Vivitar 35mm F1.4 for Nikon F mount (useable on full frame or crop cameras. Becomes about 50mm on crop frame) Manual focus with Focus confirm chip. It is the Vivitar branded version of the same Samyang, Rokinon Bower etc. It DOES have the focus confirm chip that shows in the viewfinder with arrows and dot, if you're in focus.
From Wikipedia: Samyang Optics is a South Korean manufacturer of camera lenses for several major brands of third-party mounts for still photography and video cameras. The company was founded in 1972 and has about 150 employees. Samyang exports to 58 countries through 39 overseas agents and distributors.
Samyang products are also sold under a wide variety of different brand names. Some examples are Rokinon, Bower, Opteka, Vivitar, Phoenix and Quantaray.
I bought it for environmental portraits and low light work, but didn't pursue that. Comes with everything that was included in buying it new. All papers, lens hood, lens pouch etc. It might have been used a handful of times. Samyang version sells for $499 currently at Bh photo.
