Hi..

I've toyed around with a few old lenses (Schneider Cine-Xenon 1.4/25 and 2/50, Cinegon 1.4/16 and 1.8/10). When hit by direct light, those veil to such a degree that it' almost ridiculous (which is probably ARRI suggested in their catalogues back then to always use the bellow-style mattebox?).
The veiling is so bad that it seems to render the flares invisible.

So I'd like to know:
Is there any trick to make those flare more and veil less?
Can you suggest any other lenses (preferrably S16 safe) that give nice flares but less veiling?

Greetings,
Marc

Since it's mostly the lens coatings that suppress veiling and flare, I don't think there's much you can do besides having the coatings on every element stripped and recoated with a modern formula. That would require total disassembly and would be really expensive. A mattebox with hard mattes would help keep stray light off the edges of the frame and reduce veiling glare until you had a point source in the frame. Those are really old lenses, and lens coating design has come a long way since. Anything more modern would give you less glare.
