Hey Peter,
Just wanted to say I own the Tokina 100mm as well, and is by far the most amazing lens I own. On my old Nikon D80, or on my new D800 FX camera, everything is just razor sharp and very pleasant Bokeh. I never leave the house with it and use it most next to my 50mm prime
Kind of wish I waited, $300 is such a great price compared to what I paid!
