REDUCED - 14-24MM COMING MONDAY... This is an ultra-wide angle zoom by Sigma -- bought it 10 years ago to use with my Nikon F5. That's a film body for newbies, so it covers FX sensors. It's an f3.5-4.5 lens. It has a bulbous front element -- so no filters. It's very clean and ready to go. If you want an ultra-wide but don't want to spend $2 grand for the 14-24, this is an able substitute and you'll have $1750 in your pocket! REDUCED TO $250, INCLUDING PayPal's 3%, and I'll FedEx/UPS it at my cost. Email if you want photos. Shot pictures with it yesterday.
