You just need stitching software like Ptgui, Autodesk Stitcher, Autopano.

There are lots of tuts and links to software that can do hdri and stitching here:

thanks beaker, will read those page one after another. so far,the stuff that i found over the net are for circular fish eyes only like the sigma 4.5mm,makes me feel that i bought the wrong lens!

you also need to pan on the nodal point of your camera, or you get paralex and they wont stitch.

Stitching software doesn't really care which one you have because all you do is unwarp the images till the lines are straight. Personally I use the Sigma 8mm fisheye. It and the Nikon one you have is much higher quality then the 4.5mm one.

I use the 8mm Sigma with my 5d Mk2, it works fantastic. I usually take photos in 3 or 4 directions, then use stitcher to set up the pano after i build the HDR files. There was a post a few days ago asking about how to create light probes, i posted my steps in it here.

If you have any questions feel free to ask, i have made about 15 probes so far, i find it fun, kinda makes me sound like a nerd =D

Depending on your camera's sensor, you need either the 4.5mm circular or the 8mm circular. The 4.5 mm is designed for crop frame cameras like the canon 50d, rebel series, and the nikon D 3000, not familiar with nikon. The 8mm sigma is for full chip cameras like the 5d, 1d and nikon D3

You could use a 200mm lens if you wanted though it would require a hell of a lot more photographs to get a full panorama.

I think the worlds highest resolution photograph wouldn't compare to the resolution you'd get from a 360 degree panorama using a 200mm lens.
