The light metering used by the G2 is described as "centre weighted average light metering" but I cannot find details of the magnitude of centre weighting used. For ex&le, I would be interested to know the weighting given to light received at the centre relative points at the edge of the frame and say, half way between the centre and the edge. It would also be useful to know whether the weighting changes continuously from the centre outwards or whether there is a defined central zone that is given extra weighting.
