Exactly.  1 series screens don't have an adverse affect on manual meter 
readings.  To refresh my memory regarding series 2 screen metering, I 
checked my OM-2 that's been calibrated to the 2 screen (with a 50/1.8). 
  With a 35mm lens, meter overexposes  1/4 to 1/3 stop, 24mm overexposes 
about 1/2 stop.  I think telephotos introduce underexposure.
