This is a great lens for landscape/real estate photography.
This is NOT a fish-eye lens and is designed for APS-C sensors.
I purchased this in January of 2014 for $1,008.36 at Lens & Shutter (receipt supplied) and had it out of the box maybe five times before upgrading to a full frame sensor (Canon 5d Mark lll) in March of 2014 and selling my T4i & 70D cameras. It's been sitting in my closet since then, so now it needs a new home.
I would be interested in trades.
