Rokinon on ebay goes by the name bestpriceoptics and is offering the 12mm f2.0 for $299. Usually retails for $319 so this is a slight discount. Note that its a manual focus lens. http://www.ebay.com/itm/Rokinon-12m...261?pt=LH_DefaultDomain_0&hash=item43df1ecbd5 It has excellent reviews: http://petapixel.com/2014/06/04/review-rokinon-12mm-f2-0-great-option-astrophotogs-budget/ "Optically, the Rokinon 12mm f/2.0 NCS CS is very good. It’s very sharp at almost all f/numbers, even sharper than the much more expensive Zeiss Touit 12mm f/2.8. I have no reservations recommending it to anyone looking for a nice sharp lens. ... Overall, I really love this lens."
