I've only had one Tokina lens, the 11-16 f/2.8 for crop, but it was excellent and produced many of my favorite images. At the moment I have two Tamron lenses, the 70-200 f/2.8 VC G2 and the 45 f/1.8 VC. Love them both, and consider them 'L quality' in all respects. When I finally add a FF macro I'm pretty sure it will be Tamron's.Tonkina, Tamron...I’m not sure they have the same thing going. Again no facts just my gut feeling.
