Excerpt: Webought this lens to shoot Google Business Views panos as our secondary gear. At first use, we found that it has very little flares, which helps with our current use of it. It´s not as versatile as other fisheyes we own, but it is very robust and simple to use.
Summary: I have been using the lens for about 6 months now and of course I have been extra careful handling the lens especially when removing the front lens cap. Right away I noticed how the lens front adaptor ring fitted just a bit loose and tended to slide off "just didn't fit tight" and has a fine metal...
Summary: I use this exclusively to shoot 360° Virtual Tours & Google Business View tours. I like the lens: Images are sharp and the color is good but it is way over priced! I have a Rokinon 8mm lens with just about the same coverage.
Sigma 8mm f/3.5 EX DG Circular Fisheye review by langier
15 December 2014
Summary: 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. The Nikon 8mm 2.8 fisheye was the best during film days, but finding one years after discontinuance makes them pricy.
