There's something to be said for not having interchangeable lenses. For one, even the Rolleiflex 2.8E with its bigger lenses weighs less than a Mamiya C330 with an 80mm f2.8 lens. And while having only one lens choice is limiting, limitations can be a good thing. It makes you go out and take pictures with the camera you have instead of developing bedsores on your ass from searching obsessively for hours on end through Ebay listings for the best price on lens X.
I always smile when I see a Rollei enthusiast with a Wide Angle Rollei, Normal Rollei and Telephoto Rollei scrambling over the rocks when he could have been packing a Mamiya Cxx or Hasselblad with lenses. The bling factor of carrying three cameras is quite impressive.
