Version 7.4 rc1 is definitely different in its fine detail rendition (color in particular), but it does NOT reduce the fractal-like image rendition in my Yosemite Pines example. It might address the “color bleed” issue (as yet I have not tested that), but that’s the lesser of two digital artifacting issues with the Fuji X sensor.
See also Fujifilm X-Pro1 Artifacts: Presented in Color and Black and White and my original Yosemite Pines example as well as the larger versions in Guide to Mirrorless, found in my review of the Fuji X-Pro1 in Fractal-like Artifacts: Yosemite Pines (ACR).
As good as the dynamic range and color rendition of the Fuji X-Trans sensor is, I prefer the artifact-free razor sharpness of the Sigma DP Merrill cameras.
* Regrettably, the ACR 7.4 update does not include support for the Sigma DP Merrill.
