Why are there no ISO800 B&W film?

Yes, 1200 in DD-X or Microphen -- maybe 1000 in ID-11/D-76. In other words its true speed is about 1/3 stop greater than TMZ. It's also sharper and (in my view) tonally superior, but the trade-off is that as the fastest of the three fast films, it's also the grainiest.

And yes, I prefer it at 1600-2000 in DD-X, though 3200 is good too. It's worth remembering that although 0.10 above fb+f is the ISO standard, anything above about 0.03 above fb+f is printable

Cheers,

In my experience, at least, TMZ is actually sharper and finer-grained than Delta 3200. I do agree, however, that Delta is close to 1/3 stop faster and definitely suffers less from the "pushed look" (blocked highlights) than TMZ.

HP5 @ 800 or 1000 iso
(there was a url link here which no longer exists)

sharper than any negative development @ 400.

I do miss the foma 800T! it was a great film.
