@jf_0705 Supposedly, the Sigma 20-200mm F3.5-6.3 DG Contemporary lens was officially announced and scheduled for launch on September 25th, 2025. Since the lens is so new, the profile may not yet be in the publicly available versions of the software. Users would need to rely on either the in-camera corrections (which are automatically applied to JPEGs and often embedded in the metadata of raw files for the software to apply automatically), or manually correcting the strong distortion noted in some reviews until the official profile is released.
Keep an eye out for the next Adobe Camera Raw/Lightroom update, as the profile for the Sigma 20-200mm F3.5-6.3 DG Contemporary should be included very soon.
