100f is discontinued in all formats globally, but is still available at retail
50 and 100 received a package redesign this year and are still available in Japan in 4x5 and 8x10
Only 100 is available in 4x5 in North America (no 50) - check Adorama they have 100
50 is still available everywhere in 35mm and 120
5x7 Velvia is discontinued but available at retail in Japan
Hope that helps?
Perfect answer, thanks Karl!
