Canon 24-85 USM update for 5D ?

Wrong. I'm using the 24-85 USM profile from the Adobe Lens profile. I'm not adding anything. It does not mean I have a bad copy !

When used wih this profile, the result is fairly good. Now I'd like to have opinion of owner of this lens who have upgraded it to either Canon or Tamron 24-70.

Is the upgrade really worth it ?
