Sorry Peter, but from what I've seen Vivitar (even VS1) lenses aren't worth more in Nikon mount. Used Nikkor lenses may, in general, sell for more used than Pentax lenses, but not 3rd party ones. There are also a number of focal length Nikon lenses that are very common, but rare for Pentax (105, 85 & 180/200) that are cheaper for Nikons.
From: [EMAIL PROTECTED] I have often been surprised by the sometimes low prices garnered by some of the older VS1 lenses, despite "cult status".>> Gents. Let me ask you. How much more would it have sold for, all things being equal, in Nikon mount? I think we all have to realise that we are in the minority being Pentax-fanciers.
