Sigma 15mm F2.8 EX Diagonal Fisheye Lens for Nikon-AF Camera

Rating:
Summary: Great lens
Review: I found that Sigma 15 mm & 20 mm lenses great. Put on my Nikon D100, I can always take picture on every light condition. Especially in shady places where I set the ASA 800 - 1000, this would create a wide depth of field.
I don't see any setback in Sigma 15 & 20 mmm lens.
