12mm on a full-frame body is fisheye. I suspect you don't really want a fisheye lens but, if you do, Nikon makes the 13mm f/5.6 AI-S. A copy sold a few years ago on eBay for something like $20,000 as I recall. Samyang makes something similar, a 12mm f/2.8 for around $500, but it will be manual focus.Just for discussion, what would you consider for a wide angle of around 12 mm for a FX camera that don't break your bank?
