This zoom gear is for use with the Tokina 10-17mm attached to a Kenko 1.4 teleconverter for WAM-wide angle macro.
Cost new $175
Sell like new, still under warranty for $125 with $5 shipping to anywhere in USA.
See my other listing for the lens and ZEN DP-100 mini glass dome. Nice compact wide angle system.
