No, that is a common misperception.  Astia (film code RAP)
is the Pro version of Sensia (film code RA).  Provia (RDP II)
and Provia F (RDP III) are not related to either Sensia or
Astia.  RDP II has a different color response curve than Astia,
and better resolution.  Provia F is some dynamite new grain
technology, producing less graininess in a 100 speed film than
the previous low-grain champion, 50-speed Velvia.  If I remember
correctly, the resolutions of RDP II and RDP III are the same.

I'm delighted to see at least one convert!  Although it is
frequently recommended, to my eyes Sensia is just not good
enough for stereo in the 35mm format.  With Provia F now on
the market, the price of RDP II has fallen quite a bit.  For
a small difference in price you can get a much better film
for stereo by switching from Sensia to Provia.

Oleg, you mention liking Astia in 120 and 4x5 formats; it may
not hold up to the more demandnig viewing requirements of 35mm
stereo.
