Well done Gary,
For those that seem to want to argue the point, We (I think Warren Kato?)
came up with a simple test.
1. With your 4T(i) set up for a meter reading so both Manual and Auto agree
and are in the 1/15th sec range with Velvia loaded.
2. In Auto mode - Lock the memory.
3. Expose the frame. Which memorizes the exposure setting of "that" OTF
exposure.
4. Now view the display and READ the difference. If my memory serves me
correctly I got +1&1/3 stops.
Bottom line - the OTF meter gives different readings (exposure), with some
films, than OTC metering.
Nuf said!

My spot meter displays 1/10 stops, so,
Grey card: f/5,6.9 versus Kodak Gold 100 f/5,6.2
means that there was a 0.7 stop difference betwen the two.
