I only checked once, but it took 4 full stops before.

After adjustment it was within 1/3, maybe 1/2 from full sunlight to average interior room lighting. The built in meter is hard to read real precisely. That was reading an 18% gray card.

I have only 2 questions: Were you sure you were 4 stops off? that's a lot. and 2) what kind of linearity do you have now? That is, is it calibrated at one light level, or is it showing accurate from dark to bright (linear)? Anyway, good show. I thought it was useless.
