One potential advantage of a larger format (though everyone needs to keep in mind that \"mini MF\" 33mm x 44mm is not that much larger than full frame!) is that it can provide a greater range of usage aperture options
While acknowledging that in many cases the maximum aperture available may be smaller with larger format system lenses, one can use smaller apertures with less effect from diffraction blur in the final print at a given size.
You can use a smaller aperture on the MF system before diffraction becomes apparent but you gain less from stopping down in terms of depth of field, so ultimately you end up back where you started - there\'s no advantage to a larger sensor when it comes to diffraction.
If your medium format lens goes from f/2.8 to f/32 and your 135 lens goes from f/2.0 to f/22 you have the same range of apertures!
