    I was told by the camera dept. assistant that this adaptor works on all Canon lenses and it did not. My Canon EF 28-105mm did not fit and neither did any of my older Canon lenses. I had to paid a $35 restocking fee. One star became I really don’t know if it works properly.

    BBY website states that this unit will work with Canon EF and EF-S lenses. I was also advised the same by store associate. Unfortunately, it does not, and will not work with Canon EF-S lenses. It is going back.
