Yes it is, however no one sells medium format as a compact solution to anything. Anyone buying into that system knows there's no such thing as truly compact.
But everyone harps on how Mirrorless makes "everything" smaller, when it only makes the Camera smaller. The Sensor size dictates how big the lens must be for a given focal length/fstop
A full frame mirrorless lens cannot be smaller than a full frame DSLR's lens. It's Optics 101.
And for you Trolls out there, please don't go searching for one and come back to me saying but such and such make one that's 1mm smaller
