Purchased this locally in 2012 and have used it once. I have a 35 cron and so, have decided to sell this and buy a Sony A7r to play with. The lens is immaculate, no marks, fungus, etc. Has been in it's case in a locked safe for the last two years. Looking for $4,400 net to me. They are selling new for $5,150 at B&H. I have done a number of transactions here for cameras and lenses and not comfortable with paypal. if interested, PM me and we will agree via phone how to complete the transaction. Thanks for looking
