From website info:
o Dynamic Range: 12 bits per channel: Grayscale-- 16 bit digitizing 
on 39 meg
o File Size E3 Mono: 6 MB 8-bit Grayscale, 12 MB 16-bit Grayscale, E 
427: 11 MB 8-bit Grayscale, 22 MB 16-bit Grayscale. E 4 Mono: 16 MB 8 
bit Grayscale, 32 MB 16 bit Grayscale. E6 Mono: 39 MB 8-bit 
Grayscale, 78 MB 16 bit Grayscale.

And still better seems this:
1. ...

2. Without the Bayer filtration's ISO robbing filter factor, they 
utilize over twice the light from the scene, resulting in over twice 
the S/N.

3. The need for developing and the anti-aliasing filter common to 
Bayer pattern dSLR devices is eliminated. Without developing, there 
are no developing errors. Without the anti-alias filter, you can 
actually see how sharp your lenses are with our MonoChrome backs.

Is this as good as it seems?
