Some time ago, I complained that there is no profile embedded in the metadata of images taken with the Viltrox AF 28/4.5 (FE) lens. Recently, however, I noticed an enabled embedded profile for such images in ART.
I thought this was related to an ART update, but old ARW images still open without an embedded profile.
The reason is the new v1.11 lens firmware. With this firmware, the Sony a7c camera embeds the working lens profile.
Here are some examples.
