Q-to-K Adapter and HD Teleconverter on Q. Is it possible?

Just curious actually, more likely a dumb question.

Can a Q camera have an HD Teleconverter with a lens (like the DA* 60-250) mounted on the Q-to-K adapter?
Is it possible to have more reach with this setup?

I don't see why not, as long as you have an adapter with an aperture ring.

With the high pixel density of the Q, the diffraction comes very early. I wouldn't use a lens slower than f4. And a lens that is not a premium performer wide open. I don't think there is an interest of using the TC with the 250, the resulting combo will be an f5.6 lens, which must be stopped down a little bit cause of the TC.

yes you can do it...I have examples somewhere with the 1.4 teleconverter but here are some with the 1.7 adapter on the sigma 500mm f4.5..i will keep looking in the meantime

The line between where diffraction reduces IQ and where stopping down a lens increases IQ and DOF is not absolute and varies for most lenses, many lenses perform better stopped down to f5.6 or even f8 when mounted to the Q or Q7 then they do at f4 or wide open. See the adapted lens thread

That has a very long reach! I think your Q setup is floating!
