I use 2 stops, however this is easily tested with the filter and any meter. Meter scene without filter, then with find the difference.

... If the meter and the film has the same spectral response. The Efke 50 has reduced red sensitivity, so depending on usage you may find it works better with a slightly higher filter factor. Or maybe not. It all depends...

BTW, EFKE 50 in Rodinal 1:100 should be pretty close to 50 to 60.
