Originally posted by Groucho ...and since it's a zoom, the amount that covers the sensor depends on your zoom level. At 10mm, you should get a full 180' diagonal fisheye image on your DSLR's sensor. This will probably be somewhat circular on a 35mm lens (kind of opposite of how the Peleng 8mm circular fisheye is almost a normal fisheye on a DSLR sensor, with only the corners blacked out)... and at 17mm, will probably produce a more or less normal 180' fisheye on a 35mm.
I'm still curious if anyone has experience with both and which they prefer. I'm leaning towards buying one anyway, the CA seems to be the only real issue, but that's apparently a problem with other DSLR-friendly fisheyes, too, like the Nikkor 10.5mm.
I don't have experience with the Zenitar, but you can see some Zenitar shots and 10-17's here.

My posting in that thread above has a shot taken using the 10-17 FE in the same place, one at 10mm and another at 17mm. Hope that will give you a feel of the lens.
Here's another couple of the 10-17 I recently snapped.
The first shot was at 10mm, ISO 1600 in P mode. Camera chose 1/3200 sec shutter and f/11!
I didn't have enough time to set it as the kids just happened to be running through and just stopped for a second. Purple fringing was almost non-existent in this strong lighting...the black loop above the "snow" around the sign there was a minor touch, and the kid in the centre had a touch around his left shirt hole. Not visible at all unless you really are looking for it.
Second shot was 10mm handheld, bulb mode, 2.3 seconds, f/16, ISO 400. SR was on.
