I was trying to say that four thirds is by no means half frame WRT resolution. I see the perceived issue as noise levels since the photo-sites on a smaller sensor for the same resolution are by necessity smaller. However there are huge advances in sensor designs, processing algorithms, micro-lens configurations and post processing. There are advantages such as the less angled input to the peripheral photo-sites (given the four thirds philosophy of lens design) and finally compact form factors which make sense to me for four thirds bodies. It seems to depend on your frame of reference. From the film world 1600 ISO or similar, grain would be expected and accepted without comment. Now noise is a problem. The holy grail being 6400ISO equivalent at Kodachrome 25 grain or some such. Oh and a dynamic range of 12 stops of course. I don't know, I have seen some superb results from the E410, 510 and now the E3, not to mention the L1, Digilux 3 etc. Really we must be past film/sensor comparisons. Apples and oranges and all that. To drift back on topic, I wonder what Photokina will bring from Solms or will it be Wetzlar? Some suprises I bet.
