At The Online Photographer Mike Johnston comments about an article by Charles Cramer that compares medium format digital to scanned 4×5 film. I think one of Johnston’s comments is especially intriguing:

I have a principle I call “the confluence rule.” What I’ve noticed is that the closer two of anything are to each other, the more people tend to work to discriminate between them, and the more passionate their arguments become about which is “best.” This is backwards, in my opinion. To me, the closer two of anything are to each other–the more confluent they are–the less it matters which one you choose.

By the way, The Online Photographer has become one of my favorite photography blogs recently.
