Well, for optics, you pay for what you get.
The optics from the Tokina 10-17mm Fisheye is superb, For APSC , this will be the best FE I felt.
However, having moved on to a FF, I ditched the Tokina :cry: for the Zenitar. Optics cannot be compared to the Tokina but for its price, I have no complains.
Forget about those cheap add on FE , one will be better off using a P & S with FE effects.
