I think that link got buggered.
At last it worked and the visit was very worthwhile. The three photographers are interesting to follow but since they were also filmed, it's not clear how they actually got the video and still of the photographers without some connivance.
Still, of course, one appreciates the trio for revealing some of Porta. However, I seriously doubt that these photographers could have been handicapped with a small Olympus, Panasonic, Pentax, Sony oe seven a mere digicam from Canon or Nikon. Even if the controls aren't intuitive, the camera that's best in the hands of anyone with talent, is the one that happens to be in their hands. A sensitive artist can work with any camera. I do not believe for one moment that all the pictures would be any less impressive taken if this particular Leica was not available.
BTW, the lack of an LCD screen, if valuable, is achieved by simply keeping it switched off and conserving the battery at the same time.
The reasons for getting the Leica MD are more associated with respect for the lineage of the the venerable Leica name and the many masters who relied on their meticulously German engineered film cameras of yesteryear. Even today, Leica glass is almost in the top flight of possible lens choices.
Still, to me, the Leica camera still have the gravitas of the Rolls Royce of small cameras. But that's like staying in the Waldorf Astoria ands paying $2,400 a night and feeling it's worth it. If you can afford it, and your kids can still get a fine education, then it really is wonderful to make do with the finest things in life.
