I have this Tokina 10-17mm fish-eye lens for sale, it's only a few months old, and has had vey light use.
The only signs of wear is a tiny scuff on the lens cap.
Selling due to upgrading to FX lens, so this will no longer be of use to me.
Looking for around £300.
UK based, but will ship abroad.
Any questions or interest drop me a PM.
Most of my friends have actually gone back from the nikon 16mm fish-eye to this tokina, even when using d3s, d4 cameras.. You just need to buy a convertor. I just changed .. and have not regretted it ..
