I don't find a profile in the Adobe Lens Profile Downloader for my Canon 50D and Tamron 18-270 DiII VC B003E combination. This lens is included in the list of supported lenses on the lens profile support page. There's one profile for this lens but with a different Canon body, and for jpeg only. I need one for raw. Do I need to go to the Lens Profile Creator and create a custom profile?
