Re: New Sigma 8mm f/3.5 EX DG Circular Fisheye gets excellent review
- My first impression (from this photo)is that the lens has a very
similar amount of purple green colour fringing. Most evident on the
tree to the left hand side, and on the black and white stripes of the
zebra's hind quarters, and other areas of light/dark transition. IMHO
this is the Sigma's drawback, but I'll still use mine (the older version).
- An interesting example of where patching the zenith well would be
difficult because the Sun's image is so near that point. Flare from
the sun extends into the zenith area, so filling the "hole" with flat
sky color probably would not quite work.
