Which fisheye for my Nikon D3100

[Dean.]

Looking for a fisheye lens for my nikon D3100
After doing some research I've noticed that the 10.5mm Fishy that Nikon produce won't auto-focus on my camera (or many others) so I'm looking for an alternative lens.
Does anybody have any suggestions?
Cheers!

The 10mm Sigma HSM lens seems to be the best one out there?
I believe the HSM means that it will auto-focus on my D3100?

Samyang 8mm is another option, the new one has an exposure chip to allow the D3100 to meter correctly but still no auto-focus.

Focusing shouldn't be a problem that wide anyway, It would probably be more difficult to get it out of focus...

HSM is Hyper Sonic Motor. Yep, the auto focus motor.

I'm struggling to find any 10mm sigmas for sale.

For those who own fish eyes, how do you rate them? Which ones would you recommend and/or avoid?

Get the samyang! Autofocus is near pointless on a fish eye anyhow and Samyang lenses are priced well below thier quality.
