Both are for sale together or separate.

The 18-200 is in great condition. Just some minor scuffing and normal wear and tear- lens is great with no fungus or sratches. Have the box and manual for it as well. $400 OBO

The TC 17e II is a fantastic extender. Great condition, no scratches or scuffing, no fungus and looks almost new- used maybe twice with my 70-200 f4. $350 OBO
