  It always goes like this when hunting around for gear, as soon as I purchased the "D"  an "S" turns up at the same price.

 The good side of this sort of lens buying though is if you don't like what you have just bought you can sell it on without losing money.

 

  With all these new FF Nikons bodies these older FF lenses are going up in value!

Well, good if you can; I was never good at that - I either fail to get rid of gear or have to sell it at massive discount to get a deal at all. I would make a terrible salesman.

Though I have to admit, I've had that "cheap'n'nasty" habit myself - for years I was cherishing a Canon 24-85/3.5-4.5 lens, and now, after having given it away to a friend (who upgraded to a 5D Mark III but was missing any full-frame lenses shorter than 80mm *snicker*), I'm thinking of getting another one someday. But this time a silver variant.
