He was comparing a scanned image to the R5.
He said he was using a Epson 600. I bought a V850Pro last December and have been scanning old family photos.
He is also using Silverfast which I have heard numerous bad things about. There are a multitude of settings and ways you scan which impact the outcome.
There is also his developing skills, type of film, processing skills and skill using the digital camera.
I am not sure how much information you can derive from a comparison with so many variables.
