I had found it harder to get Astia (my current film of choice for LF landscape) in 8x10 recently. Today I heard from Jeff of Badger Graphics that Fuji is discontinuing Velvia and Astia in 8x10. Only Provia remains available. 5x7 emulsions are still produced in Japan (for now), and Badger stocks Velvia and Provia in that size.
