I never thought you used fisheye lens. 
At one time (Last X-Mas) I am thinking to buy this lens. What do you think. 
TOKINA AT-X 10-17MM NIKON FISHEYE ZOOM  
The reason I changed my mind because they bring out a new lens. 
TOKINA AT-X 11-16MM F2.8 NIKON II (not fisheye) 
Give me some suggestions please. |
