When I import my photos in lightroom, the ones taken with Sigma lenses does not show the exact model designation contrary to Canon lenses that are presented with the full information. On my sigmas only the focal length range is shown. It's not that lightroom doesn't know what lens it is though. If I apply lens correction the correct lens is detected.
Is there any way to get lightroom to write complete exif lens information, not just lens focal length range?
