Just recently upgraded to a 70-200 2.8 ii so I'm looking to sell my 70-300 IS. I bought this lens three years ago for a trip to London and Italy and it has barely been used since. Shows no real signs of wear and functions like it is still brand new. Sells for $650 brand new and anywhere from $400 to $450 used at Adorama. Will sell for $400. See links below for reviews of this lens.
