Sigma 50 1.4 - $375 This the newer version - a fantastic lens in great condition. My wedding workhorse for the past two years, I've changed out to a 35 1.4. Includes Hoya SuperHMC filter, box, soft case, paperwork.
Nikon 50 1.4D - $225 In good condition. There is a small mark on the front element - visible in the photos. Does not affect picture quality. My go-to 50 until I purchased the Sigma. Includes UV filter, box, paperwork.
