film speed equivilent

[memphis]

am looking thru my 1951 leica manual --- there's a few films mentioned that are no longer in production... what would be the modern film equivilents (also, what was the iso / asa / din ratings for the older films)

super-xx
plus-x



also, interesting to note, there's a picture of a couple and child on the subway by look magazine photographer stanley kubrick

Super XX was said to be ISO100

Plus X most likely ISO50

Here is an interesting thread on Super XX at photo.net http://photo.net/bboard/q-and-a-fetch-msg?msg_id=00Azbn

The Plux-X I rememeber, late 1960s, not to show my true age, was 125.

Super-XX was my dad's favorite film and he was always complaining that they discontined it. IIRC it was an even 100 as you say. Super-XX and Verichrome Ortho went bibi about the same time, mid 1950s.

Plus-X is still around, and it's still rated at ISO125.

It was 125ASA after they altered the 2.5 stop safety factor to 1.25 stops, circa 1961.
Then ASA changed to ISO.
Alas I recall this like it seems yesterday, sniff...
I'd a been more upset without Erik's post, Ta.
