Sean Reid, of Reid Reviews, just published a follow-up article to his test of the Fujifilm XF27/2.8 lens, titled "XF Lens Res. Revisited". In this article Sean repeats a number of his previous tests of Fuji and Zeiss lenses, but this time using AccuRaw. In addition, he also tests the effect of software correction of lens aberration on lens resolution. Unsurprisingly, software correction of lens aberration can result in noticeable reductions in resolution. Many modern cameras are sold with lenses that have very significant levels of aberration that is automatically corrected by the raw developer. But "there's no free lunch".
Resolution loss due to software correction is a topic that isn't often discussed, and so Sean's article is well worth the read. You can find it here. Note that access to Sean's site is by subscription only; Sean doesn't take any advertising, allowing him to produce reviews without fear or favor.

Sean Reid, of Reid Reviews, just published his extensive test of the Fujifilm XF27/2.8 lens. As usual with Sean's reviews, it very comprehensively covers the lens' performance as regards resolution, aberration, vignetting, etc.
For this review however, Sean also took things a little further, and tested the effect of the raw converter used on apparent resolution. He tested Lightroom, AccuRaw, Raw Converter EX, Capture One and Iridient Developer. You might think that all of the converters were about the same. Not so. In fact Sean concluded that "The results above seem almost as if they could have come from five different lenses".
And which converter came out on top? Sean goes on to say that "And, while its conversions may show some artifacts, it seems clear to me that the AccuRaw conversion does the best job of showing us the resolution levels this lens is capable of".
