I do not think most of us would dispute that.
What IS of interest, to those of us that are old enough to have been around when these "Pro" Cameras were New and In Use, is to use what we could not afford at the time.
I never was a professional photographer and could never...on my income...justify the cost of a Nikon f2 or Canon F1 or Pentax LX, Etc etc.
Now, we can afford to look back at what "The Pros Used".
Kind of a pride of ownership thing.
There are LOTS of 1974 air-cooled Porsches, and circa 1973 BMWs around.
How many 1973 Ford Pintos do you see being saved.
It is simply an appreciation for past quality.
