Actually, yes. If you look at the counter, the white trim goes from green at left to neutral white on center. The yellow of the counter goes from greenish at the very edge to a more neutral as you get to the center. I don't think it is a extremely dramatic effect like the one that Maggie posted, but it is very similar to what you get on the M8 with a 35mm or 28mm lens. Seeing as this is a fixed lens camera, I think it should be programmed out.I'm not entirely sure it is all that bad judging from these pictures. There are shadows and reflections from a greenish glass on the shop front. Also paving stones do get unevenly worn when they are next to a wall or window and in one picture they are a block of only four grey slabs against a wall. I spend a lot of time at work having public realm hard landscaping re done because of uneven colouring of the materials used. I'm not saying your wrong, just that I'd like to see more convincing evidence.
can you see any in this one?

As for other examples, look at Sigma's own at the DP1 page. I see it in most of the photos there, but particularly in number 10. The sand at the bottom is very green compared to the sand on center, and this is a very even toned image...the difference is obvious to me. The color numbers of the sand on center are 165,148,133 versus 108,106,87 at the bottom edge...the red is significantly deficient compared to the center.
Anyway, I don't want to derail this thread, it is just something that I noticed and it struck me as very familiar as an M8 user. When it came out people got all excited because they had been hoping for it for a long time and people did not really notice some of the flaws...when they got them in hand they started to see that the pictures coming out of the camera did not look like the world they were looking at and they got angry. Again, I have no interest in bad mouthing the camera, I think it is producing some beautiful results, but there may be situations where you need to be aware of the cyan vignetting unless sigma corrects it in the firmware. Personally, it would annoy me.
