For Sale Hanimex 500mm F8 Mirror Lens

I am selling a Hanimex 500mm F8 mirror lens (made in Japan). This is a T-mount lens, meaning that it can be adapted to almost any camera lens mount with the appropriate T or T4 adapter. The condition is good, with a smooth focus and nice cosmetics. The overall glass aspect is clean and clear. There is one very fine hairline scratch on the front surface and some evidence of the beginnings of coating loss on the front surface, but none of these will impact use in any measurable way.

I can include one T mount adapter with the sale for the following manual focus SLR film camera mounts (your choice) if desired: M42, Konica AR, Minolta SR (aka MD), Canon FD/FL.

Sold as shown without lens caps.

Price: $35 plus shipping

What is the minimum focusing distance?
(As with the long built, older designs of catadioptric lenses, it was quite long, with later designs it was shorter.)
