Toyo Optics Tou/Five Star MC Auto Macro Zoom 1:4.5 75-200mm 52mm SLR Lens with Pentax K Mount.

I think it will also fit a Canon with an adapter.

If you need specific numbers from the lens, let me know and I will try to locate them for you.

This lens has been untested and sold as is.  Cosmetically, it appears to be in excellent condition.
