This will be great on the new Pentax MILC, where you can brighten the EVF.

4000mm with the K T6-2x TC. -2 stops, I think.

Maybe we should seek input from @normhead (a.k.a. the PF king of TC stacking)... 1.4x plus 1.7x ... I'd *love* to see the diffraction and reduction in sharpness from *that* setup

That really was a steal. Did someone buy it?

It will make a nice soft portrait lens.
