RF and close up isn't really a match made in heaven. Most cameras only focus down to 3 feet that includes the Bronica RF cameras, the Fujicas etc... the Mamiya has the close up kit. The old Mamiya Press did have a below and you could focus on the groundglass with the ground glass adapter I believe all Mamiya Press with exception of the Universal were able to do that (least costly MF RF camera as well, with the exception of the Koni Omega)
