Any views/feelings or comments on this lens?

If I buy it, I'll be using it on a D300 or D300s. I would love the budget to stretch for the Sigma 8mm but it won't and if I don't need the Nikkor 10.5 then I 'll save my money.

My main question relates to its use versus say a Tamron 11-18 to capture images for 360x180 panos. Is it going to be easier from a stitching perspective to use images from the fisheye rather than the Tamron irrespective of the number of images and which is going to give the best results.

Any advice is appreciated.

Cheers
Tony
