Latest Review Posted | Sigma EX Circular Fisheye 8mm F4 I was surprised, it was better than I was expecting. Using the center point autofocus works consistently well on K-1 MII . Although there are sharper and more contrasty lenses out there, I find I end up using this often on K-1 for the circular fisheye effect. For daytime shooting, F7.1 seems to be the sweet spot, and it handles sun in the frame pretty well. If you're on a budget, this autofocus circular fisheye is very good. |
