GH1 GH-1 'camera meter' vs 'external meter' question...

I've been setting up a meter test, and for some reason, I've been getting a consistent almost 2 stop difference between my camera 'meter', and two external meters, one reflectance, the other incident.

All this using a 18% grey card, and then checking with Premiere CC's wave form display, and having the 18% grey map to 50% IRE.

When I fudgefactor my meters with an ISO value of 2x, the resulting meter given exposure and the 'camera' meter, as well as the wave form display all 'agree'...

I unfortunately don't have easy access to this sort of test that I did when I first got the GH-1 when it first came out... so I can't tell if I've made some systematic error or not.

I did put the camera in 'standard' mode, and all the adjustments zero'ed as well.

The question is has anyone else used a light meter with the GH-1 and what results did the test yield?
 
I just read that thread in the link above and the only conclusion I can draw is that there is some kind of minor flaw in the GH1 sensor. I have an old selenium cell Sekonic L28c and a bit of a year ago I ran comparison tests with the Sekonic in incident mode and the built in meter on the GH2. The Sekonic hemispheric dome was pointed at the camera lens and in most cases the two came out identical. In the few that didn't they were very close but the exposure reading from the Sekonic resulted in the better exposure.

My advice: If you must continue using the GH1, go by the results you get on the media. But it's really time to "retire" the GH1, if you cannot "budget" for the GH3 then the Lumix G6 is an outstanding choice at the current price of $629 with "kit" lens at B&H, and if you move fast their used dept has one in 9+ condition for $534.95.

The G6 needs no "hack" to produce "nice" video.
