I am now working with the new Medium Format Digital camera system the Fuji GFX 50r.
This new system blends seamlessly with my medium format FILM systems to the point that the only real difference for me is the loss of my darkroom work when using it!
I am finding that the images from the GFX are pretty much equal with my 6x4.5 film systems and much easier to travel with!
Currently I am using the following lenses:
Fujinon GF32-64mmF4 R LM WR Lens
Fujinon GF120mmF4 R LM OIS WR Macro Lens
GF 250mm f/4 R LM OIS WR Lens
Voigtlander 35mm f/1.2 Black Nokton II ASPH Leica M Lens
Voigtlander Ultra Wide-Heliar 12mm f/5.6 Aspherical M Mount Lens for Leica M
