Efke 25, 50, 100

[Henri Toivonen]

I'm a bit curious about these films, they are VERY cheap to order from 
Germany and I have read some comments that they are incredibly sharp 
with minimal grain. So I'm considering to buy a 10pack and try it out.
Though I read somewhere something about limited red sensitivity and that 
you get a "turn of the century" look with them, and I don't really 
understand what this means.

So I ask you, comments on these films?
