Through a happy accident I ended up with an extra Tokina 10-17mm Fisheye for Nikon. I have an extra Sea & Sea zoom ring for it as well.
I also have a Nikon 18-55mm zoom (AF-S Nikkor 18-55mm 3.5-5.6 G ED) with a Sea & Sea zoom ring
Tokina 10-17mm $325
Sea & Sea focus ring for Tokina 10-17mm (Also fits Canon EF16-35mm 2.8) $100
Nikon 18-55mm $50
Sea & Sea focus ring for Nikon 18-55mm $100
Everything in excellent condition, both lenses have clean, unscratched front and rear elements and no fungus.
Will sell separately or make an offer for combos.
