Don't forget that on a Q with an adapter,
a lot of shorter lenses also qualify as "super telephoto".

I missed a bunch and was updating the post while you posted

Couldn't find this on BH so I decided it wasn't "currently" available.

T-mount isn't directly compatible with K-mount

And with long lenses AF is often desired.
Though I have got my K-50 attached to a 800mm telescope right now...

The Kowa is sold mainly as a lens that can be used as a spotting scope. But it does have all the limitations of a T-mount...just at a price of over $3000...

But how do the get away with calling it a 2600mm tube when it is just a 1300mm tube attached to a cheap 2x TC?

Is the Sigma 150-500 still in production for Pentax mount? All I find for it are used listings.
