The first time I saw an RB67 it was in the hands of a wedding photographer - he had switched to them as a smaller alternative to the Speed Graphic he had been shooting weddings with .

I shoot my RB67s usually from a tripod, but the rotating back and the appropriate Mamiya grip makes it easy to shoot them handheld with a waist level finder.

The 6x7 negatives are really nice to print from.

And almost all the lenses offer excellent close focus capabilities.
