I've never seen one in use. Known anyone who would be caught dead with one. The Sigma 12-24mm f/4.5-5.6 EX DG IF HSM is a full frame lens . So its really an ultrawide. The Nikon 12-24 f4 is a DX format lens. 1.5 crop. But yes you can use the Sigma in cropped format camera. And it works out fine. Sigma is about the only third party lens manufacturer I'd ever buy from. You could compare a Hasselblad Zeiss Distagon 50 against a Leica Summicron 50. But as they are for different formats few would. A more extreme example. But kind of the same thing. Mark William Rabiner markrabiner.com
