Philip I posted a response. 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.

Cheers
