Any reason why you wouldn't buy a Sigma Merrill and use that in B/W selecting the blue channel only?

Photons of different energy (wavelengths) penetrate the silicon to a different depth.
Using only the blue (top) plane would not capture all the visible wavelength; only predominantly blue. You'd miss the green and red wavelengths that penetrate deeper.
