This is wrong. The metering cell reads a reflective area off of the shutter
cutain that is of a fixed size in relation to the film mask. Changing the
frame lines via the selector lever simply SHOWS you different frame lines
for different focal lengths. From this you can extrapolate what the metered
area would be if you changed lenses.

The only way to change the angle of measurement of the meter is to change
lenses.

Hope this helps.
