Medium Format's key advantage is its large film size in old days for more details
while the fastest medium format lens are nowhere faster comparing to today's full frame mirrorless lens options
Full frame 135 format mirrorless just way lighter and compact and more flexible on adapting options overall; and nowaday resolution is more than needed
