| Okay I'm looking into picking up 15mm fisheye and I'm probaly going to go with the sigma over the cano because the canon lens is like 20 years old. Anyways with the crop on my 20D I was woundering what my angel of veiw would be the lens has a 180 degree but with the crop It should work out to a 112.5 Degree but I'm not 100% sure because it is a fisheye so would it be more like a 24mm which has a 84 angel of veiw. Tell me what you guys think |

Ultimately, it just doesn't look that fishy most of the time. This is one of the reasons I bought Nikon cuz they had the fisheye for that angle of view. If you want a real fisheye look you need the sigma or peleng 8mm.
Those both flare up like crazy and can be pretty soft, however.
If just want to add a nice ultra wide-angle prime to your collection with a little bit of distortion then you'd be good. It's gonna be your 112.5* view, wider than a 24mm on 35 mm format. A 15mm fisheye is wider than a 14mm prime, keep that in mind.
If you're wondering which 15mm lens to get, I have a nice canon-brand answer for you, unless you want inferior optics. |

| I looked at couple pics from a 8mm fisheye and I just don't like how ballie it is so I'm going to stray away from that, Your recomeneding the canon 15mm fisheye? My local High end camera store recomened the sigma 15mm fisheye over the canon the Canon is a lens from 84 its as old as me hehehe, and sigma just released a new 15mm fisheye I should probaly rent them both one day and figure it all out, my camera store lets you take the rental of the price so matbe that will be my ticket. |

A 15mm equiangular fisheye on a 1.6-crop body will have the following angles of view:
Horizontal: 88.9°
Vertical: 58.3°
Diagonal: 108.1°
You can make shots look quite "fishy" or nearly rectilinear by where you place straight lines in the image. The Canon, BTW, is a great little lens, and yes, it is quite an old design, but it is still just as viable today as it was then. You don't need fast USM on a fisheye; in many cases you can set it and forget it.
Remember that the Sigma may or may not be compatible with future bodies from Canon, and at some point won't be able to be rechipped anymore. I have no relevant experience as to how the Sigma compares optically.

Canon has a huge investment in the EF lens system, and I don't see them changing it soon. The EF-S lenses are different, but are really just a subset of the overall system, since they share the same electronic interface and an almost-identical mount.
If Canon does change their system, the Sigma will be just as useless as the Canon.

I've the new 15mm DG fisheye (ahem, moderators, the new version is not available on the equipement section) and I like the lens quite a bit. You can see the shots I took with it at the Getty Villa at my site.
On the XT, it's not fishy at all and the distortions kinda look bad. For that money, unless you really want a fish, I'd get a Sigma 10-20. If you really want a fish, Tokina is making a 10-17mm fish for the cropped sensor, from what I heard.
