If it says DFA then it is a lens designed for digital that covers the full frame image circle. So 150-450 is fully FF compatible

That would sort of be the definition of FF, so yes all the film gear will work. How well it works, well we will have to see.
Originally posted by Oakland Rob I assume F series zooms would also only work cropped...or no?
Umm, no. The F series was designed for film or full frame, so they will be fully compatible.
Originally posted by Oakland Rob I wonder whether say my old Tamron adaptall long zooms (80-210, 60-300), which I think are pretty great anyway, might actually work better than the DA tele zooms?
There are no DA tele-zooms that are FF compatible, though the 60-250 looks like it will be usable with some vignetting. How good your old zooms will be is open to conjecture. On APS-C you have been using only the center of the lens, what they will look like when the whole image circle is used is unknown at this time.
