I always thought Weston was 0.8 of ISO (ASA) So Weston 80 for ISO 100.
Set the meter to Weston 80 and at 400 it gives f16 at 1/125
So what is this 'new ASA'? And is it the reason why the ASA settings do not quite correspond with the DIN settings on my Ikophot meter?
EDIT: Actually, it's further out than that. If I set it to DIN 21 it reads ASA 40 on the other side.
