Which begs the question, why are most tubes incompatible with the *ist?
Possible the *ist doesn't have the capability to meter correctly with them? I'm not familiar with that model Pentax.

I think Godfrey got it right. The *ist, I believe, lacks the physical aperture simulator. The old ZX-50 was the same. You could use tubes on the *ist, but in manual mode, with metering supplied from some other source. You would need to focus wide open, then stop down to shoot.
The D and DS have workarounds for this problem, but not the *ist.
