Yeah, as far as I can see they are the grey lenses, L series, not the black ones. I was suspicious after I had the 100-400 L series and returned it as faulty to be told that older lenses can be soft and the newer versions, made me wonder if there was the same issue with these lenses.
Well, then they could just be bait and switch shops. There is only one 70-300L lens, there are not variants of the lens. Grey market just means that lenses are being sold outside their warranty regions, and thus you won't be able to have the lenses repaired under warranty (or difficult to do so anyways), and not that the lenses are inferior in some way. Even the price differential between refurbished and brand-new lenses wouldn't swing that wildly.
