I currently have a Mamiya M645 system. The older cameras, not the super and TL are what I love. They are superb cameras. They are made very well, have great acessories, and outstanding lenses. I am always amazed at how sharp they are. I choose this system after asking similar questions around here and getting the answers leading me the M645 and I will ceratainly say that it was not a bad decision at all! This camera is also suprisingly small I think as far as medium format goes when it is compared to a 6X7 Mamiya RB67. The system is very easy to use........
