Complex designs with lots of exotic/expensive glass to correct distortions and aberrations.
Keep in mind you are also talking about full frame lenses. Most of the cheaper ultrawide zooms are for APS-C. Similar full frame zooms such as the Canon 16-35 and Nikon 14-24 are quite expensive.
yes, but he's asking about primes. The 14L is considerably more than the 16-35, and the Zeiss 15 is 3k. I personally would love to get the Zeiss 15, but then I'd want to be able to use my filters one it, which would require buying a new filter set up as the plates I'm using now are too small for a lens that big. Then you're into buying huge plates as well as a new holder, on top of the 3k lens. Oh man. Money, money, money. I think someone wrote a song about it. . . . .
