I have 2 Nikon prime lenses for use with a Mike Tapa adaptor on camera's like the Sony Z7 or S270 (and all other videocamera's with interchangeable lenses). Both with glass in perfect condition.

300 mm, f4,5 - manual aperture - 125,- euros (becomes a 2100 mm on a 1/3 inch camera!)
135 mm f2,8 - manual aperture - 65,- euros (becomes a 1000 mm on a 1/3 inch camera)

I used these on my Z7 with fantastic results.
