>From my personal experience I know the OM-1 meter is strongly influenced by
light entering from the viewer (up to 2 stops).
If the lens is slow, the amouth of light from the lens is less, while the
amount of light from the viewer stays the same, making the error more
visible (pictures are more underexposed).
Makes sense?
