There are quite a few Leica R adapters on the market and R glass is pretty high-quality so I am not surprised that it covers the GFX sensor pretty well. If you cant find a Leica Wide Angle 28mm f/2.8 PC Super Angulon R the Schneider PC Super-Angulon 28mm f/2.8 should work since the Leica is based on its design. All of the findings above should be accurate for the GFX50S/GFX50R/GFX100/GFX100S. This lens can only shift vertically or horizontally 7-8mm before the vignetting gets too be bad.
