I think that's right. My Pentax Zoom90wr has the four pin DX and
reads in full stops from asa 25-3200 (... but it's a Pentax ;^)
I have had good experience w/ it and TMZ in "roving chronicler"
mode. Masquerading as a "common P&S", it is really rather
effective - With the TMZ, you can run it No Flash and take
advantage of a fast leaf shutter/tight aperture combo w/ minimal
shake potential. And if you see something afar, it is a simple
matter to switch on the flash. At 3200asa, even a small flash
gains significant throw and achieving the f7.something exposure
at the 90mm end of the zoom is usually possible.
I don't know the minimum aperture, but max shutter is 1/400th.
So there is a certain range to close for flash - but the auto
flash still works excellently beyong this for a good distance.
