Have this Canon 5D3 that has issues with the exposure. Two successive picture of the same situation, turn out completely different, 1 overexposed and one normally exposed. .... Could this be a board problem?

The solution was to change the main board in the lens. I used the SPT software to back up the original data, put in an other (used) board, reloaded the data and the occasional overexposure in a series of pictures did not occur anymore. Thanks to Eoghan who had a similar problem and pointed me to this solution and to Chuck to make the main board swap posible.
