I haven't used the Canon. 28-50 is not a very long range. I think I have a 28-50 Soligor in Canon mount. I don't use it much. The Tokina is an excellent lens. I have it for Konica, Canon and Nikon. The one in Canon mount has had the most use. On the long end it's pretty slow so using it with an F-1 with an L D screen brightens things up.
