Hi- looking to trade a mint sigma 24-70 2.8 for a nikon 50 mm 1.2 ais or 85 mm 1.4 ais. Comes with box, soft case, hood, and 82mm filter. Lens is great and works like a champ. Just looking for a nice prime for my F3. Lens retails for about $800.
I know a lot of folks out there aren't hot on the 3rd party lenses, but this is a great example of the lens, and is a great way to get a great focal length zoom for a lens you might just have lying around in a bag.
