comment:I had been looking on and off for the full-frame 8mm Sigma Circular Fisheye, but found this on E-bay at a reasonable price & went for it.
Most definately a strange effect lens. You get a circular view - somewhat smaller than I expected on the Alpha sensor, as I suspect it was designed with the slightly smaller cannon 1.6 crop in mind.
One thing to be aware of is that the lenscap is in two parts - there is the cap which fits over the lens but there is also a ring which holds the cap that detatches. This is not easy to spot and the first shots I took I had left this on which made it visible.
This lens provides an almost unique view of the world, somewhat like looking down the barrel of a drainpipe.
Not something for everyday use, but great for a bit of fun and experimenting with.
