I get it, the lens looks awesome. I could always get both and just return which one I don't like but I don't have a theater to run for tests. If it was a nikon mount I might have picked up the Tokina off of you.
Does anyone know how the Tokina 28-70 holds up when blown up on the big screen? I'm currently choosing between this, the Nikon 28-70 (Bourne len), or just going primes.
