| This circular fisheye lens produces circular images with an angle of view of 180° when attached to a full-frame digital or 35mm film SLR camera. It has a maximum aperture of F3.5, a minimum focusing distance of 13.5cm (5.5") and a maximum magnification of 1:4.6. The special fisheye design allows maximum creative expression. Sigma's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. The new lens power layout reduces color aberrations. Providing excellent image quality for digital and film SLR cameras. This lens can be used for the scientific applications such as the solid angle measurements of cloud distribution over the sky, the vegetation distribution of the rain forest canopy, etc., due to the quantifiable angle/area relationship it produces. This lens has a gelatin filter holder at the rear, allowing the use of gelatin filters |

I got mine about a month ago and am just back from 10 days in Italy, where I used this extensively.
Sharp, good flare control, lots of fun. The previous reviewer says something about the AF being slow-- which, while true, is only half the story. You're almost always going to be focusing at or near infinity, so it's actually very rare to have to wait. Because this lens has such wide depth of field, I actually usually keep it on manual focus and leave it near infinity.
Actually, the biggest challenge with this lens is composition-- it can be surprisingly hard to find a scene with interesting things in all directions. That said, this lens is *excellent* for inside buildings and crowded city streets. Be aware that outdoors, finding the correct exposure can be difficult for a number of reasons. I did significantly better in M (manual) mode than my camera was doing in A (aperture) mode. (reasons for difficulty include the dark corners in the frame which mess up the camera's metering in some modes, and the probability that the sun will be in the frame and/or there will be both very light and very dark areas in the frame)
This lens is excellent for making spherical panoramas, and for realllllly wide angle shots (I'm de-fishing a lot of my pictures with software).

| This Sigma lens is like a working piece of art. The build quality is high, the images are bright and sharp with excellent color saturation. I use mine to shoot full-screen 360 by 180 panoramas and the results are breathtaking! The best part is that this lens costs 1/3 to 1/4 of what the Canon 8mm lens costs. It's an awesome deal, no matter what way you look at it. The Sigma 8mm is definitely a professional grade lens. |
Outstanding for 360 panorama work

I also bought this lens to use with my XTi (400d) on my 360 panorama rig. Its fantastic for not only that purpose, but lots of creative work as well. It is a great addition to my lens collection and I know a few pros using it for pano work as well.
Enjoy! |
8mm rules on full frame!

Disclaimer: I only have a second hand 8mm/f4, without DG. Use it on 5D.
Pro:
1. Fun factor. There is nothing like it on a full frame such as 5D. This lens rules!
2. Light weight, compact, extremely smooth MF ring! The lens cap is of great design and quality, smooth, secure, and firm, period!
3. Surprisingly low color fringe and flair when light source is in or around the frame.
4. Very short close focus distance.
Neutral:
No HSM, AF can get lost - quite understandable though, for a lens THIS WIDE.
Con:
So so sharpness over all. Very good around F8 - F10. But not too bad wide open either, unlike the Sigma 20/f1.8 and 24/1.8 I have - these two primes are awful wide open at F1.8, but immediately get better stop down (probably a market trick to lure buyers away from Canon's more conservative F2.8 primes).
Bottom line:
This is fun unlike anything else. Full frame at 8mm + 180 degree view angle - sweeeet! I heard the newer f3.5 DG is far better in IQ department. But my fisheye is for fun really, the distortion and the covering all/missing none effect, so pxiel level sharpness is not the most important thing for me here. Besides, I got my F4 copy for $450, what a deal! Just love it! Just be careful with the front element since it can focus so close that it could have touched the nearest object without you noticing... |
Fun

| Very fun lens! Good color, sharp, great distortion. I have a Canon Rebel XTi and with the 1.6x crop i needed something with a lot of distortion. The vignetting can be pretty annoying because you have to edit every photo but it's no big deal. This is a good lens and I normally dislike Sigma. |
