Was reminded of this thread when I saw the prices of used Nikon gear shoot up / being stable on ebay.
I had been wanting to try some of the older nikon gear but had put it off as I wanted to use the newly bought old stuff first - was in '11. Now, I see that most of the gear has appreciated in price. Even used Nikon flashes!
Some are attributed to strobist, others to Nex and other micro 4/3rd users buying up the lenses.
Maybe film might pick up too!
