Thank you for posting that link again. I have had a look at it and printed out a copy for my Contax bits and bobs file. The implications are very interesting, if the plot is correct and I assume it would be, the plot shows, counting the lines that the meter's sensitivity is highest towards the bottom of the picture or possibly the top, if the plot is not reversed to allow for the actual image on the negative being upside down. The sensitivity also extends far further in a vertical plane than it does on the horizontal, being close to spot horizontally and classic centre-weighted vertically. Have you any idea which way up the image is? I may try by putting my G2 on a tripod in a darkish room and looking at a point source (the ultra-bright LED on my keying mini-torch) to see which is more sensitive, the top or the bottom. I will mentally have to make allowances for exposure when taking shots - well maybe, on a good morning, before lunch and for at least one shot. If the meter is more sensitive at the bottom of the shot this is actually very clever as most pictures (other than snow ones where one tends to compensate in any case or even use a graduated filter) are darker at the bottom than the top, with sky or ceilings usually brighter. Also most shots tend to vary more in brightness in a vertical plane than they do in the horizontal. If I have got it right, someone at Zeiss/Kyocera has really had their thinking cap on for this.
