I have read several of the fisheye lens threads and see no one recommending the Canon lens, is there a reason why not to use the Canon 15 mm lens? Will the lens exhibit any cropping with my 30D or 10D?

I think the 30D has the 22mm sensor, like the 20D ..... which means a 1.6 magnification.* You just wont get the full 15 mm out of that lens, because it's designed to disperse the image captured onto the size of a frame of film, ie., 35mm, so on the 30D it will behave like a 23 or 24 mm lens only.* *To get a super wide angle on my 20D, i had to go with the 10-22mm lens, and that's still not wide enough to be fisheye.* mj

The Canon 15mm does not make the full circle 'fisheye' effect the other thread is talking about - The 180 degree coverage for this lens is only across its full-frame diagonal, but on a 30D or 10D the sensor has a smaller area... and the images will be cropped
-> So you can really get more coverage out of a 30D or 10D with the manual focus only Peleng or the full AF Sigma 8mm
