FS: SMC Pentax-F 17-28mm f/3.5-4.5 Fisheye Lens

[Micah Kleit]

A rarely used SMC Pentax-F 17-28mm f/3.5-4.5 fisheye lens for sale.   
Once more, I must finance another impulsive purchase by selling this  
lens, which is in great condition I think I may have used it twice.   
I'm including a soft case for it, but I don't have the original box  
or instructions.

$300 plus shipping.  Feel free to respond off list.
Thanks,

Micah
