I got my tax refund and quicly ran out and bought the Nikkor 10.5 mm f2.8 fisheye, my dream lens. What a sweet lens. Very light and small, it covers 180degrees in a rectangular format. My question is, with this lens do I still need the Sigma 10-20 mm.

Your new fisheye lens promises to be a lot of fun. I look forward to seeing your next batch of photos.

Keep the Sigma 10-20. I have one and I think it's great.

You may wish to compose images at, say 14mm, without the super, yet interesting, distortion of the 10.5mm fisheye. With the Sigma, objects in the near foreground will be larger and more distinct. You often want a distinct object in the near foreground using an ultrawide lens to create an image with attractive composition. The 2 lenses serve their different purposes.

Of course you need the Sigma. How else can you be an avid collector of lenses.
My own take is if you use it keep it if you don't dump/sell/collect it/them.

I have just got my Canon back from service with more hairs in the viewfinder than it went with. (almost) Needless to say it will be returned.

Thanks Dennis and NT. Well my carry-around lens is the Sigma 18-200. I can only get $200 for the 10-20 so I probably will keep it.
