fp-mbc100-slides

The FP-MBC100 port base was designed with an external focus knob allowing the use of Nauticam focus gears for the Canon 100mm f/2.8L IS USM, 100mm f/2.8 USM, and the 60mm f/2.8 USM. 

The FP-MBC100 ships standard for use with the Canon 100mm f/2.8L IS USM.  There is also the optional FP-MBC60 available for use with the Canon 60mm f/2.8 Macro USM lens. 

Both flat ports offer 67mm threads to accommodate most close up lenses or flip holders.
