Still disappointing for a 45mm prime to reach only 2313 LW/PH in this system. A prime of this focal length should score closer to the maximum center resolution level of about 2600 LW/PH. In other systems (e.g. Canon, Nikon, Sony) 50mm primes reach top scores close to the resolution limits of the sensor.

Not sure why you would want to compare a 45mm prime for MFT to 50mm primes on other formats.
The MFT 45mm has a much narrow field of view. Compare it with 60mm lenses on APS-C and 85mm lenses on FF 135 format.
Also, if you just want to persist on 50mm because focal length is focal length, the also consider that the MFT camera would also crop the center of the 50mm lenses, making them perform a bit less than when you don't cop the center and smear the result out over the entire image. You basically have a built in TC.
