Yesterday I received a used lens from MPB. It is an AF-S VR 70 to 300 G IF ED. Fed X brought the package, and the box was damaged a little bit in one corner and the tape on the bottom of the box had come half way off. This was allowing some of the contents to hang out of the box. The Fed X driver actually pointed this out to me. He also noted that box was damaged, in his delivery notes. When I opened the box with the lens in it and took it out, I saw that the clear window over the distance scale was cracked. The crack ran all the way across the window, length wise. This was a lens that was listed as like new, no damage. My question is this, how big a deal is it. I am worried about the window falling off at some point. I am worried that it might allow moisture to get into lens. What do all you Hoggers think , is it a big deal or not ? Your comments would be greatly appreciated.
