Great lens. Purchased from an old friend a few months ago because I thought I was going to be shooting more sports, but this hasn't been the case. Lens is older and has definitely been used, but for its age and amount of use, not abused. I used it to shoot some NE Revolution soccer last September and it performed like a champ.
No photos yet (literally just made the decision to sell). Comes with the Canon leather case, caps and can throw in an old 1.4x extender that was sold with it.
$2000, pretty firm price. Local only (willing to drive to meet with you to check it out, but hint hint, I'm more likely to cut you a deal if you're willing to come to me). Check it out, fall in love with it, and take it off my hands before I change my mind and keep it. Plenty of feedback (see my sig). More than happy to meet in a public place for safety, etc.
Not interested in trades at the moment (well, not photography) but could be persuaded with other high end stuff (guitars, maybe $ towards a decent motorcycle).
(yes, the listing was mistakenly opened reading 300 F/4L IS. My bad, lol)
