with 100LPPMM for film and 100LPPMM for the lens, the best MTF you get is 50 
LPPMM for the system this requires half the sensor count you suggest. The 
Dalsa 11 MPixel sensor meets this criterial very well.

The best you get is 100, the WORST you get is 50.  In reality, you get a
range of 50-100.  The 50 would be called "RELIABLY".
