NOTE: This article has been edited to add Raw Photo Processor (RPP) and Lightroom 4.4RC to the comparison.

Yesterday, Richard Butler of DPREVIEW fame published an article comparing several X-Trans compatible RAW converters. You can download the RAW file of this demo shot yourself by following the link above. Just scroll down to the end of the DPREVIEW article.

This is an X-Pro1 in-camera JPEG of the original demo shot that was used in the article.

You can click on the image for larger views including full-size. Strangely enough, Richard used a DR200% shot (= a RAW that is underexposed by 1 EV) and film simulation mode Astia. Since Astia offers a different color gradation and more shadow contrast than the camera’s standard (default) Provia setting, this version of the demo image is actually not very suitable for comparing external RAW converters with their respective default settings, which will typically try to mimic the camera’s default settings and look. So let’s do a better job, shall we?

This is the same file as before, now developed in-camera with the X-Pro1’s Provia film simulation mode, using the camera’s default JPEG settings:

Again, click on the image to get to larger views on Flickr. As the demo shot was taken in DR200%, the camera’s internal RAW converter automatically adjusted shadow tones and darker midtones to compensate for the RAW’s -1 EV underexposure, while leaving the highlight tones intact (click here for a more elaborate discussion of how to extend dynamic range). As you can see, Provia offers less shadow contrast than Astia, so the shot looks a bit flatter and also “less sharp”, because increased contrast will give a (false) impression of increased sharpness. So let’s forget about the Astia JPEG shown in the DPREVIEW article. Let’s instead make this Provia JPEG our reference image and compare it with the results of three external RAW converters: Lightroom 4.3, Capture One 7.0.2 (release version) and Silkypix 5.

Here’s a screenshot showing a 100% crop of this Provia JPEG. Click on it to go to Flickr for a full-size viewing option:

Now that our benchmark image is established, let’s have a look at its Lightroom 4.3 version. Lightroom/ACR recognizes the camera’s DR settings (stored as metadata in the RAW file) and automatically compensates (at least partially) for it in its default import settings.

I may have found some interesting news about the 14mm prime. Comparing the uncorrected version of a shot with its software corrected SOOC JPEG version reveals that Fuji’s new XF14mmF2.8 R prime lens is apparently almost perfectly optically corrected. This means that the lens doesn’t really need any substantial software corrections which typically have a negative impact on image quality, particularly near the edges of an image.

Have a look at this example (click on the images for high-res versions):

The image above was developed in RPP 64, a Russian RAW converter based on DCRAW that does not interpret or apply any optical correction metadata that the camera is storing in a RAW files.

The image below is a JPEG straight out of the camera that includes all software corrections in the metadata, since the internal RAW converter of the cameras does of course interpret and apply optical correction metadata stored in the RAW files.

It appears that there are only minimal differences between both versions. This suggests that the 14mm is already fully corrected in the lens and does not need any significant additional software corrections. This is good news, as it suggests that the lens (the examples are from a not yet fully suppoerted pre-production sample) will perform well not only in the center, but also near the edges of an image.

EDIT: To wrap things up, here’s also a Silkypix 5 version of this sample:

Since Silkypix is actually using lens correction metadata in the RAW file, this result pretty much overlaps with the SOOC JPEG.
