I have a slightly odd trade idea, want to see if anyone is game. I have a nearly new condition 70-200 2.8 VR with all boxes and extras that I would like to trade for a 300mm 2.8 AFI or newer lens, prefer AFS. I do not care about cosmetics but want perfect optics/mechanics. Since my lens is not quite worth the same and I do not have the extra cash I will make up the difference in professional printing services to you or PS training. I print for photographers and museums across the country, teach digital imaging at RIT and write imaging articles for View Camera magazine. I have a custom ink-set that I developed with Lyson out of England that gives me super rich colors and very deep blacks for incredible print quality on a range of Hahnemuhle papers. I would also offer drum scanning or Photoshop training if you have interest in either of those as well. Unfortunately, I have spent a bit much on camera equipment recently and the "allowance" is spent. I can give references.
