The RPM-GFX makes a dedicated repro camera out of your Fujifilm GFX.
The Helical Focusing Mount with GFX bayonet accepts a variety of lens mounts. It's a completely modular system enabling you to fine-tune your camera for its designated tasks. The lens mounts enable the use of such outstanding macro lenses as Rodenstock's HR-Digaron 5.6/105 Macro.
Interchangeable extension tubes WHF-7 and WHF-9 set the desired maximum magnification.
