PLAMBERT:
Well it’s not like this engineering school project is likely to be widely available in the camera market in say 5 years.
Then the D4 and the M9 are significantly different cameras.
One is incredibly good in lowlight, with a fast AF, and a staggering frame rate, but doesn’t have optically good lenses–unless you use Zeiss manual focus lenses.
And the other, the M9 of course, has staggeringly good lenses, is smaller, but is not good in lowlight, and has very slow buffer.
So the two cameras aren’t exactly in the same category.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
