Well, they followed one lead from there. The new sensor is CMOS. I 
wonder who makes the sensor?

Makes sense to me. Want a bigger sensor, buy another body and all but 
the few small sensor lenses and all the accessories you already have 
work with the new body. Sound systems approach, I think.

Their cost structure is very different than Nik*n or anybody else in the 
DSLR market. They design and build their own sensors, so producing 
different sizes is easy and relatively cheap. Also, they are really 
selling a lot of the small sensor size bodies. As in all manufacturing 
processes, high volume brings the marginal and average unit cost down, 
sometimes way down. Since pretty much everything else about different 
chips is the same except for the number that will fit on a wafer, most 
of those cost savings go right on over to the bigger sensors. When you 
buy from a foundry, you only share in some of the volume savings, at best.

Did you look at the detailed description? I assume that switching to a 
CMOS and the 4 channel signal processing are to get the noise from small 
sensor sites down to pro level. It's been clear all along that only some 
of the noise comes from the sensors themselves, and other parts come 
from handling, both within and after the chip itself, amplification and 
processing downstream. It looks like they found a way to really reduce 
channel crosstalk and other post sensor site noise.

It looks like a very interesting design, that really can't be compared 
to the E-1 sensor and support electronics. My bet is that noise will be 
well below that on the E-1.

I certainly hope so. I may have a Can*n DSLR for now, but I'd love to 
have an Oly that met my needs.
