I am having trouble with an A7SII. I have compared it to two other A7SIIs and the exposure doesnt seem to match. I have reset all of them and set them up exactly the same. Yet and their exposure doesnt match. Two of them do but the other seems to be slightly under on the exposure level. I know its not the most scientific example as a chart would have been more accurate. But they are all the same settings including slog on PP7.
