First off: I'm not anyone's Italian aunt, and never will be.
With regard to the shutter speed thing, remember that to get the
standard 8x10 from 35mm film/sensor you have to enlarge 8x.
Shooting with a 45mm lens on either a m4/3 camera or 35mm camera will
produce approximately the same amount of blur ON FILM/SENSOR.
To get an 8x10 from m4/3 you have to enlarge approx 16x, therefore
the blur produced by the same lens will now be twice as big on the
print.
To bring this blur down to the same size ON THE PRINT you have to use
twice as fast a shutter speed.
