a Jpeg. He suggests all difference, in each instance, are very slight. He admits this is a very new pattern with new challenges to create a comprehensive algorithm. He focuses on the chroma smearing as the big differentiator. None of this surprises me at all, and I'm not sure why it would anyone. It's a new design. These things take time. And certainly, not enough time has passed to say that Fuji failed at what they claimed.

On the other hand, he suggests the Fuji underperforms other DX sensor cameras, and that's kind of goofy considering the quantity of samples out there now and the quantity of reviews out now that say the opposite.

As talented as he may be, I'm satisfied that Fuji engineers are pretty talented as well, and the results so far contrast with what this guy is saying. And that's not even taking into account that this is yet to be a mature tech. A year from now, it might be more relevant to compare the sensors. But we're mostly still working in betas, if there's anything out at all.

But I see he's managed to stir up some traffic to his site, so well done.

I don't know if you read the article but its quite informative. This isn't simply about whether the support is there or not. Its more a matter of the nature of the demosaicing algorithms and their lack of uniform superiority over current lenses with bayer color filters. Its really a matter of math and signal processing.

I'm eager for it, as well. But it's only been a few months since released. They've already stated they are "working on it" and in fact have released a Beta. Frankly, I've been happy with the supplied software, then export to LR in 16-bit .tif files. A year from now when we have full LR support, the questions below will seem moot. But, until then, it's valid to at least raise the questions. But, for me, the IQ is so great, I'm willing to live with the (temporary) inconvenience of no LR Raw support.

If Adobe and others have yet to figure it out, then.... Who else is out there?

I'm simply wondering if (a) the Xtrans will go the way of the previous Fuji innovations and (b) why doesn't Fuji give the algorithm to developers.

Cheers!

The sensor produces amazing image quality. Just because Adobe and others are taking longer to figure out the RAW formula doesn't mean it's a mistake. Patience.

One has to wonder what Fuji is doing by not providing guidance — if not the exact algorithms/techniques — on how to process the raw files.

I hope they provide Apple with the algorithm as I don't imagine the Aperture team trying to figure this out.

So my conclusion, sorry to say, is that the Fuji X-Pro1 X-Trans sensor doesn't deliver what Fuji promises. In fact, it underperforms similar DX sensored cameras.

This is not to say that the Fuji X-Pro1 is a bad camera - far from it - the camera has great lenses, a really attractive viewfinder and design, and in many ways the sensor is great, with low noise and clean data, in the class of the recent Sony and Nikon sensors. It just would have been a better camera with a conventional two-by-two sensor layout.
