Adobe posts Lightroom 4.4 and ACR 7.4 release candidades, promises proper Fujifilm X-Trans sensor support at last. Also, bug fixes and some new cameras and lenses supported.

It is not every day Adobe goes back and changes the de-mosaicing algorithms for previously supported cameras, but this time they've done it, and the first preliminary reports are in. DPreview's Amadou Diallo runs some tests with a couple of X-Pro1 raw files: 

"Capture One Pro 7 produces more crisp results than ACR with contrast and saturation defaults that more closely mimic the in-camera JPEG. Having said that, however, ACR 7.4 RC avoids the edge halos and even more obvious aliasing patterns that exist in the Capture One Pro 7 renderings of our real world and studio test scene. Overall, the ACR 7.4 RC files deliver more realistic, natural results in areas of organic low-contrast detail like the foliage in the street scene above and the fuzzy balls in the studio scene below."

Furthermore the general consensus of X-Pro1/X-E1 camera owners is generally very positive. Most people claim they get results roughly on par with what they get from Capture 1 pro 7.02, and that's a good thing. There's still some way to go until both programs deliver excellent results, but the situation is far  better now, than it was just a couple of months ago. 

The updated Lightroom and ACR versions do not only add (improved) support for Fiji's X-Trans family, but also for most of the latest cameras and lenses announced, and a couple of bugfixes too. They even include support for the Haselblad Lunatic Lunar, I had to double check the calendar but no, its not April the 1st yet. Anyway, here's the full Release notes file:
