Then the Voiglander lenses would become monsters in size and weight, if they would keep f0.95 and the build quality. If they would reduce the size and weight by reducing the maximum aperture, using non-metal materials, and even also leaving distortion corrections etc to softwares, then they are not Voiglander lenses any more.

 

When looking at how little space ring motors take (from lensrentals.com), I doubt they would be much bigger than they already are.

I'm sure many users would like to see fast (< f1.4), reasonably compact and light MFT lenses.
