Equivalent focal length for MFT lenses

Too many variables

Are we assuming the same pixel count in both sensors or a higher pixel count in the FF sensor?

Are we assuming the same ISO capability or noise level at a given ISO?

Is what you're getting at that the 4/3 lens must resolve twice the lines per inch to achieve the same level of detail as the FF lens? (assuming same pixel count and noise level)

Here's a wrinkle for you:  Some FF lenses can give better edge to edge sharpness on 4/3 than on their native mount because the softer edges are cropped out by the smaller sensor, which only sees the best part of the image.
