Sigma 8mm f/3.5 EX DG Circular Fisheye
(From Sigma lens literature) Sigma’s 8mm f/3.5 EX DG Circular Fisheye are a unique approach to creative photography. Images created by fisheyes are a circular, curved distorted view of reality. It allows photographers to shoot creative images by taking advantage of the acute perspectives that are invisible to the human eye. This Sigma fisheye produces a circular image with a 180º angle of view within a black surrounding frame. A minimum focusing distance of 5.3 inches and a magnification ratio of 1 to 4.6 allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. For photographers looking for a creative venue this Sigma fisheye is a good choice.

I've used fisheye lenses for most of my career and for the past 20 years have had to learn to use the circular fisheye lenses for one of my clients.reviewed December 15th, 2014 (purchased for $591)
The Nikon 8mm 2.8 fisheye was the best during film days, but finding one years after discontinuance makes them pricy. Also, the Nikkor 8mm 2.8 is a humungous and heavy optic.
The Sigma 8mm lens is both compact and lightweight. It has little flare with point source lighting which is a plus and stopped down to f/11 or so creates a nice star effect.
For my application, Serbo-Byzantine iconography, this is my go-to lens to shoot entire church interiors and domed ceilings. No other lens will do.
I use mine on a D800 for maximum image size and quality. My f/3.5 replaces my f/4 version for a couple of reasons, mainly that the image circle gets very close to the edge of the frame. The f/4 is about 1mm smaller in diameter and since every pixel counts, this lens covers the frame better.
However, like my f/4 version, this lens has a focus issue in that infinity focus as marked isn't infinity focus. Both my circular Sigma fisheye lenses achieve infinity focus about 1.5 meters instead of the marked infinity.
Knowing this and that the lens has such great depth of field, one only needs to be aware, turn off the autofocus and wing it with zone focusing, just like the good old days, thus nailing the sharpness at its prime.

Real Fun-lens - funky-punky.... optically very strong, sharp, complete circle (not that bullshitcercle from Peleng 8) nearly without flare (forget the cheepo-Pelengo....!). Very good construction, but take care of the frontlens....reviewed March 19th, 2012 (purchased for $620)
