This is a Tamron SP 24-70mm f/2.8 DI VC USD Lens for Canon. 

As you can see, it was really well-kept... as a matter of fact I kept it in storage from 2014-now because I stopped using Canon for photography. 

Please note the scratch on the distance/focus meter (it is purely cosmetic).

You can return it after seven days if you're dissatisfied in any way, but I was always pleased with the results.
