An interesting idea, and worth a try as long as you understand that the Canon will not have sensitivity even approaching that of a Mallincam or Stellacam.
So exactly what is the sensitivity of the Canon camera? We know the sensitivity of the Mallincam. However, there are no equivalent measurements for the other cameras. All you have is an ISO value.
I find it interesting that so many people claim that the Mallincam is many many times more sensitive than everything else without knowing how sensitive those other cameras actually are. I don't doubt that the Mallincam is more sensitive. I do doubt that the Mallincam is 6 times or more as sensitive as some of the claims that I have seen state.
Well, one thing you can depend on in general terms: "More and smaller pixels = less sensitivity."
