What does the sensitivity of a sensor have to do with the built-in lightmeter of a camera? Are you talking histograms here? One assumes the manufacturer is completely aware of the exact sensitivity of the sensor, and so takes this into account when drawing the histogram. So, compare external meter reading's suggestion of exposure values for a given ISO to the resulting histogram at those same exposure values to see if an adjustment to the meter's ISO setting is required to make it 'accurate' for that sensor. Personally, I wouldn't trust my interpretation of the histogram to not introduce yet another error factor using this method. -- Owamanga! http://www.pbase.com/owamanga
