My experience with seeing results from the Sigma is that the resolution
looked good (not scientific, but at least as good or better than my Sony 717
5.2 MP), but the color was very desaturated - I speculate that this is
because the light has to pass through 3 layers of sensors. This is a totally
subjective opinion.

Subject: dpi vs ppi
Has anyone been able to see a comparison between the Sigma camera using the
Fovian sensor. Sigma advertises an image sensor somewhere from 3 to
4 megapixels But this is the array size because each pixel counts for an
individual R, G nd B because they line up vertically. Now the Bayer CCD is a
checkerboard like array that my Kodak has. In the highest resolution - which
I very rarely use is something like 13.7 megapixels.
So I'm wondering; does the Sigma send 3 bytes of data for each advertised
pixel due to the image sensor design whereas the Kodak sends one byte for
each pixel?
I have used the Kodak in the highest res and like Dave Creek notes it
doesn't necessarily yield a better output. It does loose sharpness for some
reason. The best results are the 6 mp mode - 3000 x 2000. I figure that 3000
pix from the camera (3000 pixels from 36 mm is more than and
inch) stretched out to 10 inches on a print is about 300 printer dpi's -
give or take a few due to cropping - and my prints are crystal clear.
This works for me since the highest res setting on the camera really slows
the camera down too much.
Any experience on the Sigma would be helpful
Thanks
