Jan_Shim: Yes I do have a burning question and it's none other than the minimum focusing distance ... (cross posted as follows from comments left at Preview page)
I shoot with two 5D Mark IIs professionally and for everything else I use the G11. Essentially two very important considerations: the flip out LCD and the 1 cm macro capability (excellent feature for food photography). The G1X with all the other great features has compromised this with a focusing distance of 20cm (according to Dpreview Specs). The G1X quickly went from "high exciting" to a big let down for me.
Question: Does the bigger sensor result in a magnification at such that at 20cm, it's (by any chance?) equivalent to 1cm on the G11/12?
Very disappointing that manual exposure mode continues to mean manual flash adjustments as well.
