Yep sure. As I mentioned it may or may not be significant (to the user and
in the circumstance).
Since this is a theoretical discussion with no-one having the announced
cameras/system here, I was just commenting on a technical aspect of that.
My post was intended to express that the best lenses to use can be the ones
designed for the system, in my view.


If you needed to increase the exposure in the main part of the field by say
two stops for every exposure and apply a colour correction you would
appreciate that the correction comes at a cost of dynamic range, tonal
depth and noise performance for example. It's happening in the corners for
every frame with wides on the M9. Does it matter in practice??? yeah no
maybe depends ;-)

In the case of the M9, I can comment that the amount of correction with
wider lenses is quite significant to achieve the desired result at all. I
was a firmware tester for the system.

The M is another discussion. I just recovered a few poor exposures that
were two stops or more under (albeit minimum ISO) with excellent
results...remarkable.
