Renaissance of the slow lenses it seems ;-)
I'm fairly tempted to take this one for a ride. It has been a while since my last encounter with a mirror lens (the Tokina 500mm f/8 I believe).

Maybe you mean this one.

Time flies.

Ah yes, something with a T ;-)

Could it be a rebadged kenko 400mmf8?

Since the company is actually called Kenko Tokina... there's a solid chance.

You are right, Toni. The "tokina" is exactly the same lens as the existing Kenko.

They still build these things? I almost choked on my donut when I read the headline...

Ah, time to look in the closet and dig out some old lenses.... ;-).
