Sigma 4.5 mm f/2.8 EX DC CIRCULAR FISHEYE HSM
8. Vignetting
Vignetting was one of these few categories where the untypical nature of the lens didn’t cause us any problems. You don’t have to take any test photos to write that the light fall-off in the frame corners amounts to 100%. What’s interesting, it’s not a drawback, just a property of a circular “fisheye”.
