Also nice, though, for those wanting to use a Magic Filter is there is a rear filter holder.
However, my 10-17 has nothing to fear about being replaced.

This is bad news. I thought Sigma must have something in the works to fill the Canon FE gap and was pleased to see that they _Finally_ had done it. Not even close and definately no cigar.
The shame of it is that Nikon already has a great WA Fisheye option, only Canon does not. So to whom do they expect this lens to appeal to? I think they missed their biggest potential market.
Now the new 4.5mm seems to me to be much more exciting. I think true circular shots do have their place for artistic shots, and the otherworldly views underwater lend themselves to this. For those looking for something to distinguish some of their shots this is the lens. Now APCS usesrs can join in the fun too. Just don't overdo it.
I might get one of these myself. But this lens is even more specialize than a full frame fisheye and would really be the kind of kit I'd rather borrow for a few special dives than one to own. Maybe we could create a Wetpixel cooperative?

You don't consider the 10-17 Tokina to be a great WA Fisheye for the Canon? Or were you wanting a prime lens FE?

So there still is a bit of a gap for Canon cropped sensor users. Sigma could have filled it--but didn't.
Given the choice I would rather have the full 180 degree coverage and sacrifice a little on image quality and stick with the Tokina. I don't really see any motivation for Canon users to buy the Sigma.
For Nikon its a much harder choice. There are advantages to a prime lens over the zoom and advantages to the zoom over the prime. There is almost room for both lenses in the bag. But Sigma is pretty much a moot point since we already have a good choice in the Nikon 10.5. Only if CA and price are much better could the Sigma be competative. But even then its a small market and always a hard sell for the 3rd party lenses.

On a Canon 1.6x-crop, the Tokina's FOV is ~167deg at 10mm (the same as this new Sigma). To be sure, it's wider than anything else has been for Canon crop-sensor cameras...

FYI, a MF can be fitted to the rear of the Tokina... You just need to be able to trim it to shape and use some tape to secure it...

True, but I'd rather just slip it into a filter holder. Won't stop me, though, from using a MF on the Tokina.

Clearly there must be more going on here than the diffference in crop factor between Nikon and Canon. What is it about the cropped digital design for Canon that makes full 108 degree FOV so difficult?
Sure 167 degrees is still wide, but its too bad that even now there is no 180 degree solution for Canon. So I guess the Sigma will have a market after all.....unfortunately

Maybe we'll all be on to FF before this hole is plugged.

The Nikon 1.5x-crop sensor is ever-so-slightly larger than the Canon 1.6x crop - if lens manufacturers made a 180deg coverage lens specifically for the Canon sensor (smaller image circle), it would have >180deg FOV and/or exhibit severe vignetting on the Nikon. End result: no Nikon buyers.
It's understandable, if unfortunate for Canon users, that they design to Nikon sizing.

Also, as matt pointed out, as evidence of this, the same thing was true with the Tokina 10-17, and I've never heard anyone complaining that they were dissapointed in the angle of view they got from that lens.....
The big diffference that Sigma made was pointing out the fact that there was a difference, as if they had not pointed it out themselves it would not be an issue.
